Dear members and friends of OUGS ME,

Welcome to our first newsletter of the year. I hope

you have all had a great start into 2019, and haven’t

given up on your new-years-resolutions yet

For our branch, the year started with a great week-

end in Nancy (France). Françoise Chalot-Prat had

organised a very interesting programme, including a

guided city tour and a very special tour of the CRPG

(Centre de Recherches Pétrographiques et

Géochimiques), where the researchers opened their

labs for us, and talked about their current research.

For spring this year, we had planned a tour to the

Czech part of the Erzgebirge. Alas, this had to be

cancelled (I’ll spare you the reasons for this). Still,

we have some contacts in the area, and some ideas

and plans what we could do once we finally get a

full tour organised. So we still hope to be able to

offer an Erzgebirge tour some time. Next time, it

might be in the German part of the Erzgebirge, and

this might be in 2020 or 2021. We’ll keep you

posted.

The good news is: we have a new tour to offer for

2019! We’d like to invite you to join us on a fossil-

hunting tour in Southern Germany in September.

Details are included in this newsletter.

Later in September, the field trip to the Internal Alps

(Italy, France) is going to take place. This is fully

booked already, and we are looking forward to

reading the reports in our newsletter.

I’d particularly like to invite you to attend this year’s

OUGS symposium. This will take place in Milton

Keynes, at the beginning of August. Milton Keynes is

of course also where the headquarters of The Open

University are based – and this is precisely the

reason, why the OUGS has chosen to have its

symposium there this year: The Open University

celebrates its 50th anniversary this year! So: come

along, celebrate, meet fellow OUGS members, OU

students and alumni … mingle and have fun!

The programme on offer includes presentations of

up-to-date research by staff and students of the

School of Environment, Earth and Ecosystem

Sciences as well as demonstrations, laboratory

visits and course choice discussions.

Full details of the symposium can be found on the

OUGS website:

https://ougs.org/society-events/19/ougs-47th-

annual-symposium-milton-keynes/

And now: happy reading

Marion Seitz

Editor’s note

Hi erveryone,

I hope you will enjoy. Please feel free to give

feedback to newsletter@ougseurope.org.

A happy spring time,

Mainland Europe branch: Annual Report for 2018

The first event in 2018 was our long AGM weekend

in Hamburg, where Elisabeth d’Eyrames stepped

down as branch organiser, and I was elected as

her successor.

This event in Hamburg was a great mixture of

cultural and geological input, with visits to the

famous new opera house, the Elbphilharmonie, on

the one hand, and on the other hand the

Elmshorn salt dome. This is a feature within the

“Liether Kalkgrube” (Lieth chalk pit), where Permian

strata and diapir tectonics are exposed. Thank you,

Fiona Till, for organising that event!

Our next event in 2018 had to be cancelled,

unfortunately. We meant to visit the Erzgebirge in

Eastern Germany, had started organising

everything and found a very good leader fairly soon.

Unfortunately, though, that leader decided at some

point fairly late in the process that he couldn’t lead

us after all. By that time it was too late to find a

substitute for him, so we had to cancel the whole

trip.

In summer, we had a very successful trip again,

when Elisabeth d’Eyrames had a group of about 20

people on her tour to the external alps in France.

Unfortunately I couldn’t attend this trip myself, but

from the trip reports in our newsletter we can see

that it was a major success for everyone.

Thank you, Elisabeth!

Finally, in autumn, a very small group met for

another video-making weekend. We spent some

time in Kassel (central Germany) to produce

material for a short video explaining how to

measure strike and dip in the field. I am currently

working on finalising the video, which will of course

be uploaded onto our youtube channel in due

course.

Another main topic of 2018 was the moving of our

branch website to that of the main OUGS

website, although nearly all of the actual work was

done by Stuart Swales, the OUGS webmaster.

Thank you, Stuart!

The process has not been entirely completed, but

this is only a matter of a couple of more weeks.

During 2018, we have gained and lost members.

Currently, we have a breakdown of members as

follows:

The total number is 26 full members, 6 family

members and several friends of the branch. The

members live dispersed as follows: 12 in Germany,

6 in France, 2 in Switzerland, 2 in the

Netherlands, 1 in Belgium, 1 in Cyprus, 1 in

Luxemburg, 1 in Malta.

Finally, I’d like to thank the OUGS ME committee for

their continuing support:

Terry Warrington, Eva Menge, Françoise Chalot-

Prat, Fiona Till, Gisela Lunkwitz and Dave Kopsch.

I’d also like to thank the many people who

contributed to our newsletter and our group on

Facebook. These contributions make our branch so

dynamic, and I’d like to encourage everyone to keep

sending in pictures and articles, and to post stuff in

our Facebook group.

AAGGMM 22001199

Annual General Meeting 2019

Open University Geological Society Mainland Europe

3rd February 2019 in the Brasserie L’Excelsior, Nancy, France

The meeting was opened at 08:55 and chaired by

Marion Seitz, the branch organiser, who started

by thanking Françoise Chalot-Prat for organizing

a very successful and most enjoyable AGM. Marion

then welcomed the members present; who were:

Elisabeth d’Eyrames, Gisela Lunkwitz, Françoise

Chalot-Prat, Eileen and Neil Lawley, Dave Kopsch,

Eva Menge, Lovella Mojet de Koe, Béatrice Will and

Peter Whiteley (see photo above).

Apologies for their absence were received from

Mike Molloy, Terry Warrington, Fiona Till, Janet

Montgomery, Brigitte Revol MacDonald and Gerd

Weidemann.

No changes were made to the minutes of the last

AGM held at the Hotel Rosengarten, Hamburg, on

4th February 2018 and, as there were no questions,

the minutes were approved unanimously.

Branch Organiser’s Annual Report

The branch organiser’s full annual report, which can

be read in the Society Proceedings 2019, notes that

the Mainland Europe Branch now has 26 full and 6

family members. The AGM was informed that the

video weekend project (started in September near

Kassel, Germany) to produce videos that introduce

the concepts of geology, is almost finished and will

be completed in 2019. The branch organizer

thanked all those who had taken part in the video

venture and all attendees at this AGM. Peter

Whiteley seconded the proposal to accept the

Branch Secretary’s annual report.

Treasurer’s Report

Dave Kopsch substituted for the branch treasurer

Terry Warringon. The treasurer reported that an

over-payment resulted from the car-hire for the

Alps field trip in July 2018 and that each participant

was subsequently reimbursed fifty euros. All

members present today received a copy of the

branch treasurer’s report.

Librarian’s Report

Dave Kopsch, substituting for Terry Warrington, the

branch librarian, had nothing to report. There were

no questions and both the treasurer’s and the

librarian’s reports were approved unanimously.

Webmaster’s Report

Gisela Lunkwitz, the webmaster, had nothing to

report to the meeting.

Newsletter Editor’s Report

Eva Menge, our Newsletter editor, announced that a

total of forty-eight pages had been published in

2018 in the four editions of the Branch Newsletter.

Among the articles in the Autumn 2018 edition was

the second half of a report on our field trip to the

French Alps in June 2018. The editor praised the

sensational quality of the pictures submitted to her

and requested more for this year. Members were

also encouraged to submit web links and the

addresses of topics about geology.

Committee Elections

Marion Seitz informed the meeting that elections

for the post of branch organiser were only required

every two years, and that therefore she would

continue in 2019 and the post be open for election

at the AGM 2020. Terry Warrington was again

confirmed as the branch treasurer and librarian for

2019, and Gisela Lunkwitz agreed to continue as

webmaster. Françoise Chalot-Prat, Fiona Till, and

Dave Kopsch agreed to continue as committee

members without office. The committee elections

were approved unanimously by the meeting.

Programme for 2019 and 2020

Our Branch has scheduled a six-day field trip to the

Erzgebirge Kruzne Hory (German - Czech Republic

boarder) from 30th May until 4th June. This had to

be cancelled just before the AGM. Marion Seitz is

trying to set up another field trip for that time

period and will inform the branch asap if anything

comes up. The Internal Alps field trip from 22nd to

28th September is now fully booked with nineteen

participants. Fiona Till asked whether New Zealand

may be considered as a field trip destination, and

Fiona and Marion Seitz also asked that a three or

four day field trip to the Baltic coast be born in

mind. The committee agreed to investigate a

proposal made by Elisabeth d’Eyrames for a 3 to 4

day field trip to Sicily. The meeting was informed

that the date of the Open University (UK) President’s

Trip (likely to take place in the Eifel, Germany) is as

yet not known but is planned for 2020.

The meeting paused at 09:22 for a short break.

Choice of venue and the date of the 2020 AGM

The meeting discussed and then unanimously

agreed to hold the next AGM in Berlin from 31st

January to 2nd February 2020. Gisela Lunkwitz and

Peter Whiteley, both residents of the city, were

enthusiastic about the choice; they organized the

2012 AGM in Berlin which all participants considered

a success.

New website

The branch organizer suggested that the current

address should be maintained for at least one year,

to see if it has become obsolet due to the

incorporation of the OUGS ME website into the main

OUGS website. This was approved.

The final stages of the incorporation into the main

OUGS website are to take place during the next few

weeks. Marion Seitz and Gisela Lunkwitz are going

to contact Stuart Swales about this.

Any other Business

Our branch organizer informed the meeting that the

OU Geology Society’s (OUGS) main 2019 AGM will be

held in Swindon (a town in Wiltshire, South West

England) on 6th April 2019. Details of the meeting,

which will include a social weekend and excursions,

will be included in our next Newsletter. The OU

South East Branch is planning a Summer Social on

2nd June; details and the location are still to be

arranged, and the OUGS 47th Annual Symposium in

Milton Keynes with be held 2nd to 4th August.

Mainland Europe family members who wish to

receive our Newsletter should send their email

address to Marion.

With no other business to be discussed the 2019

AGM was closed at 09:55.

CCRRPPGG LLAABBSS

OUGSME visit to CRPG Saturday the 2nd

February 2019

At our 2018 AGM in Hamburg Francoise offered for

our 2019 geological trip to organise a visit to her

place of work, the Centre de Recherches

Petrographiquies et de Geochimiques (CRPG) in

Nancy and this offer was gratefully accepted.

The centre is internationally known and renowned

for its work, which is described in the following text,

extracted form the website:

http://www.crpg.cnrs-ancy.fr/spip.php?article1554

“The Centre de Recherches Pétrographiques et

Géochimiques (CRPG) focuses its research on

understanding the earth system, from the initial

formation of the solar system to the planet’s present-

day conditions. Our research teams bring together

geochemists, petrologists and geologists in a combined

approach to the four scientific themes that determine the

life of the laboratory:

Cosmochemistry and Primitive Earth

Magmas and Deep Fluids

Tectonics, Erosion and Relief Evolution

Cycles, Atmospheres, Climates

The activity of the CRPG is strongly influenced by

geochemical instrumentation at the heart of many

research projects. This analytical approach is combined

with a modeling approach and with petrological and

physical simulation. In addition, researchers CRPG are

heavily involved in field trips and sampling conducted on

four continents. The CRPG also implements two national

analytical services of the INSU: the Service d’Analyse des

Roches et des Minéraux SARM and the Service National

des Sondes Ioniques.

The CRPG is a joint laboratory of the CNRS-Institut des

Sciences de l’Univers INSU and the University of Lorraine

UL. The CRPG is one of the laboratories of QTELo, a

research pole of the University of Lorraine. The CRPG is

centered on the Deep Earth and the Continental Surfaces

and Interfaces divisions of INSU. The center houses about

eighty people.”

The work of CRPG is not top-secret but security for

access to the centre is high and those wishing to

visit had to register 20 days beforehand. Most of

the machines used at the centre are very

specialised, sensitive and expensive and some of

the samples analysed, rocks from the Moon, Mars

etc. are also very valuable. So we were booked to

arrive at 09:00 and expected to leave soon after

12:00. With five different presentations on the CRPG

work and a short coffee break in between.

As we are used to walking around in snow on our

AGM weekend trips we asked if the building could be

suitably chilled but the only offer was -200°C in the

laboratory where they freeze the noble gases and

this seemed a bit OTT so we had the luxury of

attending our main AGM trip for 2019 wearing

indoor clothes!

An initial introduction was given to all twelve of us,

in a corridor that had on walls either side some 8

display cabinets containing wonderful examples of

the different kinds of rocks, crystals and minerals;

then we split into two teams of six and started the

tour of the various laboratories in the centre,

accompanied by one of the specialists, whose

names and specialities will be mentioned later and

together at the end.

Picturesque displays of minearls in the

corridor.

Here it is also worth noting that everyone who

talked to us knew their stuff very well, was proud of

what they were doing and proud of the CRPG centre

- and rightly so. The word 'very' is hardly strong

enough to describe some of the features of our

tour: very old, small, hot, cold, where some of the

rocks analysed are not just millions of years old but

billions of years old, small as in a few microns (one

micron being one millionth of a metre), hot where

some laboratories have heating devices capable of

1'800°C and cold where the noble gases can be

frozen down to -200°C. We were shown one

machine developed inhouse that was capable of

heating to 2'800°C!

Béatrice Luais explained some of the processing for

mass spectrometry isotopic measurements. On a

sheet she gave us the following text of information:

“High precision analyses of radiogenic and "non-

conventianal" stable isotope variations contribute to

nearly all of the research themes pursued at CRPG,

including cosmochemistry, early Earth evolution,

magmas, and climate and erosion. They also critically

constrain specific applied studies, for example on the

origin of metal deposits, or the assimilation of metals by

plants.

Elements of interest are first extracted and purified

under clean lab conditions, then analyzed by TIMS

(Thermal Ionization Mass Spectrometry) or MC-ICPMS

(Multi-Collector Inductively Coupled Plasma Mass

Spectrometry).”

Evelyn Füri gave us a tour of the laboratory where

CPRG investigates the rare gases and the most

interesting information that I remember from her

presentation was that the noble gases are frozen

down to around -200°C and then re-heated and as

each vapourises at a different temperature the

scientist conduction the investigation can extract

the particular gas at the crucial point.

Again a lot of very complex machinery in the lab!

Etienne Deloule introduced us to the lab where

CRPG investigates, among other things, trace

elements and isotopic ratio measurements and

dating by ion microprobe.

A speleothem display that allows to

deduce paleo climatic conditions

Francois Faure gave us a short lecture on some of

the things CRPG do in the way of experimental

petrology, where they try to emulate the formation

of magmatic rocks and crystals and this laboratory

is where we saw the home-made oven capable of

cooking at 2'800°C!

And last but by no means least Chistophe Cloquet

gave us a talk on some of the work taken on by

SARM (Service d'Analyse des Roches et des

Minéraux), which analyses rock samples sent

usually by other government offices but also from

private companies. As with all of the other labs the

SARM laboratories have a great range of technical

equipment and very thorough procedures to ensure

cleanliness. The lab is capable of handling more

than 6'000 samples per year.

The CRPG website has a mine of information about

the centre itself and the studies it performs and

many links to other websites and to scientific

reports from world-wide - most of the latter in

English.

So in conclusion our many thanks for sparing their

time and giving us such an informative and

interesting visit go to Béatrice Luais, Evelyn Füri,

Etienne Deloule, Francois Faure and Christophe

Cloquet and very special thanks to Francoise for her

original proposal and for arranging our visit so well.

A story about clinometers, videos and

the Korbach Dachshund

Last autumn, a small group of intrepid OUGS ME

members met in Kassel (central Germany) for

another episode of our long-term project „making

videos about basic geological techniques and

skills“. This time we wanted to show how to

measure strike and dip of an outcrop – i.e. how to

use a clinometer to investigate the orientation of

an outcrop in space.

Filming a video means of course: getting decent

footage. Therefore, we chose two geological points

of interest in the area, where we could expect to

find some good layering and strata that would

provide good opportunities to measure strike and

dip of an outcroup.

Photo 1 trying to get a good shot for the video

The Korbach fissure

The Korbach fissure is the second oldest fossil-

containing fissure in the world. Within Hesse, it is

the second most important palaeontological site,

after the Messel pit.

Photo 2 The Korbach fissure

250 million years ago Korbach lay close to the

equator and was flooded repeatedly by the

Zechstein Sea. After the deposition of the Randkalk

limestones the Zechstein sea temporarily retreated

from the Korbach region along the eastern margin

of the Rheinisch Massif.

During the regression of the Zechstein sea, a

tectonic event led to the opening of the fissure. The

infilling of the fissure by bone-bearing sediments

apparently occured fairly rapidly. The relatively

fine-grained sedimentary material was probably

introduced into the fissure as an aqueous, highly

concentrated suspension, possibly as the result of

flash floods produced by (perhaps seasonal)

rainstorms.

The fissure fill opened in a tectonic lineament

formed in oncoidal limestones of the Randkalk of

the lower Zechstein. The fissure has been filled with

dolomitic mudstone, which is reddish-purple in

some areas but pale yellow in other places. The

reddish deposits are fairly fine-grained whereas the

yellowish deposits tend to be somewhat more

coarse-grained and diagenetically indurated.

Photo 3 sketch of the korbach fissure

annotated

The yellowish mustone deposits are pockmarked by

numerous solutional cavities, which are lined with

calcite crystals. The mudstone fissure filling shows

no obvious stratification. At a depth of about 5 m

below the present-day top, there is a layer of

numerous angular blocks of limestone, which reach

a diameter of up to 60 cm. These blocks, many of

which are encrusted by iron and manganese oxides

and are deeply reddened by subaerial weathering,

represent the overlying Rosetten-Kalk. The

Rosetten-Kalk was eroded away in the immediate

vicinity of the quarry during the subsequent

geological history of that area1.

Photo 4 view from the nearby museum to

the Korbach fissure

The Korbach Dachshund

Within the fissure filling, a diverse central European

assemblage of Late Permian terrestrial tetrapods

was found. Similar assemblages were previously

known only from the Upper Permian of Russia,

Scotland, and South and East Africa. The occurrence

of the basal cynodont Procynosuchus is

paleobiogeographically significant because this

taxon was previously known only from the

Dicynodon lacerticeps-Whaitsia assemblage zone of

South Africa and the Madumabisa Mudstone of

Zambia. The geological context of the Korbach site

permits a rather precise chronostratigraphic

placement of the tetrapod assemblage in the

interval between Zechstein 1 and 3. The Korbach

tetrapod assemblage is late Tatarian in age. 2

The Martenberg outlier

This outlier is about 8 metres high, and also known

as the „Red Cliff“. It is a prime example for

sedimentation of a submarine volcano, during the

Middle and Upper Devonian (from about 400 to 360

Ma). This time period has been named the „Adorf

step“ after the close-by village Adorf. To this day,

researchers investigate the fossils at this outcrop,

and have done so for more than a hundred years.

The Martenberg outlier has become a type locality

for the particular sequence of strata laid down

during this time, i.e. for the Adorf step.3

Photo 6 the martenberg outcrop

The name “Red Cliff” refers to the obvious colouring

of the rock, which in turn shows the presence of

oxidised iron. During the Devonian, when submarine

volcanoes erupted, they produced iron-bearing

thermal water, and subsequently iron-rich mud.

This solidified into red clay iron ore. With an iron

content of 62%, the red clay iron ore became the

basis of the local mining industry.

The red clay iron ore was subsequently covered by

limestone, containing many fossils such as

cephalopods, brachiopods and crinoids. Because of

its importance, this locality is also a globally

accepted reference for cephalopod stratigraphy4

Photo 7 sketch of layers of martenberg

outcrop.

This Sketch sjows from bottom to top: iron-rich

limestone (Givet step), limestone (Adorf and

Nehden step), clay shale.

In the end…

We had a great weekend, thinking about strikes and

dips, getting to grips with the geological concepts

behind them, producing video and audio footage –

and discovering the geology of the Northern Hesse

area. The resulting video file can be found on the

OUGS ME youtube channel by Easter

Jura Fossil Hunting Tour 2019

In early September, we are going to explore a few

quarries in southern Germany, where you are

bound to find fossils that you can take home.

Stefan Mohr has prepared a tour for us that includes

sites where he has previously been himself with his

family some years ago and therefore knows well. In

addition, we are going to visit a couple of museums

in the area.

Photo 8 Fish, 1m, well prepared, Museum

Solnhofen

The locations are going to be: Eichstätt, Mörnsheim,

Titting, Solnhofen, Mühlheim and Holzmaden –

some of them well known for their Jurassic history

and of course their fossils.

Photo 9: Fish from Solnhofen and

Mörnsheim, professionally prepared

En route to the quarries, we’re going to pass other

points of geological interest, like the so-called “12

apostles” near Solnhofen. Find more on them at: www.lfu.bayern.de/geologie/geotope_schoensten/62/doc/62_schautafel.pdf

Photo 10 Jura Fossil Hunting 2019,

findings from previous tours

All localities are easily accessible with car parking

nearby, so that everyone can take part. You can

even bring the kids !

Overall, this tour is about hunting and finding

fossils. Of course we’re also going to learn about

the local geology, but this time the emphasis is less

on academical knowledge, and more on hands-on

practice, and above all: fun and let us get our

hands dirty!

Quick facts:

Accommodation is going to be in youth hostels or

similar.

At the start of the tour, the group could meet in

Nüremberg and leaving could be potentially from

Stuttgart (or maybe vice versa, will be decided when

planning ist completed).

Transport: private cars

The cost is IRO of 250 Euros per person.

Date: 4th to 9th September 2019

For further infos, and to register your interest:

please contact Stefan Mohr at stefan@familie-

mohr.com or Marion Seitz at marion@seitz.org.

Please also indicate whether you are willing to drive

with your car and whether you could take

passengers.
