News & Announcements

Fieldtrip to Magpie Creek Sturt Gorge Recreation Park

The GSA SA Division would like to invite GSA members and guests to participate in an excursion

to Sturt Gorge/Magpie Creek. This will be led by Colin Conor. Adelaide is fortunate enough to

have a spectacular Sturt Gorge that provides a snapshot into when Earth experienced a major

glaciation. This site is one of the first places in the world to show evidence of glaciation during the

Neoproterozoic. Please come along and walk back in time with expert Colin Conor and learn about

the geology in our backyard.

This event will be weather dependant, we plan to run it from 2 to 4 pm. This trip will have a

maximum of 20 people, however, if we have more than 20 people Colin has kindly offered to run it

twice. Upon registration you will receive an email with more details.

Abstract: There are over 800 million people in the world that live close to active volcanoes and so understanding how volcanoes work and what triggers volcanic eruptions is crucial in order to reduce risk to humans from volcanic hazards. In the lecture we'll take a journey deep into the volcano to explore why and where we get volcanoes on Earth and what makes some explosive and others not. We'll look at how science can help us to understand how fast molten rock moves to the surface beneath volcanoes. We'll also delve deep into Australia's rich and fascinating volcanic history to determine how likely a future eruption is in Australia, what the warning signals might look like and how much time we may have to prepare should we detect signs of activity.

Bio: Heather Handley’s research unravels the secrets

held in the chemistry of volcanic rocks and their

minerals to answer questions such as what triggers

volcanic eruptions? and how fast does magma travel

from its source to the Earth’s surface? Heather holds

a PhD in Volcano Geochemistry from Durham

University, UK and 1st Class Bachelor of Science

(Honours) in Geology from The University of

Edinburgh, UK. In 2012, Heather was awarded an

Australian Research Council Future Fellowship to

advance our understanding of the timescales of

Earth-system process. She is Co-Founder and

President of the Women in Earth and Environmental

Sciences Australasia Network (WOMEESA) and was

recently appointed as a Co Editor-in-Chief for Earth

and Planetary Science Letters. Heather received a

NSW Young Tall Poppy Award in 2014 in recognition

of her research excellence and passion for science

communication and has led more than 40 outreach

events and workshops. She frequently writes for The

Conversation, has given over 60 television, radio

and print interviews and has featured in

documentaries for National Geographic and

Discovery Science. She is also mum to two very

curious young girls.

GSA GOLD

The GSA GOLD speaker for Tuesday, 1st June 2021 is Professor John Foden, Associate

Head of the School of Earth and Environmental Science, University of Adelaide. He will

present a talk entitled: Lessons from Fe isotopes in the understanding of magmas and

hydrothermal ores.

Please register here. Following registration, you will be sent a link to attend GSA GOLD on

Zoom. Registration for GSA GOLD is free for all GSA members. Non-members can also register

for just $10.00.

Watch past GSA GOLD lectures on GSA’s YouTube channel here!

John Foden is an Emeritus Professor in the Department of Earth

Sciences at the University of Adelaide. After an undergraduate degree

at ANU, where he was inspired by the teaching and research of Alan

White and Bruce Chappell, John briefly entered the minerals industry

with a spell working with ESSO Minerals prospecting for copper in

Queensland’s Bowen Basin. John then went to Tasmania and

completed an honours degree under the supervision of Mike Solomon

and Rick Varne. After another year or so as a research assistant both

in Tasmania and for a while at Macquarie University, he headed back

to Tasmania and did a PhD under the supervision of Rick Varne on the

geochemistry and petrology of modern arc volcanics from the eastern

Sunda Arc, Indonesia. Since completing his PhD, John has been at the

University of Adelaide, first as a post-doc and then as a member of the

academic faculty where he was promoted to Professor in 2006. John

has twice been Head of the Department Geology and Geophysics

(1995-1998 and 2003) and is currently Associate Head of the School

of Earth and Environmental Science and head the School’s Post-

graduate school (Research Education Committee). Throughout his

career, John has maintained an active research interest in the issues

of the geochemistry and the source of arc magmatism and on the

application of geochemical and isotopic methods to the understanding

of magma genesis both in ancient and modern subduction settings as

well as to intra-crustal magma genesis (granites).

GSA Specialist Group in Economic Geology ‘Facets of Exploration’ Webinar

The GSA Specialist Group in Economic Geology invites you to attend the Facets of Exploration

Webinar on Wednesday, 16 June 2021.

Speaker is Franco Pirajno from the Centre for Exploration Targeting, The University of Western

Australia, who will be presenting the talk 'Alkaline complexes and carbonatites'.

Time: 1.30 pm - 2.30 pm (ACST: SA, NT)

Following registration, you will be sent a link to attend Facets of Exploration on Zoom. GSA

Members attend for free and non-members can register for just $10.00.

Please register here via Eventbrite

Abstract:

Intracontinental alkaline complexes and carbonatites commonly occur

in rift-related settings, best exemplified by the Cenozoic-present day

East African Rift System. Examples in the ancient geological record

are more difficult to unravel due to subsequent overprinting during

tectono-thermal events unrelated to the original rifting. In the present

paper, with the exception of the Bayan Obo carbonatite, I have used

examples of anorogenic alkaline complexes and carbonatites that are

effectively pristine and unaffected by later geological events. In this

context, I report on two alkaline complexes and associated

mineralisation in Namibia (Brandberg and Erongo) related to the

opening of the South Atlantic and the Paraná-Etendeka large igneous

province.

With regards to carbonatites and associated mineralisation, I discuss the exceptionally well-preserved

Kruidfontein and Goudini in South Africa, Mount Weld and Gifford Creek ferrocarbonatite complex in

Western Australia, the controversial Bayan Obo in northern China and the carbonatites of the Mianning-

Dechang belt in SW China. It is proposed that all these igneous systems are formed by processes of

partial melting in metasomatised lithospheric mantle, induced by upwelling mantle plumes. Furthermore,

it is contended that these alkaline and carbonatite igneous systems are formed in the distal sectors of a

mantle plume due to lateral transfer of volatiles, resulting in low degrees of partial melting in the

metasomatised sub-continental mantle lithosphere.

WOMEESA Virtual Seminar Series

On the first Wednesday of each month a woman in Earth or Environmental science In Australasia

will present a seminar about their research and their career pathway. The seminar series aims to

increase the visibility of women scientists and provide inspiring role models for other scientists and

science educators. Seminars will be hosted live via zoom.

Next seminar: Wednesday 2nd June 2021, 1:30 pm ACST (Adelaide time)

Dr. Rachelle Kernen (The University of Adelaide): Creating and Promoting Gender Equity

and Diversity in Professional Geological Societies.

Register here for zoom details.

Upcoming seminars:

Wednesday 7 July 2021: Dr. Teagan Blaikie (CSIRO): “Aeromagnetic interpretation of the Tanami Region

and northwest Aileron Province”.

Wednesday 4 August 2021: Dr. Jacqueline Halpin (University of Tasmania)

Past and additional seminars can be accessed on the WOMEESA YouTube channel.

Diversity drives innovation. When professional organizations allow

gender inequity to persist, they continually lose talented, valuable

individuals who drive economic growth and profits. According to

membership data collected by the American Association of Petroleum

Geologists (AAPG), American Geophysical Union (AGU), and the

Geological Society of America (GSA) there is evidence of continued

gender inequity in professional geological societies, particularly, in the

AAPG. Specifically, there are remaining inequities in the percentage of

women holding leadership and technical positions, publishing articles,

giving distinguished lectures, and receiving technical and service

awards within AAPG, even when compared to the proportional

percentage of AAPG members. Because the AAPG is a major

international geoscience professional organization, this inequity

greatly contributes to the gender and diversity disparity that we see

today in the greater geoscience community. The recent compilation

and comparison of historical AAPG award and leadership role data

allow for an opportunity to provide solutions to advance gender equity

and give meaningful power to diversity in AAPG’s most visible and

prestigious opportunities. By addressing this issue and implementing

meaningful measures to improve gender equity, professional societies

such as AAPG, can demonstrate tangible efforts to eliminate the

discrimination, bias, and barriers many women encounter and support

women in having equitable opportunities as professional geoscientists.

Magpie Creek Geological Trail – Sturt Gorge Recreation Park

The Field Guide Subcommittee of the GSA SA Division have produced a new geology field guide

for the Magpie Creek Geological Trail, in Sturt Gorge Recreation Park. It was compiled by Colin

Conor (STEM, University of South Australia) and Cynthia Pyle (Field Geology Club of South

Australia). Adelaide is fortunate in having spectacular gorges that dissect the steep scarp-face of

the Mount Lofty Ranges. The Sturt River not only displays a fascinating landscape, but also

erosion has created a window that allows an excursion into the depth of time. The 244-hectare

Sturt Gorge Recreation Park protects the heritage-listed Sturt Gorge Glaciation Geological Site.

The site is one of the first places in the world where rocks were found to show evidence of

glaciation (Sturtian Glaciation) occurring about 665 million years ago, prior to the existence of

animal life.

The newly published field guide explains why the landform exists and what the rocks tell us about

the history of the Earth, including ancient changes in climate. Clues are given in the rocks that

crop out along the steep banks of the Sturt River and its tributary, Magpie Creek. What we see

now is a snapshot of the immensity of geological time represented by scraps of geological history

written in those rocks. The rocks contain evidence for a lengthy period when the Earth was prone

to cyclical freezing. At times glaciation was so extreme that the whole world is thought to have

been enveloped extensively or entirely by ice. This period is known as the ‘Cryogenian’, popularly

referred to as ‘Snowball Earth’. Two components of the Cryogenian are represented in South

Australia – the Sturtian and Elatina (or Marinoan) glaciations. Exposed along Sturt River in the

recreation park are sedimentary rocks that were deposited during the Sturtian Glaciation (Sturt

Tillite) and that were deformed and folded in the Cambrian at c. 500 Ma during the ancient

Delamerian Orogeny.

Geoscience Pathways Project Update

ATTENTION EDUCATORS

You may or may not be aware that the Australian Curriculum, Assessment and Reporting Authority

(ACARA) has recently released some proposed revisions to the Australian Curriculum on April 29.

These revisions, if carried forward without change, will significantly impact the teaching of Earth

and Space Sciences (Foundation to Year 10) from next year.

For this reason we would encourage all those interested in geoscience education to engage with

the public consultation process, open until Thursday 8 July.

ACARA’s consultation website hosts a number of resources, but we expect that you will find the

comparative information sheets for Science F-6 and Science 7-10 to be particularly useful, as they

outline both the current and proposed curriculum for each year group.

Large Igneous Province: New insights into Mesoproterozoic magmatism

Monday 7th June 2021

South Australia Drill Core Reference Library or Online

The Geological Survey of South Australia is hosting a one-day workshop to review the latest

geoscience on Mesoproterozoic magmatism in southern Australia.

The focus will be on new geoscience of the Gawler Range Volcanics and Hiltaba Suite of the

Gawler Craton.

Heat and material inputs into the crust during the early Mesoproterozoic formed these units which

represent one of Australia’s great large igneous provinces extending across a region of at least

180,000 km2.

This event was also responsible for widespread alteration and fluid flow, including formation of the

Olympic Dam Cu-Au-U-Ag-REE deposit and related deposits of the Gawler Craton. Presentations

will include:

• Mesoproterozoic mafic rocks of the Gawler Craton

• Geochemical constraints on the petrogenesis of the Gawler Range Volcanics and Hiltaba

Suite

• Stratigraphy of the Gawler Craton’s Mesoproterozoic magmatic rocks

• Duration of magmatism from high precision geochronology

The workshop will be held at the South Australia Drill Core Reference Library and will be available

as a live stream.

A light lunch will be provided at the end of the workshop.

Following lunch attendees to the in-person event will have the opportunity to inspect relevant core

and rock samples.
