Environments
A. Weathering (phys. & chem.)
B. Erosion (wind, water, glaciers)
C. Deposition (deserts & bodies of water)
D. Compaction & Cementation (glue)A. Because of mineral rich ground water
A. Clastic – Made of fragments from other rocks and minerals. (sandstone, siltstone, conglomerate)
B. Chemical Evaporites – Minerals build up in bodies of water that have no outlets and as water evaporates minerals are left behind. (halite, gypsum)
C. Organic – Clastic or chemical sedimentary rocks that contain the remains of animals or plants. (coquina, limestone, coal)
Sandstone
FINE-GRAINEDConglomerate
COARSE-GRAINED
Siltstone
VERY FINE- GRAINED
Shale
ULTRA FINE-GRAINED
Coal
Fossiliferous Limestone Coquina
Source (MTs) >>>>>>>>>>>>>Far (Ocean)
Course Medium Fine
Course – Small to large stones. Glaciers, not far
from source.
Medium – Sand sized particles.
Fine – Clay sized particles. Remove far from source.
All cave formations!
A. Clastic – Glaciers, desserts, beaches, lakes, deltas
B. Chemical evaporites – Caves, salt lakes & seas, ocean
C. Organic – Swamps, deltas, reefs, lagoons, ocean
Deltas
