Clastic Sedimentology: notes and PowerPoint presentations are available from:
The study of sediment and sedimentary rocks that are made up of particles that are the solid products of weathering at or near the Earth’s surface.
Gravel Sand Mud (silt and clay)
Conglomerate Sandstone Siltstone and Shale
Purpose of the course:
To introduce terminology and fundamental concepts for the description and interpretation of clastic sediment and sedimentary rocks.
Why study clastic sediment? notes and PowerPoint presentations are available from:
Sedimentary rocks make up only 7.9% of the Earth’s crust.
66% of the surface of the Earth is covered by sediment or sedimentary rocks.
Humans interact with the Earth largely at or near its surface.
Grow food on it. sedimentary rocks.
Build structures on it.
Take resources from it.
At the same time they….. sedimentary rocks.
Hide garbage and other waste material in it.
Modify its physical and chemical properties so that it is no longer useable by them.
It is important to understand the various properties of the sedimentary cover and have systematic methods for describing these properties.
Sedimentary rocks record the history of changing environments on Earth.
Based on the recognition of the signature of changing environments over time, as preserved in the rock record.
Environmental interpretation of rocks
Age of rocks
= Earth History
Large scale cross-bedding in 240 environments on Earth.
million year old rocks in the
= windblown sand dunes; the
Central US was a desert at that
Environmental interpretation: environments on Earth.
The present is the key to the past.
By examining the characteristics of various environments on Earth today we can interpret the environments in which ancient sediments were deposited.
Age of rocks: environments on Earth.
Based on relative age (relative to associated rocks)
absolute age (radiometric dating).
The history of changing environments on Earth.
ERSC/GEOG 2P16 focuses on: environments on Earth.
The description and classification of clastic sediment.
Processes and their products in the sedimentary record that aid in interpreting ancient sedimentary environments.
