Lab 5- Fossil Preservation ( Taphonomy)
As we begin to leave the world of sedimentary rocks behind (although not forgotten!), we'll turn
toward paleontology as the focus for the rest of this semeste r. Fossils are not only awesome (although I
may be biase
Historical Geology 4: Biostratigraphy
Once the depositional environment is known from a sedimentary rock, geologists
can start making big picture interpretations of geography, climate, and animal ecology
for that rock. Last week you created your own inter
Historical Geology 3: Depositional Environments
Not all sediments are deposited the same: beach sands are deposited under
conditions that are vastly different than the mud found in a quiet backwater swamp.
Understanding these depositional environments is
Historical Geology Lab 1: Identifying Sedimentary Rocks
The focus of the first few labs in this course will be sedimentary rocks. These rocks cover about
of the Earth's land surface, and are formed by a multi-step process.
