Why sedimentology is important Fact 1: You live right next door to some of the most impressive and important modern sedimentary environments on the planet. Fact 2: You live on top of Quaternary and Tertiary sedimentary "basement" rocks. Why sedimentology is important Fact 1: You live right next door to some of the most impressive and important modern sedimentary environments on the planet. Fact 2: You live on top of Quaternary and Tertiary sedimentary "basement" rocks. Fact 3: Most jobs in geology are "soft rock"related. Sedimentary petrology is used in...

GY 402 Assessment Do not be offended when your stuff come back looking like this: constructive criticism is a good thing GY 402 Assessment Incidentally: Failure, not success, is the norm in research too much hand holding is not necessarily a good thing rethinking research questions is desirable Past GY 402 Grade distribution Past grade distribution (19 years of data). A: 49% B: 44% C: 03% D/F: 01% WD: 03% Survival in GY 402 1) Keep track of assignment due dates (Calendar) 2) Check your JAG E-mail daily 3) Become familiar with the class website: www.southalabama.edu/geology/haywick/gy402 4) Work well with others (share duties) 5) Do not stay quiet in class Thin section petrography: Modern sediment (John Brewer Reef, Australia) Foraminifera Bryozoan 0.75 mm FOV, XN Rugose coral in Paleozoic Bangor Limestone (Alabama) Coral skeletons Brecciation (post-lithification) Ferroan calcite cement 2.5 mm FOV, PPL, Stained Litharenite (Cretaceous, Alberta) Chert Rock Frag.
