3-28-12 How do we determine a sequence of events for rock layers?. Do Now: What is original horizontality, superposition, and uniformitarianism ? What is contact metamorphism? Take out your review book, a piece of paper, and a PENCIL HW: R&H 278-282 A&E 1-20. Exceptions to Superposition.
HW: R&H 278-282 A&E 1-20
Inclusion – a body of older rock inside an intrusion which did not melt when the intrusion formed
Cross Cutting –Cross cuts are always younger then the rock they cut through. (Faults, Intrusions, Veins)
Unconformities - buried erosional surfaces which show that there are rocks missing (or a gap) from the record.
HW: Finish Matching Rock Layers Lab.
HW: Complete all questions in Topic 13.
