Earth history final 2

accretion of an island arc onto North America - Devonian

caused by stress from Pangaea - Pennsylvanian to Permian

plates attaching- formed faults and clastic wedges on top of the Antler orogeny - Triassic

subduction resulted in continental arcs forming the Sierra-Nevada batholiths - Jurassic

thrust faults eastward in backarc zone- shallow reverse faults in sedimentary layers - Jurassic to Early Cret

• Pre-Cambrian basement rock uplifts
• Late Cret.

extensional stress creates plateaus - Miocene
