dc.description.abstractThe Great Valley Group has long been considered to be the forearc basin of a traditional convergent margin assemblage along with the Franciscan Complex (subduction complex), and Sierra Nevada batholith (magmatic arc), with negligible translation between them. However, evidence has been provided in previous studies suggesting that the Great Valley Group was deposited in a basin that was translated north in the Cretaceous. The purpose of this project is to use new petrologic and detrital zircon data to test the translational model. New petrographic and detrital zircon data shows that the Klamath GVG and the Coast Range GVG are distinct from each other. Comparing the zircon data by depositional age shows the Coast Range GVG and Klamath GVG as dissimilar in the Neocomain, becoming more alike in the mid-Cretaceous, and being quite similar in the Cenomanian to Turonian. This data supports the idea that the Coast Range GVG and Klamath GVG were deposited apart from each other and the Coast Range GVG was translated northward along strike-slip faults until it was adjacent to the Klamath GVG in the Cenomanian to Turonian.
