Phanerozoic Evolution of Sedimentary Basins in the Uinta-Piceance Basin Region, Northwestern Colorado and Northeastern Utah (Chapter FF)

摘要

The Uinta-Piceance basin region of northwestern Colorado and northeastern Utah has occupied an intraplate geologic setting throughout Phanerozoic time and is mostly underlain by Phanerozoic strata that were deposited over a heterogeneous Precambrian basement. Six phases of Phanerozoic basin evolution are recognized, each of which was initiated by a pulse of rapid subsidence that is correlated with a tectonic event driven by interactions on adjacent plate margins. During the six of Phanerozoic basin evolution, deposition of specific facies was dependent on subsidence rate, sediment supply, eustasy, and climate.
