Bedrock in this area consists of Proterozoic to Jurassic igneous and metamorphic rocks that are overlain by Miocene silicic volcanic rocks, subordinate mafic and intermediate volcanic units, and continental calcareous sedimentary rocks (plate 1). Sources of data are shown in Figure 2, rock-unit correlations and relative ages are shown in Figu...
