Neogene sedimentary rocks, largely lacustrine and fluvial, were deposited in many areas of western Nevada and easternmost California, more or less continuously from ~12 Ma-3 Ma. These sediments were deposited on a surface of moderate primary relief developed on underlying Miocene volcanic rocks, and depositional facies are laterally variable, with sedimentation beginning and ending at different times in different areas. About 3 Ma, the basin system began to break up structurally, with strike-slip, oblique-slip and normal faulting, and local uplift. Modern topography inverts many original highs and lows. Stratigraphy and structure of Neogene strata document the progressive shut-down of the Neogene Cascade arc, the evolution of transtensional tectonics in the Walker Lane, and the encroachment of extensional faulting into the eastern Sierra Nevada.
Figures & Tables
Great Basin and Sierra Nevada, the second volume of the Geological Society of America Field Guide Series, focuses on the dynamic and spectacular geology of this region, providing the inspiring backdrop for the 2000 GSA Annual Meeting in Reno. This volume gives complete coverage of field trips held in conjunction with that meeting, and contains 20 chapters organized into three sections. The first section consists of 16 chapters arranged in geochronological order, beginning with the active tectonics of Lake Tahoe and the historical surface faulting and paleoseismicity of the central Nevada seismic belt, and ending with the Neoproterozoic glacial record of Death Valley. In between are chapters dealing with Basin and Range extension, Eocene magmatism, Mesozoic plutonism in the Sierra Nevada, Paleozoic subduction, and Ordovician stratigraphy, to name a few. The second section covers the geology of the Nevada Test Site and the nuclear-waste repository at Yucca Mountain. The last section is an invited field guide from the 1999 GSA Cordilleran Section meeting that covers the wines and geology of Napa Valley, California. Overall, Great Basin and Sierra Nevada is a comprehensive compilation of new and exciting research on this amazingly diverse region, with well-crafted guides to field localities of special interest. Full-color plates in some chapters make this guide an especially appealing and useful volume.
