Fifty Years of Death Valley Research A volume in honor of Lauren Wright and Bennie Troxel

About this book

Wright and Troxel's research in Death Valley covers a wide variety of subjects including stratigraphy, structure, regional tectonics, Quaternary geology, and mineral resources. Their diversity in research is reflected in this volume. The first two chapters add stratigraphic and #13C data to the constantly growing volume of literature on Neoproterozoic global glaciation and the Snowball Earth theory. The next seven chapters are nearly Equally divided between late Paleozoic thrust faulting, middle Cenozoic extensional tectonics, and magmatism. Note that the three chapters on extensional tectonics represent the latest contributions in a continuum of research since Wright and Troxel published their landmark paper, Shallow fault interpretation of Basin and Range structure, in 1973. The next four chapters describe the late Neogene to Holocene geology and geomorphology of Death Valley, research topics very dear to Wright and Troxel in the last 10 years. The last chapter describes the lead-zinc deposits of the southern Basin and Ranges, including the Death Valley region.
