The Antler Overlap Sequence in Nevada: The Ancestral Rocky Mountain Period Timeframe

During the Ancestral Rocky Mountain period between Late Pennsylvanian to Early Permian time, Nevada was subjected to a different set of geological conditions due to it's closer proximity to the western and southwestern subduction zones off the Laurentian margin. While the interior parts of the western continental states of Idaho, Utah, Wyoming, and Colorado were subjected to Ancestral Rocky Mountain uplift and basin sedimentary tectonics, Nevada was subjected to basin and range type extension associated with faulting, folding, uplift, and basin development. Parts of the northeastern section of Nevada was exposed to Ancestral Rocky Mountain influences. Nevada's Ancestral Rocky Mountain period occurred between the Antler and Sonoma orogenies, placing it's Pennsylvanian and Permian period in a sedimentary overlapping sequence. This book attempts to assemble a geologic treatise focusing on the Antler Overlap Sequence (AOS) that occurred in the state during the Ancestral Rocky Mountain time frame.Chapter 1 describes the tectonic domains of Nevada from a paleo-geographic perspective.Chapter 2 presents Late Paleozoic tectonics.Chapter 3 provides stratigraphic and structural details on the Antler Peak Quadrangle in Humboldt and Lander Counties.Chapter 4 briefly describes the Humboldt Orogeny influenced by the Ancestral Rocky Mountains.Chapter 5 presents the geology of the Toiyabe Range.Chapter 6 presents Late Paleozoic deformation in the Osgood Mountains.Chapter 7 concludes the book with a discussion of the Ely-Bird Spring Basin, Wood River, Oquirrh basins, the Wyoming Shelf, and the timing of basin initiation.
