Title: Late Neogene-Quaternary left slip on N-striking faults, SE Nevada-SW Utah area: An event distinct from Miocene WSW-directed major extension

Abstract

Much strike-slip faulting, on [approximately]NW-striking dextral and [approximately]NE-striking sinistral faults, was synchronous with large-magnitude extension in the Great Basin (e.g., Wernicke and others 1988, GSA Bulletin). However, in the SE Nevada area major Miocene extension ([approximately]100 km WSW extension) was followed by sinistral slip on several [approximately]N-striking faults. These faults have moderate to steep dips, cut all structures that intersect them, control range-scale topography, are typically >10 km long, and some cut Pliocene-Quaternary deposits. These data conflict with the idea that the N-striking sinistral faults were coeval with Miocene-Recent normal faulting that produced only minor extension in the SE Nevada area ([approximately]10%; Anderson and Barnhard, ref. above). However, they are consistent with seismic (Bohannon and others in press, GSA Bulletin) and numerous geologic studies documenting large-magnitude Miocene extension, and also suggest a Pliocene-Recent episode of sinistral slip on N-trending faults coeval with slowed Pliocene-Recent extension.
