This book was released on 2018-06-30 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geologic mapping and interpretation of Landsat TM imagery has filled in a significant gap in the geologic database for southwestern Arizona and southeastern California. The new data acquired, along with interpretation of existing data, forms the basis for a proposed reconstruction of late Tertiary faults in these regions. This reconstruction integrates available geological and geophysical data to define the eastern limit of deformation related to the San Andreas fault, and has significant implications for other recently proposed reconstructions of Tertiary deformation in the region. This progress in interpreting deformation during the last 10 Ma in the region forms a foundation for developing and testing models of older deformation in this region, including the initiation of San Andreas fault system, and the interaction of Early Miocene extension in the Basin and Range with the evolving San Andreas system.

This book was released on 2013 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Searles Valley region of southeastern California exhibits a series of northeasterly trending folds that are anomalously oriented when viewed in the context of the current regional stress field, where the principal compressive stress is oriented from the northeast and southwest. This region also marks a complex zone of deformation, as the Blackwater fault of the Eastern California Shear Zone (ECSZ) appears to terminate at its intersection with the Browns Valley/Ranch fault zone, 5 km south of the Garlock fault. The presence of the northeasterly trending Christmas Canyon anticline near the junction of these three fault systems has led to the inference that regional compression directed from the northwest and southeast may have occurred during the last 640,000 years. To assess the style of deformation associated with the interaction of these three fault zones, a geologic survey consisting of geologic mapping, remote sensing and absolute-dating techniques was conducted within the northeastern Lava Mountains, immediately south of the Garlock fault. The study area, informally designated as western Christmas Canyon, exhibits a series of northeasterly trending structures that have deformed and offset lacustrine deposits of the middle Pleistocene Christmas Canyon Formation. These northeasterly striking faults, exhibit displacements suggestive of sinistral shear, and are oriented on average 22 degrees counterclockwise to the trace of the Garlock fault in southern Searles Valley. The orientation and mode of deformation attributed to these faults implies that they may have formed as Riedel shears to the sinistral Garlock fault zone, and thus likely formed during a period of northeast-southwest directed regional compression. Conversely, a single northeast-trending synclinal structure within western Christmas Canyon implies regional compression nearly orthogonal to the adequate orientation for driving sinistral shear along the Garlock fault zone. The results obtained from the geologic survey of the western Christmas Canyon region imply that the Garlock fault has sinistrally offset two alluvial fan surfaces from their source drainage during the late Holocene, and that a period of northwest-southeast directed compression most likely did not occur since the deposition of the middle Pleistocene Christmas Canyon Formation. As a result, the formation of northeasterly trending folds within the Christmas Canyon Formation is inferred to be attributed to deformation associated with slip along Riedel shears of the Garlock fault zone, or as a result of distributed deformation associated with the termination of northwesterly striking dextral faults of the Eastern California Shear zone or P' shears to the Garlock fault.

This book was released on 2013-10-24 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book is a must-read for researchers interested in extensional tectonics in general and the Neogene tectonics of the Basin and Range in particular, because it challenges, on the basis of more than 50 years of field studies, the existing paradigm of province-wide uniformly large extension and replaces it with a model integrating extension with extension-normal shortening-both as primary strains. The first chapter takes the reader on two journeys southwestward from central Utah through the Lake Mead area: the first to emphasize the lack of uniformly distributed or integrated extension and the second to highlight left-lateral shear at 13 localities along the east margin of the Basin and Range that is kinematically compatible with right-lateral shear along the west margin. The compatibility provides a basis for understanding the extreme Neogene tectonics of the Lake Mead area. The second chapter summarizes multifaceted field evidence from the well-studied eastern Lake Mead area as a focused example of the need for a complete revision of the extensional paradigm." -- Publisher's description.

This book was released on 2018-07-11 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A paleogeographic reconstruction of southeastern California and southwestern Arizona at 10 Ma was made based on available geologic and geophysical data. Clockwise rotation of 39 deg was reconstructed in the eastern Transverse Ranges, consistent with paleomagnetic data from late Miocene volcanic rocks, and with slip estimates for left-lateral faults within the eastern Transverse Ranges and NW-trending right lateral faults in the Mojave Desert. This domain of rotated rocks is bounded by the Pinto Mountain fault on the north. In the absence of evidence for rotation of the San Bernardino Mountains or for significant right slip faults within the San Bernardino Mountains, the model requires that the late Miocene Pinto Mountain fault become a thrust fault gaining displacement to the west. The Squaw Peak thrust system of Meisling and Weldon may be a western continuation of this fault system. The Sheep Hole fault bounds the rotating domain on the east. East of this fault an array of NW-trending right slip faults and south-trending extensional transfer zones has produced a basin and range physiography while accumulating up to 14 km of right slip. This maximum is significantly less than the 37.5 km of right slip required in this region by a recent reconstruction of the central Mojave Desert. Geologic relations along the southern boundary of the rotating domain are poorly known, but this boundary is interpreted to involve a series of curved strike slip faults and non-coaxial extension, bounded on the southeast by the Mammoth Wash and related faults in the eastern Chocolate Mountains. Available constraints on timing suggest that Quaternary movement on the Pinto Mountain and nearby faults is unrelated to the rotation of the eastern Transverse Ranges, and was preceded by a hiatus during part of Pliocene time which followed the deformation producing the rotation. The reconstructed Clemens Well fault in the Orocopia Mountains, proposed as a major early Miocene strand of the San Andr...
