Available in PDF, EPUB and Kindle. Book excerpt: The Calico Hills area in the southwestern part of the Nevada Test Site, Nye County, Nevada, exposes a core of pre-Tertiary rocks surrounded by middle Miocene volcanic strata. This map portrays the very complex relationships among the pre-Tertiary stratigraphic units of the region. The Devonian and Mississippian rocks of the Calico Hills are distinct from age-equivalent carbonate-shelf or submarine-fan strata in other parts of the Nevada Test Site. The Calico Hills strata are interpreted to have been deposited beyond the continental shelf edge from alternating silicic and carbonate clastic sources. Structures of the Calico Hills area record the compounded effects of: (1) eastward-directed, foreland-vergent thrusting; (2) younger folds, kink zones, and thrusts formed by hinterland-vergent deformation toward northwesterly and northerly directions; and (3) low-angle normal faults that displaced blocks of Middle Paleozoic carbonate strata across the contractionally deformed terrane. All of these structures are older than any of the middle Miocene volcanic rocks that were erupted across the Calico Hills.

Available in PDF, EPUB and Kindle. Book excerpt: The Mine Mountain area is a small range of hills on the west side of the central Yucca Flat basin on the Nevada Test Site, Nye County, Nevada. This map portrays the very complex relationships among the pre-Tertiary stratigraphic units of the region. Rocks and structures of the Mine Mountain area record the compounded effects of: (1) eastward-directed, foreland-vergent thrusting; (2) younger folds and thrusts formed by hinterland vergence in a general westerly direction; and (3) low-angle normal faulting formed by extension along a northeast-southwest trend. All of these structures are older than the oldest middle Miocene volcanic rocks that were deposited on the flanks of the Mine Mountain terrane. High-angle faults that post-date these volcanic rocks locally show displacements of several hundred meters, but do not strongly affect patterns in the pre-Tertiary rocks.

This book was released on 1998 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lateral and vertical distributions of Proterozoic and Paleozoic sedimentary rocks in southern Nevada are the combined products of original stratigraphic relationships and post-depositional faults and folds. This map compilation shows the distribution of the pre-Tertiary rocks in the region including and surrounding the Nevada Test Site. It is based on considerable new evidence from detailed geologic mapping, biostratigraphic control, sedimentological analysis, and a review of regional map relationships. Proterozoic and Paleozoic rocks of the region record paleogeographic transitions between continental shelf depositional environments on the east and deeper-water slope-facies depositional environments on the west. Middle Devonian and Mississippian sequences, in particular, show strong lateral facies variations caused by contemporaneous changes in the western margin of North America during the Antler orogeny. Sections of rock that were originally deposited in widely separated facies localities presently lie in close proximity. These spatial relationships chiefly result from major east- and southeast-directed thrusts that deformed the region in Permian or later time. Somewhat younger contractional structures are identified within two irregular zones that traverse the region. These folds and thrusts typically verge toward the west and northwest and overprint the relatively simple pattern of the older contractional terranes. Local structural complications are significant near these younger structures due to the opposing vergence and due to irregularities in the previously folded and faulted crustal section. Structural and stratigraphic discontinuities are identified on opposing sides of two north-trending fault zones in the central part of the compilation region north of Yucca Flat. The origin and significance of these zones are enigmatic because they are largely covered b Tertiary and younger deposits. These faults most likely results from significant lateral offset, most likely in the sinistral sense. Low-angle normal faults that are at least older than Oligocene, and may pre-date Late Cretaceous time are also present in the region. These faults are shown to locally displace blocks of pre-Tertiary rock by several kilometers. However, none of these structures can be traced for significant distances beyond its outcrop extent, and the inference is made that they do not exert regional influence on the distribution of pre-Tertiary rocks. The extensional strain accommodated by these low-angle normal faults appears to be local and highly irregular. 1 plate.

This book was released on 1989 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 186. The Nevada Test Site (NTS) was established on December 18, 1950, to provide an area for continental testing of nuclear devices. In January of 1951, testing began with an airdrop into Frenchman Flat in conjunction with Operation Ranger. In addition to airdrops, above ground testing included surface detonations, tower shots, and balloon suspensions. Underground testing began in 1957, and since 1963, all events have been buried in large-diameter drill holes or tunnels. Geologists from the U.S. Geological Survey (USGS) mapped much of the NTS region between 1960 and 1965. These maps formed the basis for subsequent studies by Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Sandia National Laboratories, and the USGS. A good understanding of the stratigraphy, structure, geochemistry, and physical properties of the rocks is essential for containment of underground nuclear tests. Many of the recent geologic studies at NTS, particularly in Yucca Flat, Pahute Mesa, and Mid Valley, are aimed at understanding subsurface geology to help ensure complete containment. The potential nuclear waste site at Yucca Mountain is located approximately 100 miles (160 km) by road northwest of Las Vegas, Nevada, and situated on land controlled by three Federal agencies; the Bureau of Land Management, the Department of Energy (Nevada Test Site), and the U.S. Air Force (Nellis Air Force Range).
