Pure and shear-enhanced compaction bands in Aztec Sandstone

The Aztec Sandstone is a well-sorted, cross-bedded, and medium-grained sandstone deposited in a backarc setting (Marzolf, 1990). The Baseline Sandstone is a syntectonic molasse sequence of sandstone and conglomerate deposited in front of the Sevier thrust complex (Aschoff and Schmitt, 2008). Our detailed field descriptions of deformation bands ...

Valley of Fire State Park | State Parks

Valley of Fire consists of bright red Aztec sandstone outcrops nestled in gray and tan limestone mountains. The sandstone is from the Jurassic period and is the remnant of the sand left behind by the wind after inland seas subsided and the land rose. Early man moved into southern Nevada as far back as 11,000 years ago.

still evident in the Aztec sandstone found in Red Rock Canyon National Conservation Area (NCA), Valley of Fire State Park, and Lake Mead NRA. It continues into Arizona and Utah where it is called Navajo sandstone. Red, beige, and even white, this sandstone has a propensity for fanciful erosion by wind and water. Spectacular arches can be formed.

Millstone - Wikipedia

Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones.. Millstones come in pairs: a stationary base with a convex rim known as the bedstone (or nether millstone) and a concave-rimmed runner stone that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action ...

Aztec Sandstone - Wikiwand

The Aztec Sandstone is an Early Jurassic geological formation of primarily eolian sand from which fossil pterosaur tracks have been recovered.[4] The formation is exposed in the Mojave Desert of Arizona, California and Nevada.

Sedimentology of an ancient erg margin: the Lower Jurassic Aztec ...

The Lower Jurassic Aztec Sandstone is an aeolian-deposited quartzose sandstone that represents the western margin of the southerly-migrating Navajo-Nugget sand sea (or erg). Vertical and lateral facies relations suggest that the erg margin encroached upon volcanic highlands, alluvial fan, wadi and sabkha environments.

Hermit Formation - Wikipedia

The Permian Hermit Formation, also known as the Hermit Shale, is a nonresistant unit that is composed of slope-forming reddish brown siltstone, mudstone, and very fine-grained sandstone.Within the Grand Canyon region, the upper part of the Hermit Formation contains red and white, massive, calcareous sandstone and siltstone beds that exhibit low-angle cross-bedding.

Geology of Red Rock Canyon - Bureau of Land Management

sediments and eventually cemented into sandstone by iron oxide with some calcium carbonate. This formation, known locally as the Aztec Sandstone, is quite hard and forms the prominent cliffs of the Red Rock escarpment. Exposure to the atmosphere led to the iron minerals in some areas to oxidize, giving the rocks their red and orange colors.

What's Out There? - Friends of Nevada Wilderness

During the Triassic, rivers piled sand and mud atop the limestone and gypsum. As the climate dried out during the Jurassic, sand dunes blew across the landscape. Those dunes were later buried by younger sediments, cementing the loose sand to form the Aztec Sandstone.

Petrophysical Constraints on Deformation Styles in Aztec Sandstone ...

The Jurassic Aztec sandstone is an eolian sandstone correlated to the more widespread Navajo sandstone of the Colorado Plateau (BLAKEY, 1989). Composi-tionally, the Aztec sandstone is a feldspathic quartz arenite composed mostly of rounded to well-rounded quartz (‡ 95% detrital quartz). Grain size ranges from 100 to 1000 lm.

Deformation mechanisms - University of Texas at Austin

Deformation mechanisms in granular media. Of interest are mechanisms of deformation localization along deformation bands and joints in sand and sandstone. Deformation bands are planar or curviplanar zones of finite width, usually a few grain diameter in thickness, of deformation. Based on the dominant mode of deformation, we distinguish shear ...
