Clarksville soils have control sections with less than 35 percent sand content coarser than very fine and are dominated by chert gravel. GEOGRAPHIC SETTING: The Coulstone soils are on steep side slopes and narrow ridgetops. They formed in a thick regolith from acid sandstones with lenses ...In stream banks, the Mounds Gravel is overlain by the Metropolis Formation (consisting of orange and gray silty sand and weathered brown chert gravel [Nelson et al., 1999, Nelson et al., 2002]) or loess. Near the confluence of the creeks, the Mounds Gravel has been reworked by modern fluvial processes, as indicated by a lack of cementation.
In the finer-grained rocks, mineralogical composition is often difficult to determine and interpret. Suppose we look at a sandstone with a hand lens (Figure 7.71). Quartz, and perhaps K-feldspar, may be easy to find. However, lithic fragments can be confusing and small grains of chert or magnetite may be impossible to identify.Commonly the gravel has been derived from glacial or periglacial deposits, as on the north coast of Alaska and the southern shores of the Baltic Sea, whereas Chesil Beach is an accumulation of flint and chert gravel derived from the Cretaceous rocks of southern England.Jan 8, 2020 · Chert is widespread, but not widely known by the public as a distinct rock type. Chert has four diagnostic features: the waxy luster, a conchoidal (shell-shaped) fracture of the silica mineral chalcedony that composes it, a hardness of seven on the Mohs scale, and a smooth (non-clastic) sedimentary texture. The cherts and shales used in this investigation were obtained by hand picking from glacial gravel deposits widely scattered throughout the State of Indiana. In this way six chert and five shale samples, constituting as widely divergent a group of cherts and shales as could be found in Indiana, were obtained. The geographic locations of
Conglomerate ( / kənˈɡlɒmərɪt /) is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel -size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically ...Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges.…

Thinly in terbedded glauconitic sands and clays of the unconformably overlying McShan Formation occupy the uppermost portions of the exposure. The western lithofacies occupies the great majority (over Stream-laid deposits of gravel, sand, silt, and clay as much as 40 feet thick occupy the valleys of Elk and Fall Rivers. Thinner accumulations partly fill the valleys of smaller streams. In the larger valleys coarse material, predominantly chert, limestone, and sandstone gravel, commonly is found in a lower zone ranging from a fraction of an ...
