22 lis 2023 · Arkose is a type of sedimentary rock characterized by its high mineral content of feldspar, particularly orthoclase. It is often considered a type of sandstone, but its distinctiveness lies in the abundance of feldspar grains, which typically make up at least 25% of the rock.
Arkose, coarse sandstone (sedimentary rock composed of cemented grains 0.06–2 millimetres [0.0024–0.08 inch] in diameter) primarily made up of quartz and feldspar grains together with small amounts of mica, all moderately well sorted, slightly worn, and loosely cemented with calcite or, less.
Uses. The arcosa does not usually have very interesting uses, however we highlight the following: It can be used as low to medium quality ballast on second and third order highways, on railway tracks, and as a foundation for country houses.
Arkose (/ ˈ ɑːr k oʊ s,-k oʊ z /) or arkosic sandstone [1] is a detrital sedimentary rock, specifically a type of sandstone containing at least 25% feldspar. [2] [3] Arkosic sand is sand that is similarly rich in feldspar, and thus the potential precursor of arkose.
Arkose sandstone weathers to a grayish and often reddish hue. Because of its properties, arkose sandstone is used in a variety of applications. Because of its high feldspar content, it can be used as a building material or for decorative purposes.
Arkose has been held by different geologists to be significant respectively of several different types of conditions at the time its formation. By Walther,2 for instance, it is considered to be so distinctive of desert formations as to be, next to salt deposits, the most important index of the desert origin of a formation.
