Lithic arkose
The specific roadcut is 11 m long, 5 m wide and 6 m high and consists of Upper Triassic lithic arkose of the Xujiahe Formation. The rockmass has two primary discontinuity sets, one of which ...A feldspar-rich sandstone is called an arkose. Lithic rich sandstones are called litharenites. Further subdivisions are shown in the diagram. If the rock has between 10 and 50% clay matrix, the rock is called a wacke. Quartz wackes have predominantly quartz surrounded by a mud or clay matrix. In a feldspathic wacke, feldspar is more abundant ...The results show that the sandstone of fine-grained sediments of Chang 7 oil layer is dominated by arkose with a minor number of lithic arkose.

Sandstone of the "Trabuco" is a lithic arkose containing angular quartz and fresh subhedral feldspars suggestive of derivation from quartz monzonite basement terrane. The general lithofacies trends of the "Chico" formation are: (1) upper fan to middle fan from east to west, and (2) slope to shelf from bottom to top.The sandstone can be classified according to the Folk's classification. If a sandstone has above 90% quartz so it will be quartz arenite. If it has more feldspar it will be arkose and will increasing lithics and feldspar, changes from arkose to lithic arkose and then to feldspathic litharenite. Same is the case with quartz and lithic fragments.... lithic arenite sandstones. The feldspathic sandstone belongs to this ...

Arkose ( / ˈɑːrkoʊs, - koʊz /) 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. Quartz is commonly the dominant mineral component, and some mica is often present.
