Arkose is commonly a current-deposited sandstone of continental origin, occurring as a thick, wedge-shaped mass of limited geographic extent (as in a fault trough or a rapidly subsiding basin); it may be strongly cross-bedded and associated with coarse granite-bearing conglomerate, and it may denote an environment of high relief and vigorous erosion of strongly uplifted granitic rocks in which the feldspar … It might seem that an unlimited variety of particles could end up in a sedimentary rock. Quartz is usually the dominant mineral in arkose, but feldspar makes up a significant part of the rock (in some cases feldspar may exceed quartz in content). Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row).
