Rapid deposition in turbidity currents produces its graywacke (GRAY- wacky) variety, while disintegration of granite without appreciable chemical weathering produces the feldspar-rich type, arkose.
Laisvall type deposits hosted by this lithology serve as an evolutionary link between Mississippi Valley Type lead-zinc and Stratiform copper deposits, and another economically important variety hosts roll-front uranium-vanadium deposits. Rapid deposition in turbidity currents produces its graywacke (GRAY- wacky) variety, while disintegration of granite without appreciable chemical weathering produces the feldspar-rich type, arkose. Cross-bedding and rippling are two common formations in this rock type whose textural groups are the wackes (WACK-eez) and arenites. For ten points, name this sedimentary rock second in abundance to shale, which can form by lithification of dunes.
