Granite Wash (grant wsh) (geology) Material eroded from granites and re-deposited, forming a sedimentary rock with the same major mineral constituents as the original rock.
Core data shows common Granite Wash mineralogical composition to be: 30-40% Quartz (quartz in sand, igneous fragments, quartz overgrowths) 20-30% Plagioclase Feldspar 10-20% Potassium Feldspar 7-18% Clay, primarily authigenic…
