Wichita Granite Group (OKCAwg;0)

State	Oklahoma
Name	Wichita Granite Group
Geologic age	Phanerozoic \| Paleozoic \| Cambrian-Middle
Original map label	Cwg
Comments	Comments: Probably named for Wichita Mountains of southern OK. Report area is southern Oklahoma, where it is present in (east to west, mostly subsurface): western Jefferson, Cotton, Comanche, Kiowa, and Greer Cos (South Oklahoma folded belt province); Beckham and Washita Cos (Anadarko basin); and Jackson and Harmon Cos (Palo Duro basin). Consists chiefly of perthite leucogranites of various textures representing multiple intrusions, in part having the form of extensive sills 600 to 1,500 ft thick intruding the lower part of the Carlton Rhyolite Group [revised--Carlton is the extrusive equivalent of Wichita], and in part occurring as irregular plutons and sills cutting all other rocks of the "Wichita Province." (Ham, 1963)
