The Wichita Granite Group are medium- to fine-grained alkali-feldspar granite rocks of Cambrian age exposed in the Wichita Mountains of southwestern Oklahoma. All exhibit a reddish color imparted by small desseminated hematite grains. They are broken into several mappable units based on composition, texture, and cross-cutting relationships [1]. Exposures form isolated peaks and rocky uplands that support only thin soils that locally thicken within fractures and potholes.
The individual lithostratigraphic units were largely defined By M.C. Gilbert [1], and are presented in terms of their outcrop region and relative age (younger to older). Oklahoma state highway 54 is the approximate division for the two geographic provinces.
In general the Wichita Granite group has been exploited for fill and road metal. More extensive quarrying for dimension stone is confined to the Reformatory Granite in and around the town of Granite.
