Granitic rocks of 1760-Ma age group (WIXga;0)

Granitic rocks of 1760-Ma age group

In northern Wisconsin, granite to granodiorite of varied texture. In southern Wisconsin (not mapped separately), red to pink alkali-feldspar granophyric granite associated with rhyolites of both peraluminous and metaluminous affinities (unit Xr of Marshfield terrane).
