Stratigraphy of the wisconsin range, horlick mountains, antarctica.
The Wisconsin Range consists of a basement complex of granitic and metamorphic rocks unconformably overlain by about 550 meters of Upper Paleozoic sedimentary rocks. The base of the Upper Paleozoic succession is composed of the Buckeye formation, a tillite, which varies in thickness from 80 to more than 140 meters. Overlying the Buckeye formation are the Weaver and Queen Maud formations, with a combined thickness of about 455 meters, characterized by a prolific Glossopteris flora, indicative of a Permian age.
