Ice flow direction during late Paleozoic glaciation in western Paranل Basin, Brazil

The recent discovery of ice-striated surfaces associated with the late Paleozoic Aquidauana Formation suggests that glaciers coming from southwest Africa reached westernmost parts of the Paranل Basin in central Brazil. Abrasion features were developed by glaciers moving from SSE towards NNW, mainly on an unconsolidated bed. These records expand to about 1,050,000 km2, the coverage of the late Paleozoic glaciation in the region of the Paranل Basin in Western Gondwana.
