Abstract

Crescentic gouges and lunate fractures with main fractures dipping upstream and crescentic fractures apparently dipping in the same direction were observed on a glacial pavement developed in the glacial sequence of the Tubarao Group. Direction of upper Paleozoic ice movement in the area was toward N. 60° W.
