The significance of a glacial erratic from the Chatham Rise, east of New Zealand

Abstract

The recognition of an undoubted glacial erratic within a heterogeneous collection of rock fragments dredged from the Chatham Rise raises the possibility of extensive and long-continued deposition of rock debris by drifting icebergs in this area. The specimen is a red feldspathic sandstone of a type not known in New Zealand but showing some resemblance to rocks of the Beacon Sandstone of Antarctica.
