The Geology of the Kimberley Division, Western Australia and of an adjacent area of the Northern Territory

Abstract

This paper describes the geology of an area of approximately 110,000 sq. miles in the Kimberley District of northern Western Australia, and of an area of approximately 40,000 sq. miles in the adjacent portion of the Northern Territory; it presents the information gained by the author during a period of five years (1953-57) spent in field and laboratory work in the course of a survey carried out by The Broken Hill Proprietary Co. Ltd. Field work was chiefly concentrated on Lower Cambrian and Pre-cambrian rocks, and these successions have been subdivided and described in some detail; a summary of the post-Lower Cambrian geology is also given, partly based on the author;s field observations, but chiefly derived from the work of others, notably Traves, Rattigan, Guppy, Lindner, and others of the Bureau of Mineral Resources. The regional geological map with the paper is the most comprehensive so far prepared for the region.
