The Eruptive and Sedimentary Rocks on Pigeon Point, Minnesota, and Their Contact Phenomena

From preface: The preparation of this paper is due to the fact that the eruptive rocks occurring on Pigeon point, Minnesota, may be taken as types of similar eruptives found so widely spread over the Huronian and Keweenawan areas surrounding Lake Superior, and to the peculiar nature of the alteration these have superinduced in the fragmental rocks through which they have broken.

Pre-Cambrian Rocks of the Lake Superior Region: A Review of Newly Discovered Geologic Features, with a Revised Geologic Map (open access)

Pre-Cambrian Rocks of the Lake Superior Region: A Review of Newly Discovered Geologic Features, with a Revised Geologic Map

From abstract: Detailed knowledge of the geology of the pre-Cambrian rocks of the Lake Superior region has been greatly augmented since the publication of Monograph 52 by the United States Geological Survey in 1911. The authors have attempted in the present report to assemble as much of this new information as possible, and to give the reader a birdseye view of the geology as seen in the light of all studies made there up to the present time. Detailed descriptions are not presented, and the emphasis is placed upon the major problems of correlation. A revised map of the region, with cross sections, accompanies the report, bringing up to date a knowledge of the areal geology of the region, which otherwise could be gained only by consulting some 150 maps contained in almost as many separate local reports, many of which are unpublished.
