The Eruptive and Sedimentary Rocks on Pigeon Point, Minnesota, and Their Contact Phenomena (open access)

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.
