DNR Report 280: 1991; Regional Survey of Buried Glacial Drift, Saprolite and Precambrian Bedrock in Lake of the Woods County, Minnesota

Project Funded by the Minerals Coordinating Committee Through the Mineral Diversification Program

Background extracted from Report 280, page 1:

BACKGROUND  This survey of part of Lake of the Woods County (the Baudette area) in northern Minnesota represents a westward expansion of the deep overburden characterization (glacial till sampling) program begun by the Department of Natural Resources in 1985. The goals of the program are to detect regional-scale anomalies of gold and other metals in the glacial overburden, and to develop the stratigraphic framework for understanding those anomalies. The Baudette area, near Lake of the Woods on the Canadian border, is covered by deep glacial overburden (> 100 feet), and is underlain by an attractive, but relatively unexplored, gold terrane made up of structurally-deformed, volcanic associated rocks of the Wabigoon granite greenstone belt. The deep overburden hides the bedrock and hinders mineral potential evaluation of state lands.
