Item Regional and Local Geologic, Mineralogic, and Geochemical Controls of Industrial Clay Grades in the Minnesota River Valley and the Meridian Aggregates Quarry, St. Cloud, Minnesota(University of Minnesota Duluth, 1991-07) Hauck, Steven A; Heine, John J; Shurr, George W; Toth, Thomas A; Tozer, Mary K; Victory, Denise AThe purpose of this project is to determine the regional and local geological, mineralogical, and geochemical factors that control the distribution and grade of the industrial clays in the Minnesota River Valley (MRV) between Redwood Falls and Fairfax, Minnesota and at the Meridian Aggregates Quarry (MAQ), St. Cloud, Minnesota. These controlling factors fall into three broad categories: 1) bedrock controls - parent rock characteristics; 2) physical controls - faults, paleotopography, etc.; and 3) chemical controls.
