A broad geologic study of the structure and ore deposits of the Wisconsin-Illinois-Iowa zinc-lead district (fig. 1) was begun by the U.S. Geological Survey in 1942. The main object of the present program is to delineate the areas favorable to future exploration for zinc-lead ore deposits. As part of the program the Sinsinawa River area in southeastern Grant County, Wis., was selected for a detailed geologic study. This study was made in cooperation with the Wisconsin Geological and Natural History Survey.
