Mineral Economics Brief - Illinois State Geological Survey

Twenty-nine reports were prepared in this series between 1961 and 1971. These reports provided information regarding all aspects of the economics of the mineral industry in Illinois for the time period noted in each edition, including locations of minerals, production data, and directories of producers. After the publication of edition number 29, the Mineral Economics Briefs series was combined with the Industrial Mineral Notes series to form the Illinois Mineral Notes series. No. 1 (1961) to No. 29 (1971). See Illinois Minerals.
