  • fluorspar deposits study - woningbedrijfwarnsveld.nl

    A study of the Kentucky-Illinois fluorspar deposits was begun in 1942 by the TJ. S. Geological Survey because of the increased demand for fluorspar during World War II. Before a specific program for fieldwork was planned, the Kentucky-Illinois field was visited in June 1942 by L. W. Currier and James Steele Williams, of the U. S. Geo­
