Book excerpt: Excerpt from Refractory Clay Deposits of South-Central Colorado A field investigation of the Occurrences Of high-alumina refractory clay in the Cretaceous formations Of south-central Colorado was made by the writer for the Geological Survey between November 1943 and July 1944. At this time the refractory clay was considered as a pos sible source Of alumina, from which metallic aluminum might be recovered, and the primary purpose Of the work was to estimate the probable recoverable tonnage of high-alumina flint clay averaging 35 percent or more in alumina. However, clays are not yet mined anywhere in the United States as ores of metallic aluminum and the present commercial value of the clays described in this report depends primarily on their refractoriness. The field work was concentrated around the active mining districts, and in addition a reconnaissance study Of the clay - bearing formations over most Of the area was made in search of additional deposits Of the flint clay. In the latter part Of the summer Of 1950, the area was revisited for three weeks in order to bring the information on mining up to date and to restudy certain details Of the stratigraphy.
