Economic Talc Deposits Of Montana And Related Firing Problems, Charles J. Lyden
Economic Talc Deposits Of Montana And Related Firing Problems, Charles J. Lyden
Bachelors Theses and Reports, 1928 - 1970
This thesis has to do with a study of the production of talc in Montana, describing the local geology of each deposit, and a description of the laboratory tests that were made on various grades of Montana talc in an attempt to determine why some grades of talc can be burned in solid forms while others must be ground, mixed with a binder and molded.
Helena And Ennis Talc Deposits, Howard N. Anderson
Helena And Ennis Talc Deposits, Howard N. Anderson
Bachelors Theses and Reports, 1928 - 1970
The purpose of this report is to collect geologic data concerning two Montana talc occurrences at Helena and Ennis and to offer some explanation as to their origin. The two deposits cited are in somewhat similar lithologic settings and both possess the same mineralogical and structural features. Because of this similarity only the Helena deposit is covered in detail.
