Microscopic Study Of Montana Silver Ores., Edwin Johnson
Microscopic Study Of Montana Silver Ores., Edwin Johnson
Bachelors Theses and Reports, 1928 - 1970
A microscopic investigation of the Montana silver minerals was conducted. This study consisted mainly of identifying the silver and silver-bearing minerals and of determining their paragenetic relationships. The increasing amount of research in which the reflecting microscope is employed is evidence of the great value of this method of approach in the solution of problems of paragenesis of the opaque minerals.

The Geology Of Lost Creek Canyon With Special Reference To Igneous Activity, John Kolesar
Bachelors Theses and Reports, 1928 - 1970
This investigation was undertaken primarily as a problem in geologic mapping, coupled with a study of stratigraphy, glaciation, igneous phenomena, and structure. The area is admirably suited to a study of geology and geologic events. Because it is small in extent, the area was studied in some detail during the time which was devoted to field work. The record of igneous activity of past geological ages is remarkably well exposed, since Lost Creek Canyon was carved through the roof of a stock or batholith by the glaciers of the Pleistocene epoch.
