Importance Of Unconformities To Oil Occurrence In Montana, Robert E. Evenson Jun 1950

Importance Of Unconformities To Oil Occurrence In Montana, Robert E. Evenson

Bachelors Theses and Reports, 1928 - 1970

Although the majority of geologic structures in Montana have been tested in the search for petroleum, only a few have been found to contain commercial quantities of either oil or gas, and with each successive dry hole, producers are becoming more and more wary of investing capital in new wells located on structural features alone. It is apparent that if new oil and gas fields are to be found in Montana, exploration must be done on the basis of someĀ­thing other than structure, or combined with structure.


Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick Jun 1950

Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick

Bachelors Theses and Reports, 1928 - 1970

This paper, a study of the fauna of the Pilgrim formation at South Boulder Creek in southwestern Montana, represents a laboratory study of the fossil specimens collected by Dr. Alvin Hanson during the summer of 1949. The scope of investigation includes identification and classification of the faunas, their stratigraphic relationship and zonal subdivisions.


Structure Of Southwestern Montana, Donald W. Levandowski May 1950

Structure Of Southwestern Montana, Donald W. Levandowski

Bachelors Theses and Reports, 1928 - 1970

Intrusions of granitic rocks on a large scale are commonly found in the central part of folded mountain systems. Igneous rocks, intrusive and extrusive, are widespread in the mountains of southwestern Montana. An examination of the structural pattern of this area indicates that the fold trends form a radial pattern. How and why this pattern formed and its relation to the igneous activity in the area have not yet been discussed in the literature.
