Oil Shales In Montana, Richard N. Miller Feb 1953

Oil Shales In Montana, Richard N. Miller

Bachelors Theses and Reports, 1928 - 1970

Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.


A Listing Of Montana Invertebrate Fossils And A Bibliography Of Montana Paleontology, Robert G. Ingersoll May 1951

A Listing Of Montana Invertebrate Fossils And A Bibliography Of Montana Paleontology, Robert G. Ingersoll

Bachelors Theses and Reports, 1928 - 1970

The oldest system in which identifiable invertebrate fossils have been found is the Cambrian. The basal Cambrian formation found in Montana is the Flathead sandstone and quartzite of Middle Cambrian age. No fossils have been reported from this formation. Above the Flathead is the Wolsey formation composed of green fissile shale with sandy and limy members. This fossiliferous member of the Middle Cambrian is known in Northwestern Montana as Gordon, and in the Philipsburg quadrangle as the Silver Hill formation.


Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta May 1951

Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta

Bachelors Theses and Reports, 1928 - 1970

The exact upper boundary of the Devonian of Mont­ana has long been a controversy, as is true of the Dev­onian-Mississippian contact in many other localities. In an effort to delimit the upper Devonian, various paleontologic studies have been made, more especially in the southwestern part of the state.


Foraminifera From The Colorado Shale Near Sunburst, Montana, Frank R. Reynolds Jun 1950

Foraminifera From The Colorado Shale Near Sunburst, Montana, Frank R. Reynolds

Bachelors Theses and Reports, 1928 - 1970

One of the many secrets which planet Earth has jealously kept from its inhabitants is the microscopic fossil form known as the foraminifer. It hides in common shale, awaiting the patient and painstaking searcher. In furthering the study of the foraminifera of the Colorado group of for­mations in Northern Montana, the United States Geological Survey has collected several suites of shale samples from the Sunburst Dome, five to ten miles south of the Canadian border and twenty-five miles north of the city of Shelby, Montana.


Geology Of Smoke Hollow Area 8 Miles Southeast Of Deerlodge, Powell County, Montana, Floyd C. Bossard May 1950

Geology Of Smoke Hollow Area 8 Miles Southeast Of Deerlodge, Powell County, Montana, Floyd C. Bossard

Bachelors Theses and Reports, 1928 - 1970

This investigation was undertaken primarily as a problem in geologic mapping. The stratigraphy was studied as to the character, age, and sequence of the geologic formations that are exposed. The conclusions were based principally on the field relationships and lithology because no fossils were found.


The Christensen Sillimanite Deposit Southeast Of Dillon, Montana, Everett O. Bracken Jun 1949

The Christensen Sillimanite Deposit Southeast Of Dillon, Montana, Everett O. Bracken

Bachelors Theses and Reports, 1928 - 1970

The minerals sillimanite, kyanite, andalusite, dumortierite, and topaz comprise a group of minerals whose high alumina content and physical properties are particularly desirable in the manufacture of refractory products. Sillimanite is the least plentiful of the minerals of this group, and for this reason it is not used extensively at the present time. However, it would be very desirable to the refractory industry if a suitable domestic source of supply could be established.


Foraminifera From The Colorado Shale Of North-Central Montana, Higbee G. Williams, David P. Wilson May 1949

Foraminifera From The Colorado Shale Of North-Central Montana, Higbee G. Williams, David P. Wilson

Bachelors Theses and Reports, 1928 - 1970

The use of foraminifera in the determination of geologic age, and in the correlation of strata, is one of the most important techniques in oil field stratigraphic studies. The petroleum industry in many regions relies on these microscopic life forms to determine the positions of oil-bearing horizons and to determine the tops of beds. In northern Montana the Colorado group of strata, a series of about 2,000 feet of dense, dark similar shales, is known to contain foraminifers.


Daibase Sill Comanche County, Oklahoma, Jean A. Hardesty May 1949

Daibase Sill Comanche County, Oklahoma, Jean A. Hardesty

Bachelors Theses and Reports, 1928 - 1970

The mechanics of intrusion and the processes involved are becoming of more and more interest to con­temporary geologists, because most of our mineral deposits are associated with igneous intrusions, and unknown-outcropping deposits are thought to be a thing of the past. If, by studying these pro­cesses, we could understand why some igneous masses are barren, while others of similar composition carry economic mineral deposits, geological prospecting for hidden mineral concentration would see a new era.


Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd Jan 1949

Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd

Bachelors Theses and Reports, 1928 - 1970

Plane table and pacing methods were used in the mapping of the individual areas, but an automobile traverse was used to tie the independent areas into a composite group that would be useful for the entire zone. All land marks, section corners, roads, fence lines, drainage, and geologic features were plotted in the field and later transferred to a master map.


Sandstones Of The Lance And Fort Union Formations, Alan G. Conner May 1948

Sandstones Of The Lance And Fort Union Formations, Alan G. Conner

Bachelors Theses and Reports, 1928 - 1970

The Fort Union and Lance formations are widespread terrestrial sediments exposed in Montana, North Dakota, South Dakota, Wyoming, and Canada. Their stratigraphic position, especially that of the Lance, has long been in doubt, and has provoked much controversy among geologists.


Geology Of The Lost Creek-Modesty Creek Area Deerlodge County, Montana, Howard B. Nickelson, Robert L. Pott May 1948

Geology Of The Lost Creek-Modesty Creek Area Deerlodge County, Montana, Howard B. Nickelson, Robert L. Pott

Bachelors Theses and Reports, 1928 - 1970

In 1915 the United States Geological Survey published a folio by Calkins and Emmons on the geology of the Philipsburg Quadrangle, which ad­joins the area now under study to the west. Geology of this portion of Montana had not been mapped previously; consequently the purpose of this thesis is to make a geological reconnais­sance of the stratigraphy and structure of the area.


Geology And Mineral Deposits Of Idaho: A Summary, Paul B. Bronken May 1947

Geology And Mineral Deposits Of Idaho: A Summary, Paul B. Bronken

Bachelors Theses and Reports, 1928 - 1970

The great diversity on mineral wealth in Idaho establishes it as one of the principle mining states in the union. Mining first began in the state with the discovery of placer gold in the Pierce City district in 1861, and since that date has become one of the leading industries of the state.


Upper Cretaceous Sediment In Montana, Frank J. Frankovich May 1947

Upper Cretaceous Sediment In Montana, Frank J. Frankovich

Bachelors Theses and Reports, 1928 - 1970

Cretaceous sediments in Montana record events during a period of unusual geologic interest. After a long period of extensive submergence of the area during Jurassic time, came a period of varying continental and marine deposition with consequent variations in the types of sediments laid down. A study of these variations, their extent, and their cause has been the primary object of this thesis.


Isopach Maps And Discussion Of The Ordovician And Devonian Of Montana And Adjacent Areas, Arden F. Blair May 1947

Isopach Maps And Discussion Of The Ordovician And Devonian Of Montana And Adjacent Areas, Arden F. Blair

Bachelors Theses and Reports, 1928 - 1970

The intensive postwar search for new petroleum horizons has resulted in widespread prospecting in the northern Great Plains. No commercial production has as yet been derived from Ordovician or Devonian rocks in Montana, but the relat­ively few tests that have penetrated to critical depths have disclosed encouraging conditions which merit further consider­ation, especially in Devonian strata.


Distribution And Lithology Of Sedimentary Rocks In Montana And Adjacent Areas, Harold Kentta May 1947

Distribution And Lithology Of Sedimentary Rocks In Montana And Adjacent Areas, Harold Kentta

Bachelors Theses and Reports, 1928 - 1970

The general features of the sedimentary rocks in a region, their distribution, and the relationships of these rocks to other rocks of the area and of adjacent areas, are some of the things in which most geologists are interested, for reasons of general curiosity or for obtaining a better understanding of their specific prob­lems


Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis Apr 1943

Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis

Bachelors Theses and Reports, 1928 - 1970

In studying the Cut Bank field and its numerous wells, it is found that dry holes are surrounded by producing wells, and also that the field as a whole is very irregular; water, oil, and gas zones in many cases following no definite pattern. In some instances, this phenomenon may be due to the lensing and thinning of the producing sands, but it is evident that this is not the only factor. There­fore, the controlling factors must be porosity and permeability.


Report Of Investigation On The Physical Characteristics Of The Oil Sands From The Cut Bank Field, Montana, V. E. Hanes Jun 1942

Report Of Investigation On The Physical Characteristics Of The Oil Sands From The Cut Bank Field, Montana, V. E. Hanes

Bachelors Theses and Reports, 1928 - 1970

The purpose of this research was to study the physical characteristics, mainly, porosity and permeability of the oil sands from the Cut Bank field, Glacier County, Montana. In so doing, a better understanding of the relation­ship of these physical characteristics to one another and to the pool itself could be obtained.


Helena And Ennis Talc Deposits, Howard N. Anderson May 1942

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.
