A Preliminary Study Of The Ostracoda Of The Big Snowy Group, Mississippian, Of Montana., John C. Rabbitt

Bachelors Theses and Reports, 1928 - 1970

In the field, samples were taken vertically and horizon­tally along the various outcrops in different sections of central and south-central Montana. At important localities the samples were taken about every half-foot verti­cally; in other sections they were taken every few feet.

Geology And Acid Intrusions Of Marlboro Township, Vermont, Stanley Gordon Elder

Honors Papers

It is the aim of this paper to examine the mineralization resulting from the intrusion of acid dikes and veins into the schists of Marlboro township, Vermont, and to give a brief account of the geology of the area.

The problem of mineralization in southern Vermont is one which has been treated very slightly and is one which is deserving of more study than it has received. This problem results from the presence of numerous acid igneous masses in all the formation of the region. Petrographic research in the igneous intrusions was done partially with the hope that the study …

Age Relationships Of Ore Deposits Of Southwestern Montana (A Microscopic Study), Charles R. Trueworthy

Bachelors Theses and Reports, 1928 - 1970

Although considerable work has been undertaken by some prominent geologists, the best known of which is that of Paul Billingsley and J. A. Grimes', in investigating the ore deposits of the Boulder Batholith and surrounding area, there has not been any complete microscopic investigation of these deposits, as a whole, published in the literature. With this in mind it was suggested to the writer by Professor Paul A. Schafer, of the Montana School of Mines, that a microscopic study of the ores of this region would be a worthwhile geologic problem.

It was thought that the mineral association and the …

The Neocene Lake Beds Of Western Montana And Descriptions Of Some New Vertebrates From The Loup Fork, Earl Douglass

Graduate Student Theses, Dissertations, & Professional Papers

Since coming to Montana in the spring of 1894 I have spent rnuoh of ay time in studying the lake bed deposits in the western part of the state, and in collecting and studying the vertebrate fossils found in them. These deposits occur in nearly every large valley in the westem part of the state. I have myself observed them in the valleys of the upper Missouri (above the re-rrion of Helena), Gallatin, Madison, Jefferson, Beaverhead, Ruby, Big Hole, Hell Gate, and Bitter Boot rivers, and their tributaries.
