The Dry Lake Section Of The Brazer Foundation, James S. Yolton May 1943

The Dry Lake Section Of The Brazer Foundation, James S. Yolton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Dry Lake section of the Brazer formation, totalling 3100 feet in thickness, is an excellent exposure containing an abundance of fossils many of which are well preserved. The fauna indicates that the formation is to be correlated with the Upper Iowan and Chester series of the type Mississippian system in the Mississippi Valley section. Substantial fossil evidence indicates the following correlation for the Brazer formation members. The C unit represents the western equivalent of the Middle Meramec group, i.e., the Salem and St. Louis limestones. The D member is decidedly Ste. Genevieve in general faunal aspects but, because of …


Phosphate Deposits In Western Summit, Wasatch, Salt Lake, Morgan, And Weber Counties, Utah, Alvin M. Hanson May 1942

Phosphate Deposits In Western Summit, Wasatch, Salt Lake, Morgan, And Weber Counties, Utah, Alvin M. Hanson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphate deposits in the western United States have been the subject of considerable discussion in the last decade, and during the last few years much interest has been aroused in them. Phosphate was first discovered in this area in 1889, but it was not until 1906 that the United States Government took active interest in the study of these deposits. The investigation by the government of the occurrence of western phosphate was begun by Weeks and Ferrier (10), and later carried on by others. On December 9, 1908 the western phosphate reserve was created and many acres of land were …


Cambrian Stratigraphy In The Northern Wasatch Region, George Burke Maxey May 1941

Cambrian Stratigraphy In The Northern Wasatch Region, George Burke Maxey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An exhaustive field study of the Cambrian stratigraphy of the northern Wasatch region indicates that in addition to the Blacksmith Fork section there are two complete and better exposed middle and upper sections. Several other good exposures of the lower Middle Cambrian section have been studied in detail. The Spence shale is found to be a member low in the Langston, not the basal member of the Ute. Relative ages of the Spence shale and Ptarmigania faunas have been determined. Other Cambrian faunal zones have been discovered and are discussed. Paleontologic evidence suggests that the Nounan formation is of Upper …


Glaciation In The Logan Quadrangle, Utah, J. Llewellyn Young May 1939

Glaciation In The Logan Quadrangle, Utah, J. Llewellyn Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That the higher valleys of the Wasatch Mountains were occupied by Pleistocene glaciers has long been known. King, Hague, and Emmons, geologists of the Fortieth Parallel Survey, the first to undertake a systematic study of any part of the Wasatch Mountains, recognized this fact and their report includes a map which shows in a rough way the extent of the glaciated areas in the Central Wasatch (11 ). In 1909 Atwood (1) made a detailed study of the glacial features of the Central Wasatch in connection with his study of glaciation in the Uinta Mountains. He mapped the deposits of …


The Geology Of A Part Of The Bear River Range And Some Relationships That It Bears With The Rest Of The Range, Vic E. Peterson May 1936

The Geology Of A Part Of The Bear River Range And Some Relationships That It Bears With The Rest Of The Range, Vic E. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The structure of the western three or four miles of the Bear River range east of Logan, Utah, has many times been alluded to in papers written locally on Cache Valley and the related ranges. There has not however, ever been, to the author's knowledge, an investigation made of this portion of the range for the express purpose of determining its exact structure. Although the area specifically covered by this present investigation is greatly inadequate to base the whole west range structure on, the author believes that the facts brought to light by the specific study of this area, added …


The Devonian Of The Bear River Range, Utah, I. Lavell Cooley May 1928

The Devonian Of The Bear River Range, Utah, I. Lavell Cooley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The geological column in northern Utah has had very little detailed study. Those who have made reports on this section have done so only in a very general way, making no detailed sections of any part of the column, excepting that of the Cambrian made by Walcott.1 Other work has been done by Mansfield2 in southeastern Idaho and a general section of the Devonian made in Green Canyon, Bear River Range, Utah by Kindle.3

Due to the lack of any detailed work of this nature being done in the Bear River Range, suggested the matter of making …
