The following report presents a regional study of the extent, thickness, lithology, stratigraphic relations, age, depositional environment, and tectonic history of thick sulfate deposits and associated salts of sodium and potassium.

The following report follows a mineral survey of the Glacier Primitive Area and adjoining area in Wyoming, that was made in 1968 and 1969.

The following report is an evaluation of the mineral potential of the Laramie Peak area, Wyoming.

This report studies the several aspects of the basalts in the Columbia River Basalt Group in the Spokane quadrangle, Washington, Idaho, and Montana.

An index of fossil names between 1820 and 1965. Diatoms, spores, and pollen are excluded from this index.

The following document provides a list of publications about geology which relates to nomenclatural changes.

Abstract: "The Precambrian rocks of Colorado consist of a metaphoric complex more than 1,700 million years in age, three groups of igneous rocks about 1,700, 1,400, and 1,000 million years in age, here designated informal age groups, and two areally restricted units of sedimentary rocks, one between 1,400 and 1,700 million years in age and one between 950 and 1,400 million years. A systematic nomenclature for many of the rocks does not exist, but the present state of knowledge will permit establishment of a comprehensive nomenclature. Numerous formal names that have been applied to elements of the Precambrian assemblage are appraised and classified in a table, and eight names are abandoned."

A report about the United States's coal supply. The U.S. has 25 percent of the world's identified coal resources and about 20 percent of the world's estimated total coal resources.

A bibliography of about 200 selected references which contain information on source materials dealing with the genesis and geochemistry of gold and geochemical prospecting for gold deposits.

A report which compares 20,000 feet of Belt rocks in the Mission Mountains Primitive Area in Montana with 40,000 feet of Belt rocks in the Pend Oreille area in Idaho and Montana.

A paper which provides a list of nomenclatural changes. The list also contains publications, the authors, and the names of the reports.

A report about the lithologic units within a red-bed sequence that help to interpret the history and structure of the Woody Creek quadrangle, west-central Colorado.

A report about clinoptilolite. It is a common zeolite, it is potentially valuable for many industrial and agricultural processes, and it might be useful in controlling water pollution by removing ammonia from wastewater.

A report that provides details about fire assaying techniques to separate and concentrate the noble metals from many varieties of samples.

A report about six cretaceous rock formations in the western Wyoming thrust belt.

A report about mapping in the northern and central parts of the Piceance Creek basin of northwestern Colorado where several relatively thin dominantly marlstone units tongue northward into the Eocene Uinta Formation.

A report about the Coughs Creek Tongue which is a sequence of light-gray marlstone, locally containing beds of sandstone and siltstone, in the upper part of the Green River Formation.

A list of stratigraphic names adopted, revised, reinstated, and abandoned. The nomenclatural changes pertain to geology.

An index of names of new fossil plant genera found in literature between 1966 and 1973 which is now included in the pendium Index of Paleobotany.

A list of stratigraphic names which are adopted, revised, reinstated, or abandoned are listed. The scheme of the list has been devised simply to facilitate depiction and analyses of the Precambrain history of the United States.

A bibliography that lists about 1,300 U.S. Geological Survey publications related to coal and published prior to January 1, 1971.

A bibliography which contains over 500 references for the Albuquerque Greater Urban Area (AGUA). The intent is to be comprehensive in scope in the areas of hydrology and geology as well as introductory in other interdisciplinary areas.

A report about the geology, composition, and stratigraphic nomenclature of the thirtynine mile volcanic field in central Colorado.

A report about the stratigraphic nomenclature changes in geology.
