A Discussion of the Geology and an Isopach Map of the Pennsylvanian System in Wyoming and Adjacent Areas

Pennsylvanian strata in Wyoming and adjacent areas have been the subject of much work and discussion. Most of the work has been due to the economic importance of the system as an oil producer in this region. Oil production from strata of Pennsylvanian age is rather recent history; and therefore, much of the available information is local­ized and incomplete.

Two Approaches to Collaborative Information Literacy Instruction at a Small Engineering School

Two librarians at a small STEM academic library have partnered with professors to develop and teach chemistry and writing courses. These librarians have successfully worked with professors to serve as an active presence within the classroom. This article describes the challenges of navigating the typical obstacles librarians face when attempting to integrate information literacy into the curriculum, reflects on the benefits of these collaborations, and touches on strategies for implementing similar programs at other institutions. It outlines two distinct approaches to collaborating with professors on credit-bearing information literacy courses, along with the key steps involved in planning and implementing these courses, including generating institutional buy-in, identifying potential collaborators, negotiating workload and responsibilities with collaborators, and planning to sustain courses beyond a single academic year. Suggestions for overcoming obstacles, supplemented by experience-based recommendations, are discussed.

The Effect of Manganese and Magnesium on the Hardening of Copper-Aluminum Alloys

During recent years, duralumin and all aluminum alloys have been made the object of much discussion regarding their hardening mechanism. The commercial success of nearly all of the alloys of aluminum and mag­nesium is dependent on their ability to age or precipitation harden.

An Investigation of Age-Hardening in a Commercial Copper-Beryllium Alloy

This investigation is concerned with the age-hardening process as exemplified by the aging of a commercial Cu-Be alloy and, in particular, with this pro­cess as determined by X-ray methods. The amount of infor­mation available on age-hardening of commercial alloys is scanty and what information there is, is inaccurate.

Sandstones of the Lance and Fort Union Formations

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.

The Geology and Mineral Deposits of British Columbia

The province of British Columbia, with an area of 359,279 square miles, includes a large part of the Canadian Cordillera that is the western mountains of Canada. It is the leading province of Canada in the production of lead, zinc, and silver, and third among the provinces in the output of gold, copper, and coal.

Foraminifera from Pleistocene beds near San Pedro, California

The age of rocks found in drill cores, and consequently the depths to possible oil-bearing formations has in many localities been determined by micro-paleontologic studies during the past three decades. Of the different micro-fossils used in this work, foraminifera have been studied most, are the best described, and hence, by far the most helpful.

The Electrodeposition of Iron-Manganese Alloys

Although the alteration of properties resulting from the alloying of metals in their usual commercial forms has been extensively investigated, the field of electrodeposition of alloys is believed generally not to have received the atten­tion that it merits.

An Investigation of the Anodic Oxidation of Aluminum in a Sulfuric Acid Electrolyte

When aluminum is allowed to stand in air or is heated in air, a thin oxide film is produced on the metal. If aluminum is made the anode in a suitable electrolyte and a current applied, a coating is obtained which is similar to that produced in air, but may be effected much quicker. This film is thicker, harder, more resistant to corrosion and abrasion, and more adhesive than the natural oxide. The film is porous and makes an excellent adsorptive for dyes and pigments.

The Continuous Electrodeposition of Manganese

The object of this research was to produce a workable electrolytic cell for the continuous deposition of manganese from aqueous sulphate solutions and determine the critical factors in its oper­ation.

An Isopach Map and a Discussion of the Permian in Wyoming and Adjacent Areas

The accelerated post-war demand for petroleum products with resultant high prices and dwindling reserves has spurred producers to an extensive search for new fields and for ad­ditional production in known fields. Exploration and discov­ery is dependent on the collection and correlation of vast amounts of data both in the field and that found in liter­ature.

A Mineral Dressing Study of the U.S. Grant Ore

This investigation concerns the development of a satis­factory method or extracting or concentrating gold and silver from the ores of the U. S. Grant Mine. The choice between applying an extractive process and one by which the valuable mineral constituents are concentrated depends on more than one factor.

Sulfatizing Roasting of a Copper Sulfide Ore

At present copper sulfide ores are recovered by pyrometallurgical processes. While the recovery of cop­per from sulfide ores by hydrometallurgical means has long been considered attractive, the impurities, low re­covery and mechanical difficulties have kept this process from becoming commercial.
