Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples

From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."

Geology of the High Climb Pegmatite, Custer County, South Dakota

From abstract: The High Climb pegmatite, Custer County. S. Dak., belongs to the series of pegmatitic and granitic rocks that characterize the Harney Peak region of the southern Black Hills. It intrudes pre-CamInbriani metamorphic rocks consisting chiefly of quartz-mica schist. Along part of the pegmatite contact the country rock has been altered to a tourmaline-rich schist.

The Moraines of the Missouri Coteau, and their Attendant Deposits (open access)

The Moraines of the Missouri Coteau, and their Attendant Deposits

Introduction: It seems important that several general facts should be stated for the full understanding of terms used and allusions made in this report. The field considered is the region lying between the Missouri and James rivers, and between the latitudes of Jamestown, N. Dak., and Huron, S. Dak. 1. As has been stated in papers published by Chamberlin, Upham, myself, and others, several more or less distinct moraines have been observed in the Mississippi Valley. It has been found convenient to distinguish the outermost three by special names. President Chamberlin has named them, beginning with the outermost, Altamont, Gary, and Antelope moraines, from localities south of Big Stone Lake, and these names have been quite generally adopted. Upham and others have named them the First, Second, and Third, and as the outermost two are the more prominent, they have also been called the Outer and Inner moraines. Each of these, especially the First and Second, has subordinate divisions, which mark the borders of the different lobes into which the margin of the ice sheet was often divided. 2.) It is assumed that the reader is familiar with the generally recognized features of drift formations, such as the undulating topography …

National Uranium Resource Evaluation: Newcastle Quadrangle, Wyoming and South Dakota

Uranium resources of the Newcastle 1°x2° Quadrangle, Wyoming and South Dakota were evaluated to a depth of 1,500 m (5000 ft) using available surface and subsurface geologic information. Many of the uranium occurrences reported in the literature and in reports of the U.S. Atomic Energy Commission were located, sampled and described. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, were outlined. Areas favorable for uranium deposits in the subsurface were evaluated using gamma-ray logs. Based on surface and subsurface data, two areas have been delineated which are underlain by rocks deemed favorable as hosts for uranium deposits. One of these is underlain by rocks that contain fluvial arkosic facies in the Wasatch and Fort Union Formations of Tertiary age; the other is underlain by rocks containing fluvial quartzose sandstone facies of the Inyan Kara Group of Early Cretaceous age. Unfavorable environments characterize all rock units of Tertiary age above the Wasatch Formation, all rock units of Cretaceous age above the Inyan Kara Group, and most rock units of Mesozoic and Paleozoic age below the Inyan Kara Group. Unfavorable environments characterize all rock units of Cretaceous age above the Inyan Kara Group, and all rock units of Mesozoic and …

Grain Farming in the Corn Belt with Live Stock as a Side Line

"This bulletin is written to suggest to the corn-belt farmer of the Middle West -- especially the farmer whose soil has been run down by continuous grain farming -- some ways of coordinating and 'cashing in' the scientific advice offered him in hundreds of bulletins already published.... Briefly, these are the conclusions reached by our most successful corn-belt farmer and agricultural experts: To make a money-maker of a farm that has become a losing proposition through steady grain farming you must in addition to raising standard grain crops -- (1) Grow legumes, (2) Raise live stock as a side line, (3) Keep accounts of receipts and expenditures, (4) Mix horse sense with scientific agriculture, (5) Try to secure enough capital to enable you to farm right, (6) Stick to whatever policy you adopt long enough to try it out, and (7) Confer with your County Agent and make a careful study of the bulletins of the United States Department of Agriculture." -- p. 1-3.
