Precambrian Well Data In Nebraska, Including Rock Type And Surface Configuration, Marvin P. Carlson Feb 1967

Precambrian Well Data In Nebraska, Including Rock Type And Surface Configuration, Marvin P. Carlson

Conservation and Survey Division: Faculty and Staff Publications

This bulletin presents, in tabular form, information relating to the Precambrian surface and includes a configuration map of this surface in Nebraska. The data from all of the 1460 deep tests reaching the Precambrian as of January 1, 1966 are listed. It is anticipated that further studies utilizing this data will be made due to the important influence of the Precambrian surface on later sedimentation and structure and the possibility of minerals of economic importance being present in Precambrian rocks. Specific information for each well and samples, except as noted in the tabulation, are on file and available for study …

Roughness Characteristics Of Natural Channels, Harry H. Barnes Jr. Jan 1967

Roughness Characteristics Of Natural Channels, Harry H. Barnes Jr.

United States Geological Survey: Publications

Color photographs and descriptive data are presented for 50 stream channels for which roughness coefficients have been determined. All hydraulic computations involving flow in open channels require an evaluation of the roughness characteristics of the channel. In the absence of a satisfactory quantitative procedure this evaluation remains chiefly an art. The ability to evaluate roughness coefficients must be developed through experience. One means of gaining this experience is by examining and becoming acquainted with the appearance of some typical channels whose roughness coefficients are known. The photographs and data contained in this report represent a wide range of channel conditions. …

Geology And Structure Of A Portion Of The Rio Puerco Fault Belt, Western Bernalillo County, New Mexico, Jock Campbell Nov 1966

Geology And Structure Of A Portion Of The Rio Puerco Fault Belt, Western Bernalillo County, New Mexico, Jock Campbell

Earth and Planetary Sciences ETDs

The Rio Puerco fault belt is a transitional feature between the Colorado Plateau and the Rio Grande depression in west-central New Mexico.

The major purpose of this report has been to map in detail a portion of the Rio Puerco fault belt not previously investigated thoroughly. The main interest herein is the structure of the area. Particular attention has been given to the determination of the character of the Apache graben. Secondary emphasis is placed on stratigraphy, as more complete reports concerning the sedimentary section can be found elsewhere.

Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen Jan 1965

Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen

Conservation and Survey Division: Faculty and Staff Publications

The first major contribution of the Conservation and Survey Division to Pleistocene stratigraphy was that of A. L. Lugn (1935) who established a classification of the periglacial deposits of the state and related these deposits to the glacial stages. G. E. Condra and E. C. Reed (1950) used information aquired during the 1935-1950 period in making important revisions to Lugn's classifications. This report was a further revision based on studies made from 1950 to publication date (1965).
