A crustal deformation observatory near the San Andreas Fault in central California (PB3)
Larry E. Slater
1981, Open-File Report 81-940
This final technical report discusses several objectives and accomplishments of the first years effort of a project titled A Crustal Deformation Observatory Near the San Andreas Fault in Central California. This period saw the conclusion of the Hollister MWDM effort that has produced nearly continuous, high precision, line length measurements...
Ice-gouge data, Beaufort Sea, Alaska, 1972-1980
Douglas M. Rearic, Peter W. Barnes, Erk Reimnitz
1981, Open-File Report 81-950
The interaction of sea ice with the sea floor is an important factor affecting geologic processes on high latitude shelves. One of the most obvious forms of this interaction is the formation of furrow-like gouges or the sea floor. These gouges are caused by wind- and current-driven ice masses that...
Cooperative tectonic studies from seismic network in central Italy
L. Seeber, C.H. Scholz
1981, Open-File Report 81-92
The purpose of the subject contract work was to explore the possibility of tectonic research-work based on seismic data from a local network carried out as a cooperative effort between the Institute Nazionale di Geofisica (ING), Rome, and Columbia University (L-DGO), New York. This effort has been rather successful, and...
Quantitative geomorphology of drainage basins in Sumter National Forest, South Carolina
Glenn G. Patterson
1981, Open-File Report 81-417
This report describes a computer program, written in Basic, that facilitates quantitative analysis of drainage basins and channel networks. The program was used to inventory 2,000 small watersheds in Sumter National Forest, South Carolina during 1980 and 1981. Drainage basins and stream segments were delineated in color on mylar overlays...
Results of exploratory drilling at Point MacKenzie, Alaska, 1981
Leslie Patrick
1981, Open-File Report 81-1072
The Matanuska-Susitna Borough anticipates industrial development near Point MacKenzie, Alaska. Because little hydrologic information is available for the area, the Borough contracted for the drilling of two test wells. It was found that: Both wells penetrated unconsolidated stratified clay, silt, sand, and gravel; each well penetrated a shallow unconfined and...
Mathematical model of gamma-ray spectrometry borehole logging for quantitative analysis
Ulrich Schimschal
1981, Open-File Report 81-402
A technique for analyzing gamma-ray spectral-logging data has been developed, in which a digital computer is used to calculate the effects of gamma-ray attentuation in a borehole environment. The computer model allows for the calculation of the effects of lithology, porosity, density, and the thickness of a horizontal layer of...
Sediment parameters for a fine-grained sediment deposit on the southeastern New England continental shelf
Richard R. Rendigs, Michael H. Bothner, Lawrence J. Poppe
1981, Open-File Report 81-1334
An area of fine-grained sediments south of Martha's Vineyard, Massachusetts, has been interpreted as a contemporary deposit. Textural analysis of cores from this area indicates that the deposit consists of sandy to clayey silts overlying a well sorted relict sand. The maximum thickness of the fine sediments is about 6...
