Drainage divides, Massachusetts; Housatonic River basin
Russell A. Gadoury, S. William Wandle Jr.
1983, Open-File Report 82-634
Drainage boundaries for selected subbasins in Berkshire County, Massachusetts, are delineated on 12 topographic quadrangle maps at a scale of 1:24,000. Drainage basins are shown for all U.S. Geological Survey data-collection sites and for mouths of major rivers. Drainage basins are shown for the outlets of lakes or ponds and...
Lineaments and fracture traces, Decatur County, Indiana
Theodore K. Greeman
1983, Open-File Report 82-918
Lineanents and fracture traces have been mapped throughout Decatur County, Indiana. These lineaments and fracture traces may indicate that solution enlarged vertical fractures in the limestone and dolonite aquifers underlie most of the county. The use of lineament and fracture-trace maps in selecting bedrock-drilling sites results in a significant increase...
Linear features determined from Landsat imagery in North Dakota
M. E. Cooley
1983, Open-File Report 83-937
The report consists of a map (scale 1:500,000) that shows the linear features determined from Landsat imagery in North Dakota. The linear features, sometimes called linear trends or lineaments, are not identified as to type or origin. Most probably represent fractures or fracture zones, which may affect the movement of...
A surface vitrinite reflectance anomaly related to Bell Creek oil field, Montana, U.S.A.
C.E. Barker, M.C. Dalziel, M. J. Pawlewicz
1983, Open-File Report 83-826
Vitrinite reflectance measurements from surface samples of mudrock and coal show anomalously high values over the Bell Creek oil field. The average vitrinite reflectance (Rm) increases to a maximum of 0.9 percent over the field against background values of about 0.3 percent. The Rm anomaly coincides with a geochemical anomaly...
PHRQINPT, an interactive computer program for constructing input data sets to the geochemical simulation program PHREEQE
G.W. Fleming, Niel Plummer
1983, Water-Resources Investigations Report 83-4236
PHRQINPT is a FORTRAN 77 program which facilitates formulation of the input data file to PHREEQE (Parkhurst, Thorstenson, and Plummer, 1980). PHRQINPT runs interactively and contains many features to help the user construct the input data set. This report describes these features and gives instructions on the use and implementation...
The environmental history and present condition of Saudi Arabia's northern sand seas
John W. Whitney, D.J. Faulkender, Meyer Rubin
1983, Open-File Report 83-749
Saudi Arabia's northern sand seas are composed dominantly of stable dune systems, even though the modern climate is arid. The stable dunes are large and support a sparse semidesert vegetation. Active dunes are small and commonly confined to the crests of stable dunes; they comprise less than 5 percent of...
Basic program "IPFLTR" for induced polarization data reduction and filtering
Hamdy S. Sadek
1983, Open-File Report 83-485
The recently developed induced polarization (IP) mapping technique can be successfully applied to IP dipole-dipole data and includes three types of filters that can be applied to IP pseudosections that have IP anomalies caused by different types of sources. The technique yields a single output value per station; this value...
Water resources of Hanson and Davison Counties, South Dakota
D. S. Hansen
1983, Water-Resources Investigations Report 83-4108
Five glacial and four bedrock aquifers were delineated in Hanson and Davison Counties. The glacial aquifers, outwash deposits confined by as much as 275 feet of glacial till, are the Floyd, Plum Creek, Ethan, Warren, and Alexandria. The bedrock aquifers are the Niobrara, Codell, Dakota, and Sioux Quartzite Wash, and...
