Mineral resource potential of the Stillwater Complex and adjacent rocks in the northern part of the Mount Wood and Mount Douglas quadrangles, southwestern Montana
Norman J. Page, John C. Dohrenwend
1973, Circular 684
The Stillwater Complex contains the largest potential chromite and platinum metal resources and second largest nickel resources in the United States. The Ultramafic zone has produced about 900,000 long tons of chromite concentrate and contains unmined reserves equivalent to 2,520,000 long tons of Cr2O3. Nickel and copper sulfide minerals that...
Water resources data for Maine, water year 1972
Water Resources Division, U.S. Geological Survey
1973, Water Data Report ME-72-1
Water resources data for the 1972 water year for Maine including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, records of water-quality data on the chemical and physical characteristics of surface- and ground-water, and records of ground-water levels in index wells are given in...
A network for continuous monitoring of water quality in the Sabine River basin, Texas and Louisiana
J.F. Blakey, P.W. Skinner
1973, Open-File Report 73-25
The proposed water-quality network for the Sabine River Basin of Texas and Louisiana consists of nine monitoring stations, a central control station, a slave-central station, and a leased-line telecommunications system. This monitoring network would provide continuous transmission of water-quality data to the office of the water manager. Level I operations at...
Relation of channel slope to reaeration of Michigan streams
T. Ray Cummings
1973, Open-File Report 73-54
Reaeration coefficients (k2), which are rate constants for the process of oxygen absorption from the atmosphere, have been computed for Michigan's streams using an equation developed by Bennett and Rathbun (1972). Mean velocity and mean depth data, which are necessary for the computation, have been extracted from discharge measurements made...
Preliminary report on the geology along the Atlantic Continental margin of the northeastern United States
James P. Minard, W. J. Perry Jr., Elaine G. A. Weed, E. C. Rhodehamel, E. I. Robbins, R. B. Mixon
1973, Open-File Report 73-191
The U.S. Geological Survey is conducting a geological and geophysical study of the northeastern United States Outer Continental Shelf and the adjacent slope from Georges Bank to Cape Hatteras. The study also includes the adjacent Coastal Plain because it is a more accessible extension of the shelf. The total study...
Summary of seismic activity and its relation to geology and mining in the Sunnyside mining district, Carbon and Emery Counties, Utah, during 1967-1970
C. Richard Dunrud, Frank W. Osterwald, Jerome Hernandez
1973, Open-File Report 73-63
In the Sunnyside mining district, Utah, coal is mined under thick and variable overburden which is locally weakened by faults and other structural discontinuities. Stress changes and local stress concentrations produced by mining under these conditions often cause sudden and violent ruptures in the coal and surrounding rock mass. The...
