Saline-water resources of North Dakota
Charles Joseph Robinove, R.H. Langford, J.W. Brookhart
1958, Water Supply Paper 1428
Natural waters in North Dakota have been arbitrarily defined in this report as saline or fresh; water containing more than 1,000 ppm (parts per million) of dissolved solids or having a specific conductance greater than 1,400 micromhos per centimeter at 25°C is considered to be saline. A large proportion of...
Phreatophytes
Thomas William Robinson
1958, Water Supply Paper 1423
Phreatophytes are plants that depend for their water supply upon ground water that lies within reach of their roots. Although not confined to the arid regions of the Western United States, their occurrence there is more common, more spectacular, and, because of their effect on water supply, more important than...
Regional gravity survey of the Carrizo Mountains area, Arizona and New Mexico
Donald Plouff
1958, Open-File Report 58-76
A total of 570 gravity stations were established within an area of about 1,000 square miles south of the common corner of Colorado, Utah, Arizona, and New Mexico. The Bouguer gravity anomaly pattern apparently is unrelated to the disposition of minette plugs inasmuch as there probably is little contrast in...
Geology of the Little Commonwealth area, Florence County, Wisconsin
Robert William Johnson Jr.
1958, Open-File Report 58-53
The Little Commonwealth exploration in northeastern Florence County, Wisconsin, is underlain by highly ferruginous clastic rocks that are stratigraphically equivalent to vitreous quartzite. The relationship between these rocks is one of abrupt facies change, with complete gradation between facies. This stratigraphic unit is conformably underlain by sericitic phyllite and unconformably...
The geology and ore deposits of Upper Mayflower Gulch, Summit County, Colorado
John Alexander Randall
1958, Open-File Report 58-79
Upper Mayflower Gulch is on the highly glaciated western side of the Tenmile Range near Kokomo in central Colorado. Somewhat less than $500,000 in silver and gold has been produced from the area since the first mining in the 1880' s. In the mapped area high grade regional metamorphism has...
