Geochemical, aeromagnetic, and generalized geologic maps showing distribution and abundance of molybdenum and zinc, Golconda and Iron Point quadrangles, Humboldt County, Nevada
R. L. Erickson, S.P. Marsh
1972, Miscellaneous Field Studies Map 345
Detailed geologic and geochemical studies of the four 7½-minute quadrangles that make up the Edna Mountain 15-minute quadrangle in Humboldt County, Nevada, were begun during the 1969 summer field season. The objectives of the project are to map the geology of this structurally complex area at 1:24,000 scale and to...

Electric analog studies of flow to wells in the Punjab aquifer of West Pakistan
Maurice John Mundorff, G.D. Bennett, Masood Ahmad
1972, Water Supply Paper 1608-N
A series of experiments was performed with a steady-state electric analog simulating a cylindrical segment of the aquifer underlying the plains of the Punjab region of West Pakistan. In most of the experiments recharge was assumed to be from the surface, within a specified radius of influence, and distributed uniformly...
Water quality of streams in the Neshaminy Creek basin, Pennsylvania
Edward F. McCarren
1972, Water Supply Paper 1999-O
The Neshaminy has carved a scenic route on its way to the Delaware River, thereby helping to increase the value of land. The unabated growth of nearby metropolitan areas and the multiplying needs for water and open space for water storage and recreation in southeastern Pennsylvania have become impelling forces...
