Geochemical prospecting for copper and nickel in the Wulgai and Tor Tangi areas southeast of Hindubagh, Quetta Division, Pakistan
S. Anthony Stanin, M.A. Wahid, Shamsher Khan
1975, Open-File Report 75-163
Showings of magnetite, copper, and possible nickel mineralization in the Hindubagh chromite mining district are near Wulgai and Tor Tangi. Several hundred samples of clastic material from dry streambeds in these areas were sieved for the minus-80-mesh fraction and analyzed for copper using 2, 2'-biquinoline and for nickel using alpha-furildioxime....
Hydrology for land-use planning: The Hillside area, Anchorage, Alaska
Larry L. Dearborn, William W. Barnwell
1975, Open-File Report 75-105
Rapid residential growth of the Hillside area, Anchorage, Alaska, may cause depletion of aquifers and a change in quality of water resources as a result of extensive development of small-lot tracts. Ground-water yields are low and may be locally inadequate for single family requirements where wells produce from bedrock in...

Titanium minerals in deposits of other minerals
Eric R. Force
1975, Open-File Report 75-34
Titanium minerals in amounts equivalent to a significant portion of present world production are moved but not recovered from mines of other commodities. Resources of this type total in the millions of tons of contained TiO2. Among the possible sources for byproduct titanium are (1) ilnenite and minor rutile detrital...
Heavy mineral prospecting in Pakistan
Karl W. Stauffer, James Alfred Calkins
1975, Open-File Report 75-359
Heavy-mineral prospecting is a method of tracing potential ore minerals to their source by systematically examining the heavy minerals of stream sands. The heavy minerals are partially concentrated in the field by panning. In the laboratory the heavy minerals are further concentrated by floating off the quartz and feldspar in...
