R. V. Allen, W. E. Davis
1969, Open-File Report 69-6
Introduction Geophysical studies were continued in the Bi'r Idimah-Wadi Wassat area during February 1965. Detailed electromagnetic measurements were made along selected traverses over the northern part of the gossan to supplement earlier dip-angle data; and reconnaissance surveys were made over the central and southern parts of the gossan. Gossan is exposed...

Platinum, palladium, and rhodium analyses of ultramafic and mafic rocks from the Stillwater Complex, Montana
Norman J. Page, Leonard Benjamin Riley, Joseph Haffty
1969, Circular 624
Analyses by a combination fire- assay-solution-optical-emission spectrographic method of 137 rocks from the Stillwater Complex, Mont., indicate that platinum, palladium, and rhodium are preferentially concentrated in chromitite zones. The A chromitite zone (21 samples) has an average of 988.9 ppb (pans per billion, 10-9) Pt, 2290.2 ppb Pd, and 245.9...

1969, Circular 529-B
The movement of a solute, as represented by a soluble fluorescent dye, was observed in the Potomac River estuary at Washington, D.C. The average net rate of downstream movement of the solute centroid was less than 0.6 mile per day. The movement of a solute is highly dependent on the...
