Gold distribution in surface sediments on the continental shelf off southern Oregon: A preliminary report
H. Edward Clifton
1968, Circular 587
Local concentrations of gold have been identified in surface sediments on the continental shelf off southern Oregon between Cape Arago and Cape Sebastian, a distance of about 40 miles. Concentrations of gold range from the lower limit of detection, 5 parts per billion, to almost 150 parts per billion. The largest...

1968, Water Supply Paper 1757-J
For much of Kordofan Province, surface-water supplies collected and stored in hafirs, fulas, and tebeldi trees are almost completely appropriated for present needs, and water from wells must serve as the base for future economic and cultural development. This report describes the results of a reconnaissance hydrogeologic investigation of the...

Generalized hydrology of prairie potholes on the Coteau du Missouri, North Dakota
William Stewart Eisenlohr, Charles E. Sloan
1968, Circular 558
This report presents all the information, obtained during the investigation, that lends itself to generalization. It describes conditions on that part of the Coteau du Missouri where there is little integration of drainage systems. The surface of the glacial drift in this region is dotted with shallow depressions known as...

Reconnaissance investigations of the discharge and water quality of the Amazon River
Roy Edwin Oltman
1968, Circular 552
Selected published estimates of the discharge of Amazon River in the vicinity of Obidos and the mouth are presented to show the great variance of available information. The most reasonable estimates prepared by those who measured some parameters of the flow were studied by Maurice Parde, who concluded that the...

A mineral reconnaissance of the Jabal Khida quadrangle, Saudi Arabia
Jesse William Whitlow
1968, Open-File Report 68-325
Reconnaissance of the Jabal Khida quadrangle shows that granite and granodiorite (unit gg), biotite and hornblende granite (unit gr) and alkalic and paralkalic granit (unit gp) divisions for granites seems valid, but that two ages of metamorphic and extrusive rocks are mapped as the Halaben formation (unit ha/hc). Semiquantitative analyses of...
