An area of 10,000 sq. km between Bi'r Idimah and Wadi Haraman in southern Saudi Arabia was investigated for mineral deposits during the period May 8, 1965, to June 27, 1965. At least 25 different minerals and industrial rocks occur in the area, but of these materials only asbestos seems...

The meteorite classes of Prior and Mason are assigned to three proposed genetic groups on the basis of a combination of compositional, mineralogical, and elemental characteristics: l) the calcium-poor, volatile-rich carbonaceous chondrites and achondrites; 2) the calcium-poor, volatile-poor chondrites (enstatite, bronzite, hypersthene, and pigeonite), achondrites (enstatite, hypersthene, and pigeonite), stonyirons...

More than 50 ash-fall tuff beds which have altered to analcitized or feldspathized rocks have been found in the upper 500-600 feet of the Parachute Creek Member of the Green River Formation in the Piceance Creek Basin of northwestern Colorado. Similarly altered water-washed tuff occurs as tongues in the uppermost...

The geologic setting of the pyrite replacement deposit at Wadi Wassat was mapped in February 1966. From this mapping it is inferred that the pyrite deposits occur along a sub-vertical, north-trending fault in andesite and other rocks at the crest line of an anticline in a roof pendant. The pendant...

This report presents a preliminary Lunar Exploration Plan (LEP) for the Marius Hills region of the Moon. The Marius Hills region is one of the six sites considered by the GLEP site selection group as a candidate for manned exploration using mobility systems allowing a radius of operation of at...

Infrared imagery, in the 3-5 micron band, was obtained during afternoon and post-sunset hours of August 1966 by the H.R.B. Singer Corporation on contract to the U. S. Geological Survey. Analysis of these data reveals that known thermal features such as hot and cold springs, glaciers and snow fields and...

Water-discharge, velocity, and slope variations for a 3.7-mile-Iong tidal reach of the Willamette River at Portland, Oreg., were defined from discharge measurements and river stage data collected between July 1962 and January 1965. Observed water discharge during tide-affected flows, during floods, and during backwater from the Columbia River and recorded...
