A rapid, sensitive, and specific field method useful in geochemical exploration has been developed for the determination of silver in geologic materials. In this method the sample is digested with nitric acid and the silver is extracted with triisooctyl thiophosphate (TOTP) in benzene and stripped from the organic phase with...

This remote 700 square mile area in the Brooks Range is topographically rugged and geologically diverse; it contains a granitic pluton, low-grade metamorphic rocks, sedimentary rocks, and mafic igneous rocks, as well as glacial features.Rocks of sedimentary origin include from oldest to youngest:1.Neruokpuk Formation Middle and Upper Devonian(?), more than...

In the central York Mountains, carbonate rocks of Lower and Middle Ordovician age and aggregating at least 8,000 feet thick are thrust northward over slate and argillaceous limestone of pre-Ordovician age which were intruded by gabbro in pre-Ordovician time. Normal faults of four distinct systems cut the thrust plates, and...

During the summers of 1963 and 1964, a regional gravity survey covering 6,000 square miles of the San Luis Valley and surrounding areas was made to determine subsurface basement configurations and to guide future crustal studies. The San Luis Valley, a large intermontane basin, is a segment of the Rio...

Sedimentary iron and heavy-metal deposits of undetermined size have been found in the middle of the Red Sea some 2000 meters below the surface of the sea. This discovery has been made from the Research Vessel Atlantis II, which is still at sea engaged in a series of oceanographic investigations which...

The U. S. Geological Survey began, in November 1963, a terrain analysis of the lunar equatorial belt (10°N-10°S, 60° W15°E), on behalf of the National Aeronautics and Space Administration. The purpose of the study is to establish a quantitative classification system in terms of different degrees of relative resolvable roughness,...

The falling-drop method of density determination has been modified so that the densities of a standard and a sample water are compared simultaneously. A constant temperature bath that does not vary more than 0.0001°C and an accurate double micropipet are described. The method has sufficient sensitivity and precision to distinguish...

About 20 miles north of Butte and extending nearly to Helena, is an area of 350 square miles containing hundreds of veins and altered zones. The bedrock of the area is 1) late Cretaceous volcanic rocks, forerunners of the Boulder batholith, 2) the Boulder batholith of late Cretaceous to early...
