Methods of prospecting for mineral deposits by means of chemical studies of residual soil, alluvium, glacial moraine, vegetation, and natural water were first applied on a systematic scale in Scandinavia and Russia about 15 years ago. Since the war, work in this field has been undertaken by several independent groups...

Detailed procedures are presented for the determination of very small percentages of thorium. The methods are designed to determine 0.001% of thorium oxide as the lower limit and are applicable to nearly all types of rocks. For quantities below a milligram of ThO2, the thorium is determined nephelometrically as the...

Les principales rivières de la Plaine du Cul-de-Sac, la Rivière Grise ou Grande Rivière du Cul-de-Sac et la Rivière Blanche, prennent naissance sur le flanc Nord du Massif de la Selle à des altitudes de 1,300 à 1,800 mètres au dessus du niveau de la mer. Elles coulent à l’amont...

The ostracodes described in this report are from material collected in Naval Petroleum Reserve No. 4, northern Alaska. The samples were obtained from well and seismograph shot holes drilled by Arctic Contractors and United States Geophysical Company and from field samples collected by the United States Geological Survey in the...

The late Tertiary volcanism in the San Juan Mountains of southwestern Colorado followed a long interval during which the crust was stable. The volcanic rocks have been divided into four main groups, (1) those of pre‐Potosi (?) age in the eastern area, (2) the Lake Fork quartz latite, San Juan...

A map is presented showing contours of the buried preglacial channel of the Mohawk River from Schenectady, New York, to its confluence with the Hudson River about 12 miles south of Albany and of associated buried preglacial channels. The Pleistocene history of a portion of the Mohawk and Hudson Rivers...

During the 1949 drilling season eight core tests were completed in the Simpson Seeps area up to October 25th„ This program, which is still in progress, was undertaken to provide an explanation for the surface seeps near Caps Simpson. The shallowest of the eight holes reached 800 feet; the deepest...

This paper presents four terrain diagrams, on a scale of 1:1,000,000, which cover all the Philippine Islands. The diagrams were prepared during World War II by the Military Geology Unit of the U. S. Geological Survey for the Chief of Engineers, U. S. Army. Terrain features shown on the diagrams...

Second vertical derivatives of magnetic fields, because of their high resolving power, are often very useful in interpreting magnetic anomalies. Formulas are developed which permit their ready numerical computation. Comparisons are made between the resulting approximate values and the rigorous values obtained for simple idealized fields. The similarity between maps...

The lavas of the Hawaiian Islands range from mafic picrite-basalts and melilite-nepheline basalts to salic trachytes. Olivine basalt, by far the most abundant type, is regarded as representing the parent magma of the Hawaiian province. Closely associated with the olivine basalts are basalts, and picrite-basalts with many large phenocrysts of...
