Means of recognizing source beds
P.D. Trask, H.W. Patnode
1936, Conference Paper
Eight characteristics of sediments are considered as possible means of recognizing source beds: 1, quantity of organic matter in the sediments; 2, reducing power, which is a measure of ability of the sediments to reduce chromic acid; 3, color of sediments; 4, volatility of sediments; 5, degree of volatility, which...

1935, Eos, Transactions, American Geophysical Union (16) 308-321
Rocks of rhyolitic type in eastern Idaho and adjacent parts of Wyoming were observed by the Teton Division of the Hayden Surveys under Orestes St. John (Report of the geological field work of the Teton Division, U.S. Geol. and Geog. Surv. Terr., 11th Ann. Rep., pp. 498–504, 1879), who described...
The pre-Cambrian igneous rocks of eastern Pennsylvania and Maryland
Florence Bascom
1935, Transactions, American Geophysical Union (16) 328-350
The Blue Ridge and Piedmont geomorphic provinces, topographically distinct but geologically a unit, extend southwestward across eastern Pennsylvania and central Maryland, in a belt with an average width in these States of some 50 miles. In these provinces are exposed the crystalline formations of the Atlantic belt. Gneisses (with sporadic...
Shore benches on the island of Oahu, Hawaii

Further remarks on the Cripple Creek Volcano, Colorado
G. F. Loughlin
1933, Eos, Transactions, American Geophysical Union (14) 243-243
Structural evidence, particularly in the deeper mine‐workings, indicates that the volcano, which is of Tertiary age, was developed by explosive eruptions at a number of points along intersecting fissure‐systems that had been formed in pre‐Cambrian granite by east‐west compression, probably during the Laramide revolution. The volcanic breccia, which consists principally of...
Fluctuations of water‐surface in observation‐wells and at stream gaging‐stations in the Mokelumne Area, California, during the earthquake of December 20, 1932
Arthur M. Piper
1933, Eos, Transactions, American Geophysical Union (14) 471-475
On December 20, 1932, much of the western United States felt a pronounced earthquake‐shock which caused noticeable fluctuations of the water‐surface in several observation‐wells and at two stream gaging‐stations in the Mokelumne Area, central California. These effects of the earthquake are reported briefly in this paper.According to Dr. Byerly (personal...
