Zinc and lead deposits of northern Arkansas
Edwin T. McKnight
1935, Bulletin 853
Zinc and lead ores occur in the northern counties of Arkansas, from the Arkansas-Oklahoma line on the west to the Coastal Plain, in Lawrence County, on the east, but are concentrated chiefly in Marion, Boone, Newton, Searcy, Sharp, and Lawrence Counties.  Lead ore was reported in the region as early...
Fifty-sixth annual report of the Director of the Geological Survey
Walter Curran Mendenhall
1935, Annual Report 56
During the fiscal year 1934-35, although directly appropriated funds for the support of the Survey's regular activities have been at a low ebb (see details in later pages), these have been augmented by substantial allocations for closely related work made by the Public Works Administration....
Geology and ground-water resources of the island of Oahu, Hawaii
Harold T. Stearns, Knute N. Vaksvik
1935, Bulletin 1
Oahu, one of the islands of the Hawaiian group, lies in the Mid-Pacific 2,100 miles southwest of San Francisco. The principal city is Honolulu. The Koolau Range makes up the eastern part of the island, and the Waianae Range the western part. Both are extinct basaltic volcanoes deeply dissected by...
Welded rhyolitic tuffs in southeastern Idaho
G. R. Mansfield, C.S. Ross
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...
Pre‐Cambrian and Paleozoic vulcanism of interior Alaska
J.B. Mertie Jr.
1935, Eos, Transactions, American Geophysical Union (16) 292-302
The history of vulcanism in Alaska is a topic of great universal interest, but one which has had no adequate treatment. For some years the writer has been accumulating comparative data on this subject, and it is hoped that this information may some time be sufficiently amplified and coordinated to...
The igneous rocks of the Highwood Mountains of central Montana
Esper S. Larsen Jr., C.S. Hurlbut, C.H. Burgess, D. T. Griggs, Bennett Frank Buie
1935, Eos, Transactions, American Geophysical Union (16) 288-292
The study of the Highwood Mountains was undertaken by a group of men from Harvard University under a grant from the Shaler Memorial Fund of the Department of Geology. The work was under the general direction of Larsen, who, with the assistance of Norman A. Haskell, mapped most of the...
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
Harold T. Stearns
1935, Geological Society of America Bulletin (46) 1467-1482
The Island of Oahu is third in size in the Hawaiian group and lies in the mid-Pacific about 2,100 miles southwest of San Francisco. Honolulu, the capital and principal port of this group, is on Oahu. Two dissected volcanic domes, the Waianae Range (4,035 feet high) and the Koolau Range...
Further tests of permeability with low hydraulic gradients
V.C. Fishel
1935, Eos, Transactions, American Geophysical Union (16) 499-503
Many of the water‐bearing formations in the United States have hydraulic gradients of much less than 20 feet to the mile, and some may have gradients of less than one foot to the mile, whereas most laboratory‐tests of permeability are made with much higher gradients. An investigation was therefore undertaken by the writer, under the direction of 0. E....
