Zirconium and hafnium in the southeastern Atlantic States
J.B. Mertie Jr.
1958, Bulletin 1082-A
The principal source of zirconium and hafnium is zircon, though a minor source is baddeleyite, mined only in Brazil. Zircon is an accessory mineral in igneous, metamorphic, and sedimentary rocks, but rarely occurs in hardrock in minable quantities. The principal sources of zircon are therefore alluvial deposits, which are mined...
Bedrock geology of the southwestern part of the North Range, Cuyuna district, Minnesota
R. G. Schmidt
1958, Miscellaneous Field Studies Map 181
The Cuyuna manganiferous iron-ore district is in central Minnesota in Morrison, Crow Wing, and Aitkin Counties.  The length of the district is about 68 miles, extending northeastward from a point near Randall, in Morrison County, to a point 11 miles east of the community of Hassmann in Aitkin County; the...
Ground water in the alluvial deposits of the Washita River and its tributaries in Oklahoma
A.R. Leonard, L.V. Davis, B.L. Stacy
1958, Open-File Report 58-63
Physical features.--The Washita River heads in the Texas Panhandle, in Hemphill, Roberts, and Wheeler Counties. It flows generally east-southeastward through southwestern and south-central Oklahoma to its confluence with the Red River above Denison, Texas, at a point about 4 miles northwest of Cartwright, Oklahoma. That point of confluence is now...
History of natural flows--Kansas River
Elwood R. Leeson
1958, Open-File Report 58-62
Through its Water Resources Division, the United States Geological Survey has become the major water-resources historian for the nation. The Geological Survey's collection of streamflow records in Kansas began on a very small scale in 1895 in response to some early irrigation interest, Since that time the program has grown,...
Metamorphosed middle Paleozoic fossils from Central Massachusetts, eastern Vermont, and western New Hampshire
A. J. Boucot, G.J.F. Macdonald, C. Milton, James B. Thompson Jr.
1958, Geological Society of America Bulletin (69) 855-870
Study of thin and polished sections and spectrographic analyses indicate that the brachiopod most recently used to date the Bernardston Formation in Massachusetts probably came from Lower Devonian beds (chlorite zone) in Nova Scotia, and not from Bernardston, Massachusetts. Restudy of the faunule from the calcareous quartzite (garnet zone) of...
Stratigraphy of ocoee series, Great Smoky Mountains, Tennessee and North Carolina
P.B. King, J. B. Hadley, R. B. Neuman, W. Hamilton
1958, Geological Society of America Bulletin (69) 947-966
Much of the Great Smoky Mountains, which span the boundary between Tennessee and North Carolina, is formed of the Ocoee series, of later Precambrian age. This is a body of terrigenous clastic sedimentary rocks, which has minor intercalations of limestone and dolomite but no volcanic components or known fossils. The...
Geology of Kapingamarangi Atoll, Caroline Islands
Edwin D. McKee
1958, GSA Bulletin (69) 241-278
Kapingamarangi Atoll of the Caroline Islands consists of a peripheral reef, 1000-4000 feet across, surrounding a nearly circular lagoon which is 5 by 6 nautical miles in area and about 240 feet at maximum depth. Thirty-three islands, most of which are less than half a mile in length, are scattered...
Uranium deposits under conglomeratic sandstone of the Morrison Formation, Colorado and Utah
D. A. Phoenix
1958, GSA Bulletin (69) 403-418
In southwestern Colorado and southeastern Utah, strata of conglomeratic sandstone are localized at the base of the Brushy Basin Member of the Morrison Formation of Jurassic age. These discrete lithologic units contain sedimentary structures oriented in a prevailing easterly direction. They are believed to cover about one-third of the underlying...
Eastern glossy ibis nesting in southeastern Maryland
R. E. Stewart
1957, The Auk (74) 509-509
On June 25, 1956, Don P. Fankhauser and I investigated a large heron colony of mixed species, on Mills Island in Chincoteague Bay, Worcester County, Maryland. Large numbers of American Egrets (Casmerodius albus), Snowy Egrets (Leucophoyx thula), Louisiana Herons (Hydranassa tricolor), Little Blue Herons (Florida caerulea), and Black-crowned Night Herons...
Geology of the Basin Quadrangle, Montana
Edward Thompson Ruppel
1957, Open-File Report 58-87
The Basin quadrangle, in the northern part of the Boulder Mountains between Butte and Helena, Montana, is underlain principally by igneous rocks that include Late Cretaceous quartz latitic and andesitic Elkhorn Mountains volcanics, quartz monzonite and related rocks of the Boulder batholith, Oligocene(?) quartz latitic volcanic rocks, and late Miocene(?)-early...
Glacial features and surficial deposits of the Malaspina district, Alaska
George Plafker, Don John Miller
1957, Open-File Report 57-91
The Malaspina district extends about 50 miles along the north shore of the Gulf of Alaska from Icy Bay and the Guyot Glacier on the west to Yakutat Bay and Disenchantment Bay on the east (see index map). The district includes a coastal lowland flanked on the north by a...
Preliminary geologic map of the Pumpkin Buttes area, Campbell and Johnson Counties, Wyoming, showing location of uranium occurrences
W. N. Sharp, A. M. White
1957, Miscellaneous Field Studies Map 98
The Pumpkin Buttes area comprises about 450 square miles in Campbell and Johnson Counties that includes several prominent buttes known as Pumpkin Buttes.  The area is near the center of the Powder River Basin, a large physiographic unit of prairie and sculptured terrain that occupies approximately 12, 000 square miles...
Geology of the southern Elkhorn Mountains, Jefferson and Broadwater Counties, Montana
M. R. Klepper, R. A. Weeks, E. T. Ruppel
1957, Professional Paper 292
The geology of an area of about 270 square miles in the southern Elkhorn Mountains, west of Townsend in west-central Montana, is described. The mountains in the southern part of the area comprise northward-trending alternating ridges and valleys underlain principally by folded sedimentary rocks. They merge northward into the higher...
Water resources of the Yadkin-Pee Dee River basin, North Carolina
Robert Eugene Fish, H. E. LeGrand, G. A. Billingsley
1957, Water Supply Paper 1415
Sufficient water is available in the basin of the Yadkin and Pee Dee Rivers to meet present requirements and those for many years to come if water use increases at about the present rate. Data presented in this report show that the average annual streamflow from approximately 82 percent of...
