Glaciation of the east slope of Rocky Mountain National Park, Colorado
Gerald M Richmond
1960, Bulletin of the Geological Society of America (71) 1371-1382
The eastern slope of Rocky Mountain National Park, Colorado, has been subjected to at least three separate Pleistocene glaciations, which from oldest to youngest are correlated with the Buffalo, Bull Lake, and Pinedale glaciations of Blackwelder in the Wind River Mountains of Wyoming. In this area, deposits of the oldest glaciation are...
Geology of the Mayagüez area, Puerto Rico
Peter H. Mattson
1960, Bulletin of the Geological Society of America (71) 319-362
The Mayagüez area forms the southwestern corner of Puerto Rico, west of 67° W. and south of 18° 15' N. One-third of the 640 square kms is covered by thick alluvium. Unconformities separate a basal complex, two sequences of highly folded igneous and sedimentary rocks, and a younger sequence of gently...
The chief oxide-burgin area discoveries, East Tintic district, Utah; A case history
J.B. Bush, D.R. Cook, T. S. Lovering, H. T. Morris
1960, Economic Geology (55) 1507-1540
In 1955 exploration for base and precious metals was undertaken by Bear Creek Mining Company immediately north of the Main Tintic district, Utah. During the course of this work Bear Creek became interested in the East Tintic district, primarily as a result of the activities of the U.S. Geological Survey in...
The chief oxide-burgin area discoveries, East Tintic district, Utah; A case history
J.B. Bush, D.R. Cook, T. S. Lovering, H. T. Morris
1960, Economic Geology (55) 1116-1147
The Burgin shaft is in the Chief Oxide area of the E. Tintic district, Utah, and is about a mile E. of any previously known ore bodies; workings from it are currently developing a substantial amount of commercial Pb-Zn ore in several blind ore bodies...
Stratigraphic and geotectonic relationships in northern Vermont and southern Quebec
W. M. Cady
1960, Economic Geology (71) 531-576
Stratified rocks of early and middle Paleozoic age form a belt of northeast-trending anticlinoria and synclinoria of middle Paleozoic age, in northern Vermont and adjacent parts of southern Quebec. The foreland margin of this belt, in the Champlain and St. Lawrence valleys to the west, is cut by eastward-dipping thrust faults of...
Occurrence of strontium in the surface and ground waters of Champaign county, Ohio
A.J. Feulner, J.H. Hubble
1960, Economic Geology (55) 176-186
Naturally occurring strontium was found in both surface and ground waters during an investigation of the water resources of Champaign County, Ohio. The strontium is related to the presence of celestite (strontium sulfate) in rocks associated with evaporite deposition. The principal source of celestite in Ohio is in rocks of Late Silurian age. Celestite is present also in the glacial...
Geology and ground-water resources of the island of Kauai, Hawaii
Gordon A. Macdonald, Dan A. Davis, Doak C. Cox
1960, Bulletin 13
Kauai is one of the oldest, and is structurally the most complicated, of the Hawaiian Islands. Like the others, it consists principally of a huge shield volcano, built up from the sea floor by many thousands of thin flows of basaltic lava. The volume of the Kauai shield was on...
Earthquake fluctuations in wells in New Jersey
Charles R. Austin
1960, New Jersey Division of Water Policy and Supply Water Resources Circular 5
New Jersey is fortunate to be situated in a region that is relatively stable, geologically. For this reason scientists believe, on the basis of the best scientific evidence available, that the chances of New Jersey experiencing a major earthquake are very small. The last major earthquake on the east coast...
Geological investigations in the U12b.03 and U12b.04 tunnels, Nevada Test Site
W.H. Diment, V. R. Wilmarth, F. A. McKeown, D.D. Dickey, E. N. Hinrichs, T. Botinelly, C. H. Roach, F. M. Byers, C. C. Hawley, G. A. Izett, Alfred Clebsch
1959, Trace Elements Memorandum 996
The papers comprising the various parts of this report contain preliminary results of the U. S. Geological Survey investigations in the U12b.03 and U12b.04 tunnels at the Nevada Test Site, Nye County, Nevada (fig. 1). The geologic studies were undertaken to define the structural, chemical, mineralogic, and some of the...
Gravity and seismic exploration in Yucca Valley, Nevada test site, January-April, 1959
William H. Diment, D.L. Healey, J. C. Roller
1959, Trace Elements Investigations 545
The thickness of the alluvial and tuffaceous deposits that overlie bedrock in Yucca Valley has been inferred from gravity and seismic measurements. Preliminary interpretations indicate that these deposits are thickest in a narrow north-trending trough in the eastern part of the valley. The gravity data delineate a buried north-trending ridge...
Ground-water resources of the Oakland Park area of eastern Broward County, Florida
C. B. Sherwood
1959, Florida Geological Survey Report of Investigations 20
The Biscayne aquifer is the source of all fresh ground water in the Oakland Park area of eastern Broward County, Florida. This aquifer extends from the land surface to more than 215 feet below mean sea level and is composed chiefly of sandy marine limestone, calcareous sandstone, and beds of...
Geological Survey investigations in the U12b.01 tunnel, Nevada Test Site
William H. Diment, V.R. Wilmarth, F. A. McKeown, D.D. Dickey, T. Botinelly, E. N. Hinrichs, C. H. Roach, F. M. Byers, G. A. Izett, G. R. Johnson
1959, Trace Elements Memorandum 998
The U12b.01 tunnel is part of the U12b (Rainier) tunnel system driven northwestward from the east slope of Rainier Mesa (figs. 1 and 2). Geologic and geophysical studies in this tunnel were conducted by the U.S. Geological Survey on behalf of the Albuquerque Operations Office of the Atomic Energy Commission....
Geology of the State of Morelos and contiguous areas in south-central Mexico
Carl F. Fries
1959, Open-File Report 59-41
The area described lies in south-central Mexico and embraces all but the southeastern corner and easternmost border of the State of Moreles, the second smallest State in the Mexican Republic. It includes small contiguous parts of the State of Mexico, in the northeastern corner, and of the State of Guerrero...
Iron-ore resources of the United States including Alaska and Puerto Rico, 1955
Martha S. Carr, Carl E. Dutton
1959, Bulletin 1082-C
The importance of iron ore, the basic raw material of steel, as a fundamental mineral, resource is shown by the fact that about 100 million long tons of steel is used annually in the economy of the United States, as compared with a combined total of about 5 million long...
Surface waters of Illinois River basin in Arkansas and Oklahoma
L.L. Laine
1959, Open-File Report 59-76
The estimated runoff from the Illinois River basin of 1,660 square miles has averaged 1,160,000 acre-feet per year during the water years 1938-56, equivalent to an average annual runoff depth of 13.1 inches. About 47 percent of the streamflow is contributed from drainage in Arkansas, where an average of 550,000...
