A lower paleozoic paleoaquifer; the Kingsport Formation and Mascot dolomite of Tennessee and southwest Virginia
Leonard D. Harris
1971, Economic Geology (66) 735-743
The Kingsport Formation (Lower Ordovician) in one section may be composed of two dominant rock types--limestone and medium to coarsely crystalline dolomite--whereas in an adjacent section, most of the formation may be largely composed of breccia. The breccia bodies, which are interpreted to be solution-collapse features, range in width from...
Banquet speech "Man's conquest of energy, its ecological and human consequences"
M. King Hubbert
1971, IEEE Transactions on Nuclear Science (18) 18-35
The world's energy resources suitable for power production are of two classes: (1) various channels of the continuous energy flux from extraterrestrial sources, and from the earth's interior, and (2) chemical, thermal, and nuclear energy stored in the outer part of the lithosphere and in the...
Evolution of thought on ore controls in east Tennessee
Robert A. Laurence
1971, Economic Geology (66) 696-700
All early students of the zinc and barite deposits of East Tennessee, noting the geographic coincidence of the principal mining area with complex late Paleozoic geologic structure, concluded that (1) the ore-bearing breccias were produced by Appalachian tectonic forces and that (2) mineralizing solutions gained...
Tertiary limestone aquifer system in the southeastern states
H. E. LeGrand, V. T. Stringfield
1971, Economic Geology (66) 701-709
The hydrogeologic history of the Tertiary limestone system of the Southeastern States is reconstructed, especially as it relates to circulation of ground water and the development of solution cavities. The development of these solution cavities resembles in many respects the development of cavities in carbonates...
A geochemical hypothesis for dolomitization by ground water
B.B. Hanshaw, W. Back, R.G. Deike
1971, Economic Geology (66) 710-724
Most modern disordered dolomite has been found in dynamic environments. However, solutions associated with modern dolomite formation do not have a common Mg/Ca ratio; the ratio ranges from about 3 to 100. Ground-water circulation may have a significant role in formation of regional dolomites; one of the primary requirements for...
Problems on the origin of ore deposits in the lower Ordovician formations of east Tennessee
W. T. Hill, J. E. McCormick, Helmuth Wedow Jr.
1971, Economic Geology (66) 799-804
Most recent workers in the East Tennessee zinc and barite districts are in general agreement that the host breccias were formed by solution-collapse processes in early Middle Ordovician time, probably in an ancient carbonate aquifer system of regional extent. There is little agreement, however, on...
Fluid-inclusion evidence on the environment of formation of mineral deposits of the southern Appalachian valley
Edwin Roedder
1971, Economic Geology (66) 777-791
Approximately 1,330 fluid inclusions were studied in samples of ore and gangue minerals from both massive ore and late-stage vugs from a series of Appalachian deposits and five active mines in the East Tennessee zinc districts. Most primary inclusions in sphalerite, fluorite, dolomite, and quartz...

Geochemistry of water
O.P. Bricker
1971, Eos, Transactions, American Geophysical Union (52) IUGG302-IUGG305
The quadrennium 1967–1970 has been a productive period in the field of water geochemistry. Field studies, laboratory investigations, and theoretical considerations have led to significant advances in our knowledge of the chemical behavior of natural waters and of the solid earth materials that contain them. A symposium on trace inorganics...
Erosion and sedimentation
Carl F. Nordin Jr.
1971, Eos Science News (52) 292-295
Research activities in erosion and sedimentation processes have expanded broadly during the past several years and have kept pace with generally accelerated developments in all phases of hydrology and water resources investigations....
Structure and petrology of the alpine-type peridotite at Burro Mountain, California, U.S.A.
R. A. Loney, G. R. Himmelberg, R. G. Coleman
1971, Economic Geology (12) 245-309
The alpine-type peridotite at Burro Mountain is a partially serpentinized harzburgite-dunite body approximately 2 km in diameter. It lies in a chaotic mélange derived from the Franciscan Formation (Upper Jurassic to Upper Cretaceous) of the southern Coast Ranges of California. The peridotite is bounded on the east by a vertical fault...
A chemical study of serpentinization — Burro Mountain, California
R. G. Coleman, T. E. Keith
1971, Journal of Petrology (12) 311-328
Serpentinized dunites and harzburgites from the Burro Mountain peridotite show no change in the ratio of iron and magnesia to silica when compared with the same ratio for the unserpentinized equivalents. The mineral assemblage resulting from serpentinization consists of lizardite-chrysotile, brucite, and magnetite and is determined by the original...

Water levels in carbonate rock terranes
H. E. LeGrand, V. T. Stringfield
1971, Groundwater (9) 4-10
Many subtle aspects of water levels in carbonate rocks need to be put in perspective even though hydrologists have recognized the fundamental value of characteristics of ground-water levels. The depth to the water table in carbonate rocks is controlled by local factors such as permeability and...
Nationwide study of the streamflow data program
R. W. Carter, M. A. Benson
1971, Journal of the American Water Resources Association (7) 383-385
During 1970 the Geological Survey conducted a study to evaluate the surface-water data collection program. Objectives were formulated, specific goals were set, a massive analysis of available data was made to determine the extent to which the present system enables the goals to be met, alternatives...
Elevation-relief ratio, hypsometric integral, and geomorphic area-altitude analysis
Richard J. Pike, Stephen E. Wilson
1971, Bulletin of the Geological Society of America (82) 1079-1083
Mathematical proof establishes identity of hypsometric integral and elevation-relief ratio, two quantitative topographic descriptors developed independently of one another for entirely different purposes. Operationally, values of both measures are in excellent agreement for arbitrarily bounded topographic samples, as well as for low-order fluvial watersheds. By...
Gold content of natural waters in Colorado
Arthur W. Gosling, E. A. Jenne, T. T. Chao
1971, Economic Geology (66) 309-313
Neutron activation analysis of 67 samples of water draining from gold-barren and gold-enriched sedimentary, igneous, and metamorphic rocks of the Colorado Front Range reveals a relatively small range in total gold content (nondetectable to 150 nanograms per liter). "Solute" gold concentrations were generally higher than...

A paleohydrologic model for mineralization of the White Pine copper deposit, northern Michigan
Walter S. White
1971, Economic Geology (66) 1-13
Pertinent physical properties of the upper Keweenawan rocks can be measured or inferred within a sufficiently narrow range to make the quantitative evaluation of various paleohydrologic models for the origin of the White Pine copper deposit feasible. The approach is illustrated here by calculations for...
Fluid inclusion studies on the porphyry-type ore deposits at Bingham, Utah, Butte, Montana, and Climax, Colorado
Edwin Roedder
1971, Economic Geology (66) 98-120
Data are given on the composition, temperature, pressure, and density of the hydrothermal fluids present in the central Cu-Mo core of the deposit at Bingham, Utah, and in its related but not necessarily coeval peripheral Pb-Zn deposits. These data are based on a study of...

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 6

1971, Initial reports of the Deep Sea Drilling Project (6) 811-821
Sediments from Leg 6 sites, west of the Hawaiian Islands, consisted primarily of various combinations of deep-sea biogenic oozes, volcanic ash, and its breakdown products. Pore fluids from most of the sites were similar in composition to present day ocean water, and in some sties almost identical. However, interstitial fluids...
