Plate tectonics and magmatic evolution
James Gilluly
1971, Bulletin of the Geological Society of America (82) 2383-2396
The validity of the general idea of plate tectonics is accepted; the magmas evolved along the spreading ridges are thought to be largely tholeiitic basalt, although alkalic olivine basalt and...
Protective pumping to reduce aquifer pollution, Glynn County, Georgia
Dean O. Gregg
1971, Groundwater (9) 21-29
Water-level declines in the principal artesian aquifer have created a head imbalance between the aquifer and an underlying brackish-water zone containing up to 4,550 mg/1 chloride. The brackish-water zone leaks brackish water into the aquifer through several breaks in a confining unit.A relief well tapping the brackish-water zone was drilled...

R. G. Coleman, Marvin A. Lanphere
1971, Bulletin of the Geological Society of America (82) 2397-2412
Isolated blocks of high-grade blueschist and amphibolite facies metamorphic rocks occur within the Jurassic and Cretaceous eugeosynclinal deposits of the Coast Ranges of southwestern Oregon and California. The blocks range in size from individual rock masses commonly 5 to 1,000 ft in diameter to a...
Continuous magnetic profiles near ground level as a means of discriminating and correlating rock units
M. F. Kane, D. S. Harwood, N. L. Hatch Jr.
1971, Bulletin of the Geological Society of America (82) 2449-2456
Continuous magnetic profiles were recorded by a truck-mounted magnetometer along road traverses over stratified metamorphic rocks and plutonic igneous rocks of the New England Appalachians. The records show a series of distinctive, highly detailed magnetic anomalies which closely reflect the nature and distribution of near-surface...

S.H. Zisk, M. H. Carr, H. Masursky, R.W. Shorthill, T.W. Thompson
1971, Science (173) 808-812
Recently completed high-resolution radar maps of the moon contain information on the decimeter-scale structure of the surface. When this information is combined with eclipse thermal-enhancement data and with high-resolution Lunar Orbiter photography, the surface morphology is revealed in some detail. A geological history for certain features and...
Geologic setting of the Apollo 14 samples

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...
Relations of folded dikes and Precambrian polyphase deformation, Gardner Lake area, Beartooth Mountains, Wyoming
Lawrence C. Rowan, Paul A. Mueller
1971, Bulletin of the Geological Society of America (82) 2177-2185
Two cross-cutting mafic dikes in the headwall of Gardner Lake in the eastern Beartooth Mountains, Wyoming, have structural relations with Archean migmatite and gneiss that suggest intrusion between deformational phases recognized in the eastern part of the range. Fabric data show that the older dike,...
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...
Evidence on the age mineralization in the of east of barite, zinc, and iron lower paleozoic rocks Tennessee
R.H. Carpenter, J.M. Fagan, H. Wedow Jr.
1971, Economic Geology (66) 792-798
Based on a study of minor occurrences of zinc, barite, and iron in East Tennessee, certain deposits are interpreted to have formed during early Middle Ordovician time. Principal lines of evidence supporting this age are: (1) the occurrence of barite, sphalerite, and pyrite associated with synsedimentary collapse breccias which span...
An early middle ordovician age for collapse breccias in the east Tennessee zinc districts as indicated by compaction and porosity features
W. T. Hill, H. Wedow Jr.
1971, Economic Geology (66) 725-734
The carbonate strata of the Lower Ordovician formations in the southern Appalachian Valley were probably considerably thicker, less compacted, and more porous and permeable in early Middle Ordovician time than they are now. Analysis of selected compaction features of rocks associated with the breccias of the East Tennessee zinc districts...
Models of mineralized solution-collapse structures from drilling statistics: An aid to exploration
H. Wedow Jr.
1971, Economic Geology (66) 770-776
Variations in thickness and metal content of selected stratigraphic units cut by drill holes in the East Tennessee zinc districts have been analyzed by regression techniques. Such analysis demonstrated that as the thickness of an underlying limestone unit is decreased chiefly by solution thinning, overlying fine-grained dolomite units increase in...
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...
