Geochemical balance of a small watershed and its geomorphic implications
E.T. Cleaves, A.E. Godfrey, O.P. Bricker
1970, Geological Society of America Bulletin (81) 3015-3032
A detailed input-output study of a small forested watershed draining the Wissahickon Formation in the Piedmont of Maryland revealed that chemical solution is five times as effective in removing material as is mechanical erosion. Solution weathering removes 16.9 tons/sq mi/yr of material compared with 3.2 tons/sq mi/yr by mechanical erosion....

Similarities, differences, and some genetic problems of the Wyoming and Colorado plateau types of uranium deposits in sandstone
R. P. Fischer
1970, Economic Geology (65) 778-784
Uranium deposits of the Wyoming roll type and the Colorado Plateau peneconcordant type are the principal domestic resources of uranium. Both types occur in lenticular sandstone beds of continental origin, have a similar suite of elements and minerals, are associated with mildly altered rock, and...
Saline groundwater resources of the conterminous United States
J. H. Feth
1970, Water Resources Research (6) 1454-1457
Saline water is arbitrarily defined as water containing more than 1000 milligrams per liter of dissolved solids. Saline ground water is known to underlie about two‐thirds of the 48 states. Locally, aquifers yield saline ground water in profuse quantities, some of which is used by industry, particularly for cooling. Generally,...
Brines and interstitial brackish water in drill cores from the deep Gulf of Mexico
F.T. Manheim, F.L. Sayles
1970, Science (170) 57-61
Marked increases in interstitial salinity occur in two drill holes located in the Gulf of Mexico at a water depth of more than 3500 meters. The increases probably arose through diffusion of salt from buried evaporites. In one hole, however, brackish water was encountered on penetrating the oil-permeated cap rock...
A progress report: Water conservation by removal of phreatophytes
Richard C. Culler
1970, Eos, Transactions, American Geophysical Union (51) 684-689
Evapotranspiration from the flood plain of a major river depletes the water contributed from upstream areas of the watershed. This depletion can be significant in arid regions where water supplies are inadequate. Phreatophyte control offers a method of reducing the evapotranspiration and thus increases the water available...
Nature and origin of early and late cherts in the Leadville Limestone, Colorado
Norman G. Banks
1970, Bulletin of the Geological Society of America (81) 3033-3048
Two generations of chert have been observed in the Mississippian Leadville Limestone of west-central Colorado: (1) an early chert inferred to have precipitated from hypersaline marine waters of high pH after those waters seeped into carbonate muds prior to final burial and lithification of the carbonate; and (2) a late...
Control methods for snail-borne zoonoses
G. L. Hoffman
1970, Journal of Wildlife Diseases (6) 262-265
All trematodes which cause infections and diseases in humans (zoonoses) require snails for their first intermediate host. Some have additional intermediate hosts such as crustaceans, fishes and frogs.In this paper I have discussed the use of various procedures for controlling snail populations thereby reducing the population of trematodes whose cercariae...
Deuterium: Natural variations used as a biological tracer
J.D. Gleason, I. Friedman
1970, Science (169) 1085-1086
The suggestion is made that isotope tracing be carried out by monitoring the natural variations in deuterium concentrations. As an example, the natural variations in deuterium concentrations between food and water collected in Illinois and food and water collected in Colorado were used to determine the residence time of water...
A re-evaluation of basalt-obsidian relations at East Lake Fissure, Newberry Caldera, Oregon
Michael W. Higgins, Aaron C. Waters
1970, Bulletin of the Geological Society of America (81) 2835-2842
Andesite scoria, agglutinate, and small flows formed by thin lava gushes that erupted from East Lake Fissure on the north wall of Newberry Caldera carry numerous inclusions of platy rhyolite, partly melted platy rhyolite, and frothy obsidian. This association of obsidian and “basalt” has been...
A look at the Hudson River estuary
Mark W. Buaby, Kenneth I. Darmer
1970, Journal of the American Water Resources Association (JAWRA) (6) 802-812
This paper provides background information on the effect of tide waves upon the movement of water in the Hudson River estuary. Computations based on records from three continuous stage recorders and current-meter discharge measurements made throughout a tidal cycle show that peak discharge rates in the...
Saline ground-water resources of the Tularosa Basin, New Mexico
J. S. McLean

This report describes the location, extent, and quality of saline ground water in the Tularosa Basin, a north-trending elongated, intermontane, desert basin in south-central New Mexico. There are no through-flowing streams; runoff from the bordering mountains flows to ephemeral lakes in the center of the basin. Fresh-water supplies in the Tularosa...
An outbreak of fowl cholera in waterfowl on the Chesapeake Bay
L. N. Locke, V. Stotts, G. Wolfhard
1970, Journal of Wildlife Diseases (6) 404-407
An outbreak of fowl cholera (Pasteurella multocida infection) occurred in waterfowl wintering on the Chesapeake Bay during February to March 1970. Losses were primarily confined to sea ducks: oldsquaws (Clangula hyemalis), white-winged scoters (Melanitta deglandi), golden-eyes (Bucephala clangula), and buffleheads (Bucephala albeola)....

Comparison of chemical hydrogeology of the carbonate peninsulas of Florida and Yucatan
W. Back, B.B. Hanshaw
1970, Journal of Hydrology (10) 330-368
Aquifers of the peninsulas of Florida and northern Yucatan are Tertiary marine carbonate formations showing many lithologic and faunal similarities. In addition, the tropical to subtropical climates of the two areas are similar, each having annual rainfall of about 1000 to 1500 mm.Despite similarities in these fundamental controls, contrasts in...
Metamorphic waters from the Pacific tectonic belt of the west coast of the United States
I. Barnes
1970, Science (168) 973-975
Waters unusually rich in ammonia, boron, carbon dioxide, hydrogen sulfide, and hydrocarbons are found in more than 100 localities along the Pacific coast of the United States. The waters are believed to be products of low-grade metamorphism of marine sediments. The marine sedimentary rocks would have to be tectonically emplaced...
