This open-file report contains basic data on measurements and chemical analyses of ground water, logs of test holes, and summary information on selected logs for Finney County, Kans....

Most usable ground water in the predominantly mountainous Central Coastal Subregion occurs in alluvium-filled valleys and coastal plains and in deeper aquifers of Quaternary and Tertiary age. The intervening mountainous areas are underlain by consolidated sedimentary, igneous, and metamorphic rocks, mainly of Mesozoic age. These older rocks contain only small...

Deep untapped aquifers of late Pliocene age, which contain water having 1,000 to 2,000 milligrams per liter of dissolved solids, underlie most of the coastal part of Orange County. Inland from the Newport-Inglewood structural zone, the depth to the base of aquifers containing fresh water ranges from 1,000 to 2,500 feet...

The proposed crossing of the Willamette River at Lambert Bend involves a 2.3-mile-wide flood plain. Two of the three principal tangents of the crossing will include bridges that will span the main channel and an overflow channel of the river, as shown in figure 1, page 3. The Oregon State...

The oxygen isotope composition of both calcite and aragonite of the pelecypod Inoceramus is lighter than the composition of the aragonite of associated baculites and other cephalopods from the western interior region, the Gulf and Atlantic Coastal Plains, parts of Canada, and West Greenland. This difference cannot be explained by...

The most dramatic variations in pore water composition occurred in Holes 2 and 3 in the Gulf of Mexico. Both holes showed a strong increase in salinity with depth, evidently owing to diffusion from underlying salt bodies. However, on Challenger Knoll (Hole 2) a sharp drop in salinity was observed...

The Gowganda Formation is part of the thick Huronián sequence of Precambrian sedimentary rocks that crop out in central Ontario from Lake Superior to Quebec. Although it has long been considered to be glacial, recent work on submarine slump and turbidite deposits has reopened the question of its origin. This...

Calcium hydroxide waters issue from four partly serpentinized Alpine-type ultramafic bodies in the western United States. The occurrence of calcium-hydroxide-type water is restricted to fresh Alpine-type ultramafic rocks. The calcium hydroxide waters are unsaturated with Mg end-member olivine and pyroxene but supersaturated with Mg end-member brucite and serpentine and thus...

This study of longitudinal stream profiles of rivers of the Midcontinent (rivers tributary to the Mississippi) and Atlantic and East Gulf Slopes has revealed five types of longitudinal profiles: (1) Overall concave-upward profiles with or without long constant slope segments; (2) convex upward, for example, the Missouri River has a...

On 5 November 1967 Kilauea volcano began erupting lava from vents on the floor of its summit pit crater. Halemaumau, 170 meters deep. This eruption ended nearly 2 years of the quiescence that followed a short lived eruption on the east  rift zone of Kilauea in December 1965 (1). The...

The genesis of granitic igneous pegmatites is here considered in terms of a model conceived from results of field and laboratory studies and subsequently tested by means of experimental investigations. This model emphasizes the roles of water (and/or other relatively volatile substances), both as a dissolved constituent in granitic magmas...

The Mesozoic evolution of California is interpreted as dominated by the underflow of oceanic mantle beneath the continental margin. Underflow during part of Late Cretaceous time of more than 2000 km of the eastern Pacific plate seems required by the marine magnetic data. Correspondingly, varied oceanic environments—abyssal hill, island arc,...

Three samples of zircon from the St. Kevin Granite, northern Sawatch Range, Colorado, were analyzed for uranium, thorium, and lead content and for lead isotopic composition; the concentrated HNO3 leaches of the zircons were similarly analyzed. The concordia age on the zircons was interpreted to be 1420 ± 40 m.y., an...

Zectran® (4-dimethylamino-3,5-xylyl methycarbamate), all insecticide proposed for control of spruce budworm, Choristoneura fumiferana (Clemens), was tested against 16 species of pen-reared or captivity-acclimated animals to determine its toxicity and potential hazard to wildlife. The acute oral LD60 values in mg/kg were: lesser sandhill crane, Grus canadensis canadensis L.., 1.0-4.5; Canada goose, Branta canadensis L.., 2.64; mourning...

Lake eutrophication is an economic, recreational, and aesthetic problem that affects every lake of the world. Eutrophication is the natural process of lake aging, and progresses irrespective of man's activities. Pollution, however, can hasten the natural rate of aging and shorten the life expectancy of a body of water. The...

The principles controlling the equilibrium between the denser salty water and the lighter fresh water in coastal aquifers apply to carbonate as well as sand systems. However, under certain equilibrium conditions of fresh and salt water in parts of some carbonate aquifers unusual hydrologic phenomena result. Hydrologic conditions at Tarpon...

Kohala Mountain is regarded as the oldest volcano on the island of Hawaii. Potassium-argon ages on three lavas of the Hawi Volcanic Series, the youngest sequence of lavas on Kohala, range from 0.14 to 0.20m.y. and indicate that volcanism ceased in the very late Pleistocene....

Mean flow of a stream is usually computed from a continuous record of flow ai a gaging station. A less costly method consists of (1) estimating 12 individual monthly flows from one discharge measurement per month and a concurrent gaging station record on a nearby stream, using a...

Merumite was discovered with associated diamonds and gold in 1937 in gravels of the Merume River in Guyana. It was described as essentially a hydrous chromium oxide that contains more than 80 percent Cr2Oa. Milton and Chao in 1958 found it to be a complex aggregate, mainly eskolaite (Cr2Oa) with...
