Interstitial water studies on small core samples, Deep Sea Drilling Project: Leg 10 Interstitial water studies on small core samples, Deep Sea Drilling Project: Leg 10

Leg 10 interstitial water analyses provide new indications of the distribution of rock salt beneath the floor of the Gulf of Mexico, both confirming areas previously indicated to be underlain by salt bodies and extending evidence of salt distribution to seismically featureless areas in the Sigsbee Knolls trend and Isthmian Embayment. The criterion for presence of salt at depth is a...

Red sea drillings Red sea drillings

Recent drilling in the Red Sea has shown that much of the basin is underlain by evaporites of a similar age to that of evaporites found in the Mediterranean Sea. These evaporites and their structural positions indicate that other brine areas are present - and, indeed, several others have been discovered.

Interstitial water studies on small core samples, leg 14 Interstitial water studies on small core samples, leg 14

The interstitial waters from the sediments cored on Leg 14 exhibit characteristic compositional trends with three important exceptions. At most of the sites, the changes in Na and Cl are very small while enrichment of Ca and Sr and depletion of Mg and SO4 is typical of patterns observed in similar types of sediment recovered on previous legs. At Sites 139 and 140, off the African coast...

Interstitial Water studies on small core samples, deep sea drilling project, leg XII Interstitial Water studies on small core samples, deep sea drilling project, leg XII

With the exception of Site 114, all interstitial waters in Leg 12 showed marked increases in calcium, which can be attributed to diagenetic dissolution and recrystallization of calcium carbonate, especially coccolith and foraminiferal tests. Magnesium loss may be due to either or both replacement of iron in clays or the dolomitization of calcium carbonate. The lowest sample from Site 113...

Interstitial water studies on small core samples, leg XI Interstitial water studies on small core samples, leg XI

The sediments cored at Sites 98, 99 and 100 are predominantly biogenic; those cored at Sites 101 through 106 are composed mainly of terrigenous material. As reported previously, most constituents in pore waters from the biogenic oozes exhibit minor changes in chemistry relative to sea water. In the terrigenous-hemipelagic sediments interstitial solutions initially of sea water...

Suspended matter in surface waters of the northern Gulf of Mexico Suspended matter in surface waters of the northern Gulf of Mexico

Analyses of about 200 surface water samples collected during late fall 1966 show that concentrations of suspended matter greater than 1 mg/liter were restricted to within a few kilometers off Florida, but extended more than 100 km off Louisiana and Texas. Suspensates from areas farther than 100 km from shore contained mainly combustible organic matter, part of which was attributable to...

Interstitial water studies on small core samples, Leg 9 Interstitial water studies on small core samples, Leg 9

The chemistry of the pore fluids obtained on Leg 9 is remarkable primarily in its constancy. Excepting silicon and strontium, only at one site do the concentrations of the major and minor constituents deviate notably from sea water concentrations (see Tables 1 and 2). The trends, or lack of them, seen in these samples have been discussed previously and only references will be given here...

Interstitial water studies on small core samples, deep sea drilling Project, leg 7 Interstitial water studies on small core samples, deep sea drilling Project, leg 7

The sediments cored on Leg 7 are predominantly deep sea biogenic oozes and chalks; only rarely were significant quantities of pelagic clays and volcanic detritus encountered. The biogenic sections include both siliceous and calcareous deposits. At three sites the drilling terminated in basalt, one of which (Site 62) is interpreted as being intrusive on the basis of intense alteration of...

Foreign literature and translations in earth science Foreign literature and translations in earth science

More than 50 percent of the total abstracted geologic literature is in Russian, followed by English at about 30 percent, and French, German, and Japanese from about 8 to 2 percent. Communist Chinese publications ceased as a result of the Cultural Revolution and have not resumed. Less than 2 percent of American earth scientists read and use Russian literature in the original to any...

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 8 Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 8

Leg 8 sites are dominated by siliceous-calcareous biogenic oozes having depositional rates of 0.1 to 1.5 cm/1000 years. Conservative constituents of pore fluids showed, as have cores from other pelagic areas of the Pacific, insignificant or marginally significant changes with depth and location. However, in Sites 70 and 71, calcium, magnesium and strontium showed major shifts in...

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

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 from Site 53 (Philippine Sea) showed changes in ionic...
