Potentiometric surface of the Lloyd aquifer on Long Island, New York, in January 1975
Charles A. Rich, Keith R. Prince, Anthony G. Spinello
1975, Report
A map showing the potentiometric surface of the Lloyd aquifer was drawn from water-level measurements made in January 1975. Altitude of the potentiometric surface ranged from more than 20 feet below mean sea level in Queens County to more than 40 feet above mean sea level in Suffolk County....
Geologic setting of Boulder 1, Station 2, Apollo 17 landing site
E.W. Wolfe
1975, The Moon (14) 307-314
Boulder 1 at Station 2 is one of three boulders sampled by Apollo 17 at the base of the South Massif, which rises 2.3 km above the floor of a linear valley interpreted as a graben formed by deformation related to the southern Serenitatis impact. The...
Origin of magnetite and pyrrhotite in carbonaceous chondrites
J.M. Herndon, M.W. Rowe, E.E. Larson, D.E. Watson
1975, Nature (253) 516-518
CARBONACEOUS chondrites, although comprising only about 2% of known meteorites, are extremely interesting for scientific investigation. Their mineral constitution, and the correspondence between their bulk chemical composition and the solar abundance of condensable elements, indicate that minimum chemical fractionation and thermal alteration have occurred. The mineral...
Recent sedimentary history of Lake Monona, Wisconsin
Gilbert C. Bortleson, G.F. Lee
1975, Water, Air, & Soil Pollution (4) 89-98
Chemical analyses from two short cores in Lake Monona show that pronounced changes in chemical stratigraphy have occurred since white man moved into Madison and southern Wisconsin and began modifying the area. Since the mid to late 1800's, there has been an appreciable increase in P,...
