New analyses of 1,075 previously collected stream sediment samples, measuring more elements with better precision. Includes arsenic, gold, palladium, and platinum and 55 major, rare earth, and trace element concentrations.
New data for 366 previously collected stream-sediment samples, because recently developed analytical methods can detect additional elements of interest and have lower detection limits than the methods used when these samples were originally analyzed.
Magnetic susceptibility measured for 700 samples of drill core from thirteen drill holes in the porphyry copper-molybdenum deposit of the Stinkingwater mining district in the Absaroka Mountains, Wyoming
Nd and Pb isotopic analyses from stratigraphic sampling from Somma-Vesuvius volcanic complex, Italy, during the last 3550 years point to contributions from heterogeneous lithosphere, continental crust, and magma mixing.
The long-wavelength (50-2,500 km) content of the regional magnetic anomaly compilation was improved by utilizing a nearly homogeneous a nearly homogeneous set of NURE magnetic surveys flown from 1975 to 1981
