Based on comparative studies on the utility of ICP, atomic absorption, and other techniques for the elemental analysis of geological samples the authors decided to pursue a...

Mobile laboratories are important to the exploration geochemist because they offer rapid chemical analyses of geologic materials in the field. This permits modification of the...

The average chemical metal composition of ferromanganese crusts was determined through various samples dredged during the L9-84-CP (R/V S.P. Lee) expedition by the United States...

Eighteen stations were occupied; 13 dredge hauls were collected on seamount, atoll, and island flanks and three box cores were taken from the sediment cap of an unnamed seamount...
