|Abstract:||Twenty-seven surface samples of biogenic sediment, including radiolarian,
nannofossil, and foraminiferal oozes from the Western Equatorial Pacific
have been analyzed for potassium, magnesium, iron, rubidium, strontium, barium,
chromium, cobalt, nickel, copper, and zinc by rapid instrumental techniques.
Interelement associations have been evaluated with the use of a computer-compiled
matrix of correlation coefficients. The variables considered include elemental
determinations, water depth, and percentage of calcium carbonate. The associations
calcium carbonate: strontium, potassium: rubidium, and barium: nickel:
copper may all be explained with regard to their mode of entry into the sediment.
The data indicate that organic fixation of metals is a significant process during the
deposition of Pacific Equatorial sediments, whereas contributions from other
sources, i.e., sorbed cations on the surfaces of clay~ and coprecipitation with iron
or manganese oxides, are effectively masked in most cases by high rates of biogenous
