Rates of Calcium Carbonate Deposition by Deep-Sea Organisms, Molluscs and the Coral-Algae Association
The new data on strontium in deep-sea sediments indicate that though foraminifera and coccoliths may be low in strontium (1,200–1,800 p.p.m.) yet the deep-sea carbonate deposits are higher as a ...
