Abstract:
The upper Albian to Coniacian section (Cores 105 to 89) at Site 530 contains rare and poorly preserved coccoliths at a few levels and fine-fraction carbonate ("micarb") at all the levels studied. Dissolution ranking of the most resistant coccolith species is possible. Changes in the dissolution intensity resulting from variations in the organic carbon and carbonate input seem a likely explanation for changes in the relative abundance of fine-fraction carbonates types.
