I have compiled CaCO (sub 3) mass accumulation rates (MARs) for the period 0-25 Ma for 144 Deep Sea Drilling Project and Ocean Drilling Program drill sites in the Pacific in order to investigate the history of CaCO (sub 3) burial in the world's largest ocean basin. This is the first synthesis of data since the beginning of the Ocean Drilling Program. Sedimentation rates, CaCO (sub 3) contents, and bulk density were estimated for 0.5 Myr time intervals from 0 to 14 Ma and for 1 Myr time intervals from 14 to 25 Ma using mostly data from Initial Reports volumes. There is surprisingly little coherence between CaCO (sub 3) MAR time series from different Pacific regions, although regional patterns exist. A transition from high to low CaCO (sub 3) MAR from 23-20 Ma is the only event common to the entire Pacific Ocean. This event is found worldwide. (mod. journ. abst.)
