    Laboratory determinations have been made of the distribution coefficient of Sr in calcite. Chemical analyses of several deep- sea carbonate sediment sections and their associated porewaters demonstrate that these values are appropriate for use in diagenetic studies. The distribution of Sr in the pore waters and sediments has been modelled. It is concluded that recrystallization of these carbonates is essentially isochemical. Recrystallization of the bulk of the calcite in deep-sea sections is largely complete within the upper few hundred meters. These results have important implications for the study of oxygen isotopic compositions of foraminifers and coccoliths. A distribution coefficient of Mg in calcite sediments has been estimated. -from Authors distribution coefficient recrystallization isochemical oxygen isotopic compositions
