Burial diagenesis and subsequent alteration of chalk The Overall Diagenetic Pathway 

The depth distribution of the Sr/Ca ratios of the recrystallized calcites in these sediments was calculated from the Sr2+/Ca2+ concentrations in the pore waters and appropriate values of the strontium distribution coefficient as a function of temperature from 5-25°C, where 

Aside from Sr, the original biogenic components of calcareous oozes also contain variable and minor amounts of other elements, like Mg, Na and S, all of which affect the solubility of the biogenic phases. Magnesium is especially 

Larger crystals grow at the expense of smaller ones in the burial of a foraminiferal-nannofossil ooze. In particular, very small calcite crystals that comprise disaggregated coccoliths and the walls of foraminifera represent the most
