I believe that the replacements resulted primarily from responses to pH changes, some of which took place within the sediments soon after deposition. The presence of CO2 probably is important in making possible the replacement of apatite by calcite. The study shows that given the right physio-chemical conditions, phosphate is a relatively mobile diagenetic constituent of sediments. This content is PDF only.
