The role of diagenesis in shaping the geochemistry of the marine carbonate record
Carbonate sediments and rocks are valuable archives of Earth's past whose geochemical
compositions inform our understanding of Earth's surface evolution. Yet carbonates are also …

Oxygen isotope composition of the Phanerozoic ocean and a possible solution to the dolomite problem
The 18O/16O of calcite fossils increased by∼ 8‰ between the Cambrian and present. It has
long been controversial whether this change reflects evolution in the δ18O of seawater, or a …
