Textural and compositional data on ancient ooids and cements suggest the existence of an oscillating Phanerozoic temporal trend in non-skeletal carbonate mineralogy. The trend shows good correlation with eustatic–climatic oscillations proposed by others. The most likely mechanism appears to be plate-tectonically influenced oscillations in PCO2, the vapour pressure of CO2, rather than change in oceanic Mg/Ca ratio. 
Palaeoecological evidence for early aragonite dissolution in ancient calcite seas
It has been proposed that shallow carbonate seas of Upper Ordovician and Jurassic ages precipitated calcite as the primary calcium carbonate phase1–3, unlike such settings today. It is expected thatExpand

The ratio of magnesium to calcium in sea water is thought to have influenced the skeletal mineralogy of certain marine calcifiers throughout the Phanerozoic eon. A fresh look at old data suggestsExpand

During the Phanerozoic Eon, the mineralogies of nonskeletal marine cements and oolites have oscillated on a 100‐200 m.y. scale between aragonite ± high-Mg calcite (aragonite seas) and low-Mg calciteExpand
