These factors include variations in stable isotopic fractionation factors, the influence of local-scale Ca cycling on Ca isotopic gradients in carbonate settings, carbonate dissolution and reprecipitation, and the relationship between the Ca isotopic composition of seawater and mineral phases that record the secular evolution of seawater chemistry.
Calcium magnesium acetate (CMA), suggested formula CaMg 2 (C 2 H 3 O 2) 6, is an emerging bulk chemical. Calcium hydride, CaH 2, is an effective reducing agent at high temperatures and has been used to reduce inorganic oxides to their metals. Ordinary glass, soda-lime glass, is a complex mixture of silicates, chiefly those of sodium and calcium.
