Calcium is a soft gray alkaline earth metal, and is the fifth most abundant element by mass in the Earth's crust. Calcium is also the fifth most abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Calcium is essential for living ...
incorporation is increasingly unfavorable in the order vaterite, calcite, and aragonite.•The theoretical 34S/32S isotopic fractionation between the different calcium carbonates is small.•The results support the use of CAS as a recorder of the isotopic composition of ancient seawater sulfate.关键...

the fifth most abundant element in the earth's crust (3.6 per cent), occurring esp as forms of calcium carbonate. It is an essential constituent of bones and teeth and is used as a deoxidizer in steel. Symbol: Ca; atomic no: 20; atomic wt: 40.078; valency: 2; relative density: 1.55...
CaSO4 is the chemical formula for calcium sulfate, which is a calcium salt that occurs naturally. Gypsum is the common name for the substance when it is in its dihydrate form, CaSO42H2O, which is a white or colorless powder. Tile, wallboard, lath, and a variety of plasters are all made...
which is used as a fertilizer. The phosphate is a major constituent of bone ash. The arsenate and the cyanide are used as insecticides. Calcium bicarbonate causes temporary hardness in water; calcium sulfate causes permanent hardness. Generally, calcium compounds show an orange or yellow-red color...
