Calcium silicate - Wikipedia
Properties. Calcium silicate is a white free-flowing powder. It can be derived from naturally occurring limestone and diatomaceous earth, a siliceous sedimentary rock. [citation needed] It is one of a group of compounds that can be produced by reacting calcium oxide and silica in various ratios e.g. 3CaO·SiO 2, Ca 3 SiO 5; 2CaO·SiO 2, Ca 2 SiO 4; 3CaO·2SiO 2, Ca 3 Si 2 O 7 and CaO·SiO 2 ...

Dolomite Mineral | Uses and Properties
Dolomite also serves as an oil and gas reservoir rock. During the conversion of calcite to dolomite, a volume reduction occurs. This can produce pore spaces in the rock that can be filled with oil or natural gas that migrate in as they are released from other rock units. This makes the dolomite a reservoir rock and a target of oil and gas drilling.
