Dolostone方解石
Dolostone is a sedimentary rock in the class known as chemical sedimentary rocks. It is closely related to limestone, but includes magnesium in the form of calcium-magnesium carbonate. The main constituent is the mineral dolomite, CaMg(CO3)3. The main pathway to the formation of dolostone is thought to be the replacement of some of the calcium in limestone with magnesium. Dolostone deposits are mainly ancient rocks, giving time for the replacement process in limestone. 白云石是一种化学沉积岩类的沉积岩。它与石灰岩密切相关，但含有以钙镁碳酸盐形式存在的镁。主要成分是矿物白云石，化学式为CaMg(CO₃)₃。白云石的形成主要途径被认为是石灰岩中部分钙被镁替代。白云石矿床主要是古老的岩石，为石灰岩中的替代过程提供了时间。
