Aragonite and magnesium calcite are more soluble than normal calcite. 霰石和镁方解石,比普通方解石更容易溶解。
The calcium carbonate in corals or in the shells of other marine creatures comes in two distinct mineral forms: calcite and aragonite. 珊瑚或其他海洋生物外壳里的碳酸钙,包含两种完全不同的矿物形式:方解石和霰石。
The influx of carbon dioxide from the atmosphere has caused the saturation horizons for aragonite and calcite to shift closer to the surface by50 to200 meters compared with where they were positioned in the1800 s. 大气的二氧化碳汇入海中,已经导致方解石和霰石的饱和线往上移动,比1800年代更接近海面50~00公尺。
aragonite
[ noun ] a mineral form of crystalline calcium carbonate; dimorphic with calcite <noun.substance>
Aragonite \A*rag"o*nite\, n. [From Aragon, in Spain.] (Min.) A mineral identical in composition with calcite or carbonate of lime, but differing from it in its crystalline form and some of its physical characters. ※ ||
