　　Calcite

　　The Fengshan area has abundant calcite resources. The preliminary exploration and reported reserves amount to 3 million tons. Testing has revealed the presence of isomorphic substitution elements such as Mn, Fe, Zn, Mg, Pb, Sr, Ba, Co, TR, etc.; when these reach certain levels, they can form varieties such as manganese calcite, iron calcite, zinc calcite, magnesium calcite, etc. In addition, the crystals often contain mechanical inclusions such as brucite, dolomite, iron hydroxides and oxides, sulfides, and quartz.
