阐述本溪南芬区施家堡子石灰岩矿的地质特征,矿体分布特点,矿石类型为黑色冶金熔剂石灰岩(大理岩)和黑色冶金熔剂高镁石灰岩(白云质灰岩);黑色冶金熔剂石灰岩(大理岩):边界品位CaO≥48%,矿石为方解石大理岩和细晶灰岩,矿层以细晶灰岩为主;黑色冶金熔剂高镁石灰岩(白云质灰岩):边界品位CaO+MgO≥49%,矿石以白云质灰岩,粉晶灰岩为主。施家堡子石灰岩矿与东西展布北大山花岗岩体和北滚马岭花岗岩体关系密切,施家堡子石灰岩矿矿床显示出沉积接触热变质成因的特征。
This paper describes the geological characteristics and ore body distribution characteristics of the Shijiapuzi limestone mine in Bennupfen, Benxi. The ore types are black metallurgical flux limestone (marble) and black metallurgical flux high-magnesium limestone (dolomitic limestone), black metallurgical flux limestone Rock): the grade of CaO is ≥48%, the ore is calcite marble and fine-grained limestone, and the finely crystalline limestone is the main deposit; black metallurgical flux high-magnesium limestone (dolomitic limestone): the boundary grade CaO + MgO≥49 %, The ore to dolomitic limestone, pink crystal limestone. The Shijiapuzi limestone mine is closely related to the Beidashan granite body and the North-rolling Maling granite body in the east-west distribution. The Shijiapuzi limestone deposit shows the characteristics of the genesis of the sedimentary contact thermal metamorphism.
