摘要
豫北地区广泛出露寒武系—奥陶系地层,熔剂用白云岩主要产于上寒武统三山子组二段(∈3s2)。南寺矿区熔剂用白云岩矿整体呈单斜层状产出,区内出露长度1370m,宽25~524m。矿石主要类型为中—粗晶白云岩,主要矿物成分为白云石,矿石中各组分含量符合熔剂用白云岩矿工业指标要求。矿床成因类型为浅滩相沉积型碳酸盐岩矿床。
In the Cambrian-Ordovician strata widely exposed in Northern Henan,flux-used dolomite is mainly produced in the upper Cambrian Sanshanzi Formation.Three dolomite ore-bodys generally present a monoclinal stratiform output,exposed 1370km and width 25~524m.The main ore type is Medium-coarse crystalline dolomite.The main mineral composition is dolomite.Mineral deposits meet the requirements of flux-used dolomite ore industry index.The genetic type of the deposit is a shallow facies.
