摘　　要：龙泉山熔剂灰岩赋存于中奥陶统马家沟组六段地层中,属浅海相沉积的石灰岩矿床。矿区共圈定矿体1条,矿体厚度稳定,CaO平均质量分数为53.80%,工业类型为黑色冶金熔剂用。该区碳酸盐的生成环境是潮间带和浅海地带,为机械沉积、化学沉积和生物沉积共同作用形成的沉积矿床,后经怀远运动和晋冀鲁豫运动,华北地台整体上升为陆,遭受剥蚀,直至晚石炭世才逐渐又遭受海浸。含矿地层为奥陶系马家沟组六段,含矿岩系为泥晶灰岩、豹皮状灰岩。The Longquanshan flux limestone deposit occurs in the sixth member of the Middle Ordovician Majiagou formation and belongs to the shallow marine sedimentary limestone deposit.One ore body was delineated in the mining area,the thickness of the ore body was stable,the average CaO mass fraction was 53.80%,and the industrial type was black metallurgical flux.The carbonate formation environment in this area is intertidal zone and shallow sea zone,which is a sedimentary deposit formed by the combined action of mechanical,chemical and biological sedimentation.After the Huaiyuan Movement and the Jin-Ji-Lu-Yu Movement,the north China platform as a whole rose to the land,it was not until the late carboniferous that it was gradually eroded back into the sea.The sixth member of Majiagou formation of ordovician is ore-bearing strata,and the ore-bearing rock series is micrite limestone and leopard-skin limestone.
