摘要
河北省井陉县南王庄水泥用灰岩矿赋存于寒武系张夏组地层中,区内构造不发育,未见岩浆岩出露。矿层分布于张夏组一段、二段,共圈定三个矿层,矿层与地层产状一致,厚度稳定。矿石组分主要为方解石,矿石质量优良。矿床属于浅海相生物化学沉积石灰岩矿床,其产出明显受到地层层位的控制。
Nanwangzhuang limestone deposit for cement in Jingxing county,Hebei province is hosted in the Cambrian Zhangxia formation.The geological structure in this area is not developed and no magmatic rock is exposed.The ore bed is distributed in the first and second members of the Zhangxia formation,and three ore beds are delineated.The occurrence of the ore bed is consistent with that of the stratum,and the thickness is stable.The ore composition is mainly calcite,and the ore quality is excellent.The deposit belongs to the shallow marine biochemical sedimentary limestone deposit,and its occurrence is obviously controlled by the strata.
