山东青州王家辇-南王孔地区水泥用石灰岩矿地质特征分析

Analysis on Geological Characteristics of Cement Using Limestone in Wangjianian-Nanwangkong Area in Qingzhou County of Shandong Province

王家辇-南王孔地区水泥用灰岩矿位于青州市西北10km处。区内第四系广布,以大站组为主,含矿地层为奥陶纪马家沟群北庵庄组微晶灰岩、泥质条带灰岩,呈单斜形式产出,矿层延伸稳定。区内构造以断裂构造为主,断裂只对矿体有局部的位移,以及岩石的破碎,对矿体、矿石质量基本没有影响。矿石自然类型为微晶灰岩型和条带状灰岩型。工业类型为水泥用灰岩,成矿类型为浅海相沉积矿床。

Wangjianian- Nanwangkong cement using limestone deposit is located in 10km northwest of Qingzhou city. Quaternary strata are distributed widely in this area. Dazhan group is major strata. Ore - bearing strata are micrite limestone, argillaceous strip of Ordovician Majiagou group. It occurred in the form of monoclinic output, and strata extended stably. Structures in this area are fault structures majorly. Faluts caused regional displacement of fractures and broken rocks. It had no effect on the quality of ore bodies. Natural ore types are micrite and banded limestone. Industry type is cement using limestone. The metallogenic type is shallow marine facies sedimentary deposit.
