徐州市贾汪区水泥用灰岩地质特征及找矿标志

Geological Characteristics and Prospecting Indicators of Cement Limestone in Jiawang Area, Xuzhou City

通过对贾汪区四个水泥用灰岩矿的对比,了解了贾汪区水泥用灰岩的地质特征。水泥用灰岩的赋矿层位主要为寒武系张夏组和崮山组下段。矿床构造特征随山体走势变化。矿石类型主要为鲕状灰岩、豹皮状灰岩和泥质条带状灰岩。经归纳总结,贾汪区水泥用灰岩的找矿标志主要有三个:地层标志、构造标志和地形标志。

Through the comparison of four cement limestone mines in Jiawang area, the geological characteristics of cement limestone in Jiawang area are obtained. The ore-bearing strata of cement limestone are mainly the lower part of the Cambrian Zhangxia Formation and the Gushan Formation. The structural characteristics of the deposit vary with the trend of the mountain. The ore types are mainly shale limestone, leopard skin limestone and argillaceous banded limestone. It is concluded that there are three main prospecting indicators for cement limestone in Jiawang area: stratigraphic signs, tectonic signs and topographical signs.
