河南镇平山王庄水泥用大理岩矿地质特征

Geological Characteristics of Marble Mine for Cement-used in Shanwangzhuang,Zhenping,Henan

河南镇平山王庄水泥用大理岩矿赋存于古元古代秦岭褶皱带断陷地槽区的秦岭群雁岭沟组地层中,该地层遭受了长期复杂的构造活动、变质作用,使含矿大理岩层产出特征比较复杂。本文总结了山王庄水泥用大理岩矿体规模、形态、产状、厚度和矿石质量以及品位变化等地质特征。综合分析认为秦岭群雁岭沟组地层具备寻找水泥用大理岩的地质条件。

The Shanwangzhuang cement marble in Zhenping,Henan,existed in the Yanlinggou formation of the Qinling group in the Paleoproterozoic Qinling fold belt trough area,which suffered from long-term and complicated tectonic activities and metamorphism,resulting in ore-bearing the production characteristics of marble layers are more complicated.This paper summarizes the geological characteristics such as the size,morphology,occurrence,thickness,ore quality and grade change of marble orebody for Shanwangzhuang cement.Comprehensive analysis suggests that the Yanlinggou formation of the Qinling group has the geological conditions to find marble with cement.
