辽西葫芦岛市白杨村石英岩矿地质特征及开发利用前景

GEOLOGICAL CHARACTERISITCS AND EXPLOITATION PROSPECT OF THE BAIYANGCUN QUARTZITE DEPOSIT IN WESTERN LIAONING PROVINCE

葫芦岛市白杨村石英岩矿赋存于辽西笔架山向斜北翼,青白口系景儿峪组中.矿层呈单斜状东西向展布,为一连续的、厚度稳定的单一矿层.矿石类型以巨厚层、厚层灰白—白色石英岩为主,矿石质量特点是硅高碱低,是与辽西地区高碱水泥用灰岩相匹配的硅质原料矿.通过对白杨村石英岩矿床产出层位、矿床特征及高硅低碱的矿石质量特点进行分析,并针对辽西水泥用石灰岩碱高的实际情况,探讨了该矿床开发利用前景.

The Baiyangcun quartzite ore in Huludao City,Western Liaoning Province is hosted in the Jing＇eryu formation of Qingbaikou system on the north limb of the Bijiashan syncline.The continuous single ore bed with stable thickness is distributed in the monoclinic east-west direction.With the main type of thick or mega-thick grey-white quartzite,the ore is characterized by high silicon and low alkali,which is a matchable component of siliceous raw ore for high-alkali cement production together with the limestone from Western Liaoning.Combining the above analysis with the actual situation of the high-alkali cement-used limestone in Western Liaoning,the paper discusses the prospect of exploration and exploitation of the ore to provide a reference for local cement production.
