圌山珍珠岩沸石膨润土矿床的评价和开发,将使镇江圃山地区成为江苏省较有前景的新型建材和化工非金属矿产原料基地。一、矿床地质概况(一)地层矿区内地层简单。地表广泛出露圌山组火山岩,个别钻孔见上党组火山岩。1.自垩系下统圌山组火山岩自上而下分四个岩性段:第四岩性段(K_1c~4):主要为粗粒沉火山碎屑岩,次为碱质流纹岩、角砾熔和流
The evaluation and development of the Qiongshan pearlite zeolite bentonite deposit will make the Zhubu mountain area of Zhenjiang become the new material base of new building materials and chemical non-metallic mineral in Jiangsu Province. First, the geological overview of deposits (A) strata Strata within the mine area is simple. The surface is widely exposed volcanic rocks Dangshan group, a group of individual drilling to see the Shangdang volcanic rocks. 1. Since the Lower Cretaceous Volcanic rocks of the Dangshan Formation are divided into four lithologies from the top to the bottom: the fourth lithologic (K_1c ~ 4): mainly coarse-grained volcaniclastic rocks, and secondary to rhyolite , Boulder melting and flow
