摘要
北臧家疃膨润土矿赋存于石前庄组(K1ŝq)地层中,共划分3个矿层,矿层主要呈层状、似层状产出。矿石呈泥质结构、似流纹状构造、似层状构造、块状构造,主要由蒙脱石组成,蒙脱石平均含量53.23%。矿床内夹层主要为膨润土化流纹质角砾凝灰岩。经分析认为,该矿床为陆相火山沉积水解蚀变型矿床。
The Bentonite deposit in Beizangjiatong occurs in the Shiqianzhuang formation(K1ŝq),which is divided into three ore layers.The ore is of argillaceous structure,rhyolitic structure,layered structure and massive structure,and is mainly composed of montmorillonite with an average content of 53.23%.The interlayer in the deposit is mainly Bentonite rhyolitic breccia tuff.It is considered that the deposit is a continental volcanic-sedimentary-hydrolytic altered deposit.
