摘要/Abstract

摘要： 辽宁省某膨润土矿被压覆，矿区出露地层为下白垩统义县组火山—沉积岩系，地层呈缓倾的单斜构造。压覆区揭露2条层状膨润土矿体，矿体均产于火山碎屑岩中，与围岩产状一致。矿石呈残余凝灰结构，含有少量残留火山碎屑物质。推断该矿床为安山质凝灰岩沉积水解型膨润土矿床。经阳离子交换性能测试、X射线衍射、胶质价和膨胀容测试，判断该膨润土为钙基膨润土，矿石物化性能中等—良好，具有广泛的应用前景。、

Abstract: The north part of a bentonite deposit is overlaid in Liaoning Province.The exposure strata in the deposit,as slight dipping angle monoclinal structure,are Lower Cretaceous Yixian formation volcanicsediment rocks.There are 2 bedding ore body in pyroclastic rocks in the overlaid area,whose occurrence are same to the tuff wall rocks.The ore is remnant tuff texture,and contain a few of volcano matters.The author infers the deposit is a andesitic tuff sedimenthydrolysis type bentonite deposit.According CEC,XRD,colloid index and swelling volume analysis,the ore is Cabentonite,and has wide application prospect.

Key words: bentonite deposit,geology character,physical and chemical properties
