摘要
辽宁省黑山县芳山镇膨润土矿体赋存于下白垩统义县组,矿区内共圈定出北(Ⅰ)、东南(Ⅱ)两条矿体,矿体呈透镜状或似层状产出,矿石类型属钙镁基膨润土。下白垩统义县组中酸性火山碎屑岩层位是找矿的有利部位。
Bentonite deposit in Fangshan town Heishan county of Liaoning province lies in lower Cretaceous Yixian formation.Two orebodies are delineated, which are occurred as north(Ⅰ)and southeast(Ⅱ). The ore bodies assumed like lenticular forms and stratoid. The ore type is Ca-Mg-base bentonite. The intermediate-acid pyro-clastic rock of the lower Cretaceous Yixian formation is the favourable prospecting area.
