摘要
作者对山东省黄县煤系地层的研究发现 ,该煤系地层中赋存 3层层位稳定 ,厚度 0 .5～ 2 .5 m的钠基、钠钙基膨润土矿矿层。进一步研究表明 ,该膨润土矿尤其是软质膨润土矿石质量优良 。
Based on study on Na bentonite layers in coal bearing series, the authors discoved that the bentonite ores especially soft bentonite ores are good in quality to develop and ultilize comprehensively for industry.
