| 摘 要： | 黑色高岭石粘土岩，是铜川王石凹煤矿石炭纪煤系地层顶部，五号煤层的上部一层稳定的煤矸石。经偏光显微镜及费氏台测试光性特征、化学试验及分析鉴定表明，这是一种由高岭石组成的，成分很纯、颗粒大、结晶良好的高岭石粘土岩。据微量元素含量分析，此高岭石系淡水沉积物。

| Abstract: | The black kaolinitic clay rock is a gangue from Wangshiwa coal mine in Tongchuan. It is located stably in upper part of the No. 5 coal layer at the top of carboniferous coal strata. According to the optical properties tested by polarizing microscope and Fedorov stage as well as chemical test and analysis, it is shown that the rock is a kind of kaolinitic clay rock composed of kaolin with pure composition, coarser grain, and very good crystallization. Minor element analysis demonstrates that is is freshwater sediment. |
