在我国,由粗粒高岭石等组成的硬质耐火粘土矿床,根据所含有机质(黑色)及晶粒组合的不同可以分为两种类型: 1.粗晶高岭石硬质粘土。常含少量有机质,外观呈黑色,俗称“黑砂石”。有的采矿工人称为“砂锅石”。(这有如W.D.Keller所说的采矿工人称高岭石硬质粘土(粒细)为燧石粘土(flint Clay)一样)。其产出一般与煤系地层有关,在国外早有报导,但一般无工业价值。而在我国的不少地区“黑砂石”具有工业价值。它越来越受到有关方面的重视和利用。五十年代笔者曾从沉积岩石学角度强调其研究的重要性与工业价值。还认为其成因可能为胶体或机械搬运碎屑高岭石粘土的沼泽沉积,在石
In China, hard refractory clay deposits composed of coarse kaolinite, etc., can be divided into two types according to the organic matter (black) contained and the grain combination: 1. Crude kaolinite hard clay. Often contain a small amount of organic matter, the appearance of black, commonly known as “black sandstone.” Some miners called “casserole stone.” (This is similar to that of W.D. Keller in that miners call kaolinite hard clay (flint) flint clay). Its output is generally related to coal strata, has been reported abroad, but generally no industrial value. In many areas of our country, “black sandstone” has industrial value. It is getting more and more attention and use by relevant parties. In the 1950s, I emphasized the importance and the industrial value of the research from the perspective of sedimentary petrology. It is also believed that the cause may be colloidal or mechanical handling clastic kaolinite clay swamp deposition in the stone
