按照产出形式不同,中国主要的工业纤维蛇纹石石棉矿床可分为两个类型。即超基性岩型和碳酸盐岩型。应用各种X射线衍射研究方法对七个主要矿床的73个样品研究表明:中国具有6个纤维蛇纹石石棉变种,包括:斜纤维蛇纹石石棉,正纤维蛇纹石石棉,D_c型纤维蛇纹石石棉,副纤维蛇纹石石棉,波伏棱斜纤维蛇纹石石棉和波伏棱正纤维蛇纹石石棉。同时,作者查明了中国各主要纤维蛇纹石石棉矿床的石棉种属。以正纤维蛇纹石石棉为主并含有相对地较多的副纤维蛇纹石石棉的吉林集安石棉矿床,在世界上是一个罕见的特殊矿床。
According to the different forms of output, China’s major industrial fiber serpentine asbestos deposits can be divided into two types. Namely ultrabasic rock type and carbonate rock type. A total of 73 samples from seven major deposits were studied using various X-ray diffraction methods. The results show that there are 6 fiber serpentine asbestos varieties in China, including: skeletal serpentine asbestos fiber, orthopyroxene serpentine asbestos fiber, D_c fiber Serpentine asbestos, Vice fiber serpentine asbestos, Beveled rib skew fiber serpentine asbestos and Beveled edge fiber serpentine serpentine. Meanwhile, the authors identified asbestos in China’s major fiber serpentine asbestos deposits. The Jilin Ji’an asbestos deposit, which is dominated by positive fiber serpentine asbestos and contains relatively much parasite serpentine asbestos, is a rare special deposit in the world.
