摘 要：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,Dc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。
Abstract: The major industrial chrysotile deposits in China may be classified,according to mode of occurence, into twotypes, i.c. ultrabasic rocks type andcarbonatiter type. Using various metheds of X-ray diffraction, studies for 73 samples from 7 major chrysotile deposits are made. lt is shown that there are6 varieties of chrysotile in China, including clino-chrysotile, ortho-chryso-tile,Dc-type chrysotile., para-chrysotile, Povlen-clinochrysotile and Povlen-orthochrysotile. Meanwhile, the author makes sure that the variety ofchrysotile belongs to each major chrysotile deposit. The chrysotile depositin Jian, Jilin, which contains mainly ortochrysotile and more para-chryso-tile relatively, is a rare and special chrysotile deposit in the world.
