茫崖石棉矿是我国大型超基性岩型温石棉矿床。温石棉作为一种矿物在宏观上可以是纤维状的,也可以是非纤维状的。但是,作为工业矿物的温石棉都是呈纤维状的。作者对茫崖温石棉进行了纤维X光照相,揭示了其结构特征,鉴定了温石棉的多型,测定了温石棉2M_(c1)和20_(rc1)的含量百分比,在个别样品中发现有极少量的副温石棉,一些样品中发现有Povlen型温石棉,这是在我国的温石棉纤维中首次找到Povlen型温石棉。
Mangya astronomical Mangya mine is China’s large ultra-basaltic rock chrysotile mineral deposits. Chrysotile as a mineral macroscopically can be fibrous, it can be non-fibrous. However, chrysotile as an industrial mineral is fibrous. The author carried out fiber X-ray photography of Mangya as-cast asbestos, revealed its structural characteristics, identified the polygamy of asbestos, and determined the content percentage of 2M_ (c1) and 20_ (rc1) in asbestos. A very small amount of petro-asbestos was found in some samples, and Povlen chrysotile was found in some samples. This is the first finding of Povlen chrysotile in chrysotile fibers in China.
