山西省方山县东南30公里是新民石棉矿区所在,发现于55年。山西省支水县西北65公里是长树山矿区,发现于73年春。两矿区相距8公里,全区范围共计百余平方公里。该区处于吕梁隆起边缘之东南侧,太古代及元古代大理岩系较为发育,岩系变质程度较高,大理岩均受不同程度的蛇纹石石棉矿化,因此矿点遍及全区。以往由于地质工作较为薄弱,前人仅对新民矿区做过一般性的评述。自70年以来在我国石棉制品工业的不断发展下,促进了该地区的普查与勘探工作,并已取得令人可喜的成绩,目前该地区已成为我国东部长纤维石棉(特级块棉)的生产基地之一。
Fangshan County, Shanxi Province, 30 kilometers southeast of Xinmin asbestos mining area found in 55 years. 65 kilometers northwest of China’s Zhoushui County, Changshu Mountain mining area, found in the spring of 73. Two mines apart 8 km, the region a total of 100 square kilometers. The area is on the southeast edge of the Luliang uplift. The Archean and Proterozoic marble systems are well developed and have a high degree of metamorphism. The marble rocks are all mineralized by serpentine asbestos to varying extents. In the past, due to the relatively weak geological work, previous reviews made only a general review of Xinmin mining area. Since 70 years, with the continuous development of China’s asbestos products industry, it has promoted the census and exploration work in the region and has made gratifying achievements. At present, the region has become the production of long fiber asbestos (special block cotton) in the eastern part of our country One of the bases
