位于陕南某地区的黑木林石棉矿床,产于自黑木林至峡口驿条带状超基性岩变质的蛇纹岩体内。矿区分四个矿段。杏树湾和长梁矿段构成一巨大透镜体,平均厚度200米,水平延长2400米,平均品位为4.247%。杏树湾矿段为蛇纹石石棉及纤维水镁石富集地段,长梁矿段为纤维水镁石富集地段。矿区内纤维水镁石总储量丰富。国外见有两类工业水镁石矿床。一为球状水镁石型,另一为水镁石与蛇纹石均匀嵌布型。陕南水镁石资源不同于以上两类。该
The Hemuilin asbestos deposit, located in a certain area of southern Shaanxi, is produced in serpentinite bodies of stratiform ultrabasic rocks metamorphic from Hei-linlin to Xiaokouyi. Mine is divided into four sections. Xingshuwan and Changliang mine section constitute a huge lens body, with an average thickness of 200 meters, extending 2,400 meters horizontally, with an average grade of 4.247%. The Xingshuwan ore section is serpentine asbestos and fiber brucite enrichment section, and Chang Liang ore section is fibrous brucite enrichment section. Mineral fiber brucite total reserves of rich. There are two types of industrial foreign brucite deposits abroad. One for the ball-type brucite, the other is brucite and serpentine evenly embedded type. South Shaanxi brucite resources are different from the above two categories. This
