摘要
界牌岭锡多金属矿床产于石炭系碳酸盐岩和泥岩、碎屑岩分布区中,区内北东、北西、东西向断裂发育,有浅成相花岗斑岩体产出,岩体接触带中,高温热液蚀变作用发育,锡多金属矿体有两种产状:沿构造裂隙产出的细脉带型矿体;沿层间裂隙产出的似层状矿体。矿石中锡含量0.12—3.38％,主要为锡石,硫化锡和胶态锡只占含锡量的2.88％。
Jiepailing tin-polymetallic ore deposit is found in the carbonate, mudrock and clastic rock of Carboniferous System distributing area. NE,NW and EW trend faults developped in the area, with the occurrence of supergenic phase granitic porphery. Hypo-and meso-thermal alteration developped along the contact zone. There are two modes of occurrence of tinpolymetallic orebodies, that is: veinlet zone type occurred along structural fracture; bedded one occurred along the interlayer fractures. The ore has tin content of 0.12—3.38％, composed mainly of cassiterite,the tin in sulfide and collide state takes only 2.88％ of total tin content.
