摘要
梁河锡矿床是滇西锡矿带西亚带的主要的矿床类型之一。该矿床位于印度板块与欧亚板块碰撞带前缘的腾冲-梁河弧形构造的转折部位,东邻三江构造带。通过对矿床地质背景、矿床地质特征、控矿因素、成矿物质来源及矿床成因等研究,结果表明该矿床与喜山期的花岗岩岩浆活动有着密切的时空关系和成因联系,表明成矿物质来源于喜山期深部花岗岩浆,矿床属于与花岗岩岩浆活动有关的热液矿床。
The Lianghe Sn deposit is a large one in west Yunnan. The deposit lies in the hinge position of the Tengchong-Lianghe arcuate structure in front of the plate collision zone. The study of geological features, ore-control factors and ore material source indicates that the deposit is closely related with the Himalayan granite intrusion and belongs to hydrothermal deposit related to granitic magmatism.
