摘要
滇西云龙锡矿床为岩浆期后热液矿床,其形成及分布主要受岩浆期后热液和断裂构造控制。在垂直方向上,矿床的地球化学分带极为明显,它是两次成矿热液形成的脉动分带和一次成矿热液形成的分异分带的综合结果。矿床分带与断裂构造活动密切相关。
The Yunlong tin deposit in west Yunnan is situated at the joint between the Qinghai-Tibet-Yunnan-Burma zeta-type tectonic system and the Sanjian longitudinal tectonic system. The deposit is of post-magmatic hydrothermal origin, and its formation and distribution are strictly controlled by post-magmatic hydrothermal activity and fractures.Obvious geochemical zoning is noticed in the deposit. The zonation is the combined result of pulsating zoning and differential zoning. The zoning in the deposit is chaely related to fracture initiation.
