摘要
水东铅锌矿床位于六盘水裂陷槽北东面,黔中隆起南西缘,为水东地区重要的铅锌矿床。其断裂构造发育主要为北东向组和北西向组,矿体赋存于北西向组断裂中,受构造和岩性控制明显。成矿时代应主要为印支-燕山期,于是建立了在构造力驱动下,热液沿断层上升至灯影组上部白云岩受到屏蔽层阻隔,形成断层中铅锌矿体,同时热液发生侧向运移形成围岩脉状矿体的成矿模式。
The Shuidong Pb-Zn deposit is located in the northeast of the Liupanshui rift trough and the southwestern margin of the Central Guizhou Uplift. It is an important lead-zinc deposit in the Shuidong region. The fault structure developed mainly in the North-East and North-West Formations, and the orebodies are located in the faults of the North-West Formation, which are controlled by the structure and lithology. The metallogenic age should be mainly in the Indosinian-Yanshanian period. This paper establishes that under the drive of structural forces, hydrothermal fluids rise along the fault to the dolomite above the Dengying Formation and are shielded by the shielding layer, forming the lead-zinc ore body in the fault, and the hydrothermal occurrence side. The metallogenic model of the vein-shaped orebody of the surrounding rock formed by migration.
