摘要
驼背山锑矿为一低温热液型矿床,矿体呈层状、似层状、扁豆状赋存于硅化破碎内,矿源层为上寒武统地层。矿区内构造活动较强,自晋宁期经历了多阶段多期次构造运动,通过对矿区内控矿构造解析发现,矿体产状随燕山早期构造所形成的褶皱形态的变化而变化,显示了典型的受背斜构造控制的后生矿床面貌,且燕山早期构造运动所形成的硅化破碎带是矿区的主要控矿构造,说明驼背山锑矿的形成受燕山早期构造运动的影响明显,形成时代应为燕山早期。
Tuobeishan antimony deposit is a low temperature hydrothermal vein type deposit,the ore body is lamellar,quasi-lamellar and bean reserved within silicified fractured belts,and the source of the mineral is upper Cambrain strata.Since Jinning period,the area has been through multi-stages and multi-periods tectonic movement.The shape of the ore body is changing with the fold,which indicates the deposit is a typical epigenetic deposit.The silicified fractured belts formed by early Yanshan movement is the main ore-controlling structure,which shows that the early Yanshan movement has significantly influenced the forming of the deposit and the ore forming age should be early Yanshan period.
