摘要
勐糯铅锌矿矿物组合较为简单,主要矿石矿物为方铅矿和闪锌矿,脉石矿物以方解石、石英和重晶石为主;矿石结构可分为沉积成岩期的原生结构、成岩后生期的交代充填结构、构造期的应力作用结构及表生期的氧化残余结构;矿石构造主要为沉积成岩特征构造及后期改造作用形成的构造;成矿期次可划分为沉积成岩期、成岩后生期、构造期、表生氧化期四个期次。
The mineral assemblage of Mengnuo Pb-Zn deposit is simple, metallic mineral mainly galenite and sphalerite, gangue mineral mainly calcite, quartz, barite. The ore texture can be divided into the original texture in sedimentation diagenesis period, metasomatosis filling texture in post-diagenesis period, stress texture in structure period and oxidation relict texture in epigenesis period; the main ore structure sedimentation diagenesis structure and the structure formed by later reformation; metallogenesis period can be divided into 4 periods, ie sedi-mentation diagenesis period, post-diagenesis period, structure period and epigenesist oxidation period.
