摘　　要：板年坡金矿床是近年勘查评价发现规模较大的卡林型金矿床,矿体赋存在构造蚀变体中,含矿岩石主要为强硅化氧化铁质岩屑砂砾岩和强硅化黏土岩,矿石具有显微鳞片结构、砂砾结构、交代结构,斑杂状构造和块状构造。矿物主要有岩屑、碎屑石英、胶结物石英、黏土、高岭石、褐铁矿、白云母、电气石等重矿物,以及碳酸盐矿物。矿区内金成矿受赖子山背斜及其次级背斜、层间滑脱构造与气液隐爆共同控制,加强气液隐爆对金成矿控制作用的研究对于进一步找矿具有指导意义。Bannianpo Gold Deposit is a large-scale Carlin-type gold deposit discovered through exploration and evaluation in recent years.The ore body is hosted in structural alteration bodies,and the ore-bearing rocks are mainly intensely silicified iron oxide rock debris sand conglomerate and intensely silicified clay rock.The ore has microscopic scale structure,sand conglomerate structure,metasomatic structure,taxitic structure,and block structure.The minerals mainly include heavy minerals such as rock debris,detrital quartz,cementitious quartz,clay,kaolinite,limonite,muscovite,and tourmaline,as well as carbonate minerals.The gold mineralization in the mining area is jointly controlled by the Laizishan anticline and its secondary anticline,interlayer detachment structure,and gas-liquid crypto explosion.Strengthening the research on the control effect of the gas-liquid crypto explosion on gold mineralization has a guiding significance for further exploration.
