Abstract:
Gaozhuang Gold Deposit is a shear zone type epithermal deposit,the main character of mineralization and alteration is intense quartz-sericite,the shear zone controls orebodies as follows:shear zone controls quartz veins,a series of ringent crannys control gold-quartz vein,(grades structure system controling orebodies is controled by the smash segments which suffered the most strong distortion.Gold-quartz vein distribut in shear zone with“jalousie”mode.The metallogenesis is divided into two stages-endogenetic and exogenous formation,the former comprises four stages:sulfuret-short quartz-vein stage,magnetic pyrite-gold-quartz-vein stage,gold-pyrite-quartz-vein stage and quartz-carbonate one,and the second and the third are the main ore-metallogenic stages.Due to magnetic pyrite and pyrite have different capable to resist oxidation,the zonal weathering in exogenous stage has partial different from others.
Key words: shear zone type, gold deposit, geology-geochemical feature
