摘要
红透山式铜-锌矿床形成于太古代克拉通裂谷槽盆中海底火山喷发-沉积环境。因此,矿床的空间展布严格受特定的含矿岩系所控制。槽盆构造中的岩层褶皱构造最发育,矿床赋存在具多期褶皱构造叠加的大型同倾向形褶皱内,褶皱的层间虚脱是控矿有利构造空间,可以借此预测矿体侧伏方向及赋存部位。
The Hongtoushan copper-zinc deposit was formed in submarine volcanic eruptional-sedimentary environment in Archean intracratonic rift trough. Therefore, the spatial distribution of deposit is strictly controlled by specific ore bearing rock series. Fold is the most developed struture through deformation process of the strata in the trough basins. Deposits are located in large homoclinal synformal fold possessing multiperiodic and tectonic overprint. Interstratified detachment of fold is the most favorable tectonic ore-controlling space. It can be used to forecast the orebody's pitching direction and host position.
