摘要
以构造解析为基础.进行霍各乞铜多金属矿区M形叠加褶皱的几何学运动学和动力学解释,总结构造对矿体的控制规律:三个世代的褶皱、韧性断层及相匹配的面理大都是成矿期构造,起运矿和容矿作用,可以划分五种控矿类型;第二世代褶皱为主形变,控制地层与矿体的展布,它与第三世代褶皱叠加的复合部位是找矿的靶区.
On the basis of structural analysis, the article deals with geometrical characteristics and dynalmi, kinetic analyses of M-shaped superposed folds in Huogeqi copper polymetallic mining field, Inner Mongolia. The regularities of folds' controlling over ore bodies were summarized: The folds of three generations, ductile faults and derivative foliations mainly belong to mineral structures, acting as ore-carrying and ore-housing structures. In them, five types of ore-controlling structures can be identified. The folds of the second generation are the main deformation and they controll the distribution of strata and ore bodies; The locations of superposition between the folds of the second and the third generation are the new prospecting targets.
