摘　　要：大磨曲家矿区位于招平断裂带的北东段,属于玲珑矿田的范畴。矿区主构造302号脉已探获333资源量50余t,从地质意义讲,其与相临的特大型东风金矿为同一金矿床。目前,东风金矿床主构造207号脉下盘的202-206脉带已探获金资源量近90 t,与207号脉资源量接近,说明其下盘次级构造有很大的资源潜力,据此分析认为,我区302号脉下盘的次级断裂同样可能有较大的找矿潜力。The Damoqujia gold deposit is located in the north of the Zhaoping fault belt. It is a part of the Linglong gold deposit. In the major structure, the gold vein 302, more than 50 tons gold resource is blocked out. In the eye of the geological meaning, the Damoqujia and Dongfeng gold deposit are one gold deposit. Nowadays, near 90 tons gold resource is blocked in gold vein 202 to 206 of vein 207 lower plate , the major structure. It nears the gold resource of vein 207. This shows that its lower plate possess the great potential. Base on this, the lower plate secondary faults of vein 302 also possess great resource potential.
