| 中文摘要: |
| 小秦岭金矿田是我国主要产金基地之一,目前已全面进入深层次的第二空间找矿阶段,直接找矿面临诸多制约因素,综合物探方法为刻画深部地质结构,从而间接寻找矿床提供了可能性。基于此在区内开展了1∶2.5万高精度航磁测量及1∶5万重力测量工作,对区内隐伏岩体及隐伏断裂的位置及数量进行了圈定,对其深部地质结构特征进行了系统研究；同时结合地质矿产等资料,圈定了重点找矿靶区6处,为进一步勘查工作提供了地质依据。 |
| 英文摘要: |
| Xiaoqinling gold field is one of the important base of gold production,who has now entered the second-stage ore prospecting stage in deep, Direct prospecting faces many constraints, Integrated geophysical methods provide the possibility for the characterization of deep geological structure, and thus indirectly to find deposits, Based on this, the 1∶25000 high-precision aeromagnetic surveys and 1∶50000 gravity measurements were carried out in the area, the location and number of hidden rock masses and hidden faults in the area were determined and the deep geological structure characteristics were systematically studied. In addition, combine with the data of geology and mineral, we has delineated the prospecting target and provided geological evidence for the next exploring. |
