中文摘要:
      [摘 要]论述了在植被发育和地形恶劣的李子地区利用双频激电轴向偶极装置快速寻找金矿的应用成果,总结了岩石矿物电性参数特征和工作方案及工作装置。认为双频激电法仪及其工作时使用的轴向偶极装置在北秦岭金银多金属成矿带天水段高山林区寻找金属硫化物金矿床具有轻便、快速、成本低、效率高、效果好的优点。结合扫面异常规模,多极距剖面测量数据的有限元最优化法幅频率数字反演,可有效的获得激电异常的半定量解释。异常查证结果表明,激电异常体与金矿体之间有很好的对应关系,文中轻便激电的工作方案在地面工作条件困难的地区值得推广。
英文摘要:
      Abstract: This paper applies the dual-frequency IP method (Dipole-Dipole configration) to rapid prospecting of gold ores in the Lizi area of Gansu Province, and discusses the characteristics of the electrical parameters for different rock samples. The result shows that the dual-frequency IP method and the equipment can be utilized effectively in the difficult terrain and forest areas of the Tianshui section of the north Qinling Mountain. It owns advantages for prospecting the metal sulfide gold deposits with high efficiency, low cost and ideal results. The finite element optimization method of frequency digital inversion technology can effectively improve the shock of the abnormal inference and interpretation, and to determine its position in space. The anomaly verification shows that the anomalous bodies correspond to the gold ore bodies well, and this method is worthy to be popularized.
