摘　　要：西秦岭地区是我国重要的金矿成矿带,格尔托金矿即位于这一产矿带上。文章以格尔托金矿为例阐明了西秦岭地区区域和矿床地质特征,论述了在矿区深部和外围找矿的广阔前景,建立了地质地球物理模型,然后在已知地质资料的基础上依据所建立的地质地球物理模型对成果资料进行科学合理的分析,经验证,在西秦岭地区运用高频电磁测深法进行金矿矿山深部和矿床外围探矿是有效的。The west Qinling area is an important metallogenic belt in China, where the Gertuo gold mine is located. This paper demonstrates the re- gional geology and deposit features of the West Qinling area taking the Gertuo gold mine as an example, discusses the prospecting potential in the deep and peripheral areas, and builds a geological-geophysical model. Based on this model, the existing exploration data from HTM surveys are analyzed in combi- nation with geological data available. It is proved that it is effective to apply HTM to prospecting of deep-seated and marginal blind orebodies in gold mines of the West Qinling area.
