| 摘 要： | 智利的区域地质和地球物理勘探的工作程度相对偏低,对矿区的地球物理资料的解释不够,矿床的分布特征了解得不透彻。笔者通过物探地面磁测和电磁法,对智利第一大区X矿区的地质特征与地球物理特征进行了综合分析,认为相对高磁或弱磁低阻异常带及其周围、深部是找矿的地球物理异常标志,本地区构造(破碎带)是下一步成矿规律的研究重点。地球物理方法对实际勘查工作具有指导意义。

| Abstract: | The regional geological and geophysical exploration work in Chile remains at relatively low level, the interpretation of mining area geophysical data is insufficient, and the distribution characteristics of ore deposits are not clearly known. The authors made a com- prehensive analysis of the geological and geophysical characteristics, and employed the geophysical ground magnetic and electromagnetic measuring method in the X ore district of the first region of Chile. It is held that the relatively high magnetic or weak magnetic low resistivity anomaly zone and its depth and surrounding areas are geophysical anomaly indicators for ore prospecting, and that the structure （ shatter zone） should be the focus in further study of the metallogenic regularity. Geophysical exploration methods are of guiding signif- icance in the practical exploration work. |
