| 中文摘要:[摘要]非洲刚果(金)是世界上铜钴储量最多的国家之一,其中刚果(金)南部的加丹加省是铜钴
矿带的重要矿区,本文介绍了激发极化法在加丹加省某地铜钴矿矿区的应用效果。在简要阐述矿区的
地质和地球物理特征的基础上,介绍了物探的工作方法与技术,重点对激电测深异常进行了推断解释。
通过在该区开展激电测深工作,圈定了与成矿有关的赤铁矿体的分布、大致埋藏深度,结合地质和遥感
资料,推测与证实了三条断裂构造的存在,为深入开展地质找矿工作提供了有利的依据,同时也取得了
方法技术的基础性成果,为今后在非洲地区开展电法工作积累了宝贵的经验。 |

| Abstract:Abstract:Congo(DRC) in Africa is one of the countries with largest reserves of copper-cobalt ore in the world. The Katanga Province in southern
Congo(DRC),is an important area of the copper-cobalt ore belt. This article presents the application effects of the induced polarization (IP) sounding
method to a copper-cobalt deposit in Katanga. Based on a brief description of geology and geophysical features of the deposit area,this paper introduces the
working method and technology of geophysical prospecting,especially the interpretation of anomalies from IP sounding. Through IP sounding work,the hem鄄
atite ore body distribution and rough buried depth are delineated. Combined with geological and remote sensing data,the presence of three faults is inferred
and confirmed. These results provide evidence for further geological prospecting. At the same time,basic methods and techniques have been tested which
offer valuable experiences for electrical surveys in African regions in the future. |
