刚果(金)希图鲁外围物化探找矿应用

Application of geophysicaland geochemical prospection in the peripheral area of Hituru in D.R.Congo

希图鲁铜矿位于刚果(金)东南部加丹加省利卡西南部,本次工作区位于希图鲁铜矿的东南。该区的磁法工作快速、有效地划分了地层、构造、含矿层等找矿标志,圈定了找矿靶区;化探工作有效地对物探异常性质进行了划分,即矿致异常与非矿异常,进一步缩小靶区。可见,物化探异常为下步工程验证提供了重要支撑。

The working area is in southeastern area of Hituru Cu deposit which is located in the south of Likasi in southeast Province,Katanga in D.R.Congo.The magnetic survey works conducted in this area defined the prospecting clues like strata,structures and ore-bearing horizons and block out target area for prospectingin a fast and effective fashion.The geochemical prospection works further downsized the target area by effectively dividing the geophysical anomalies into anomalies related to mineralization and anomalies not related to mineralization.It is thus obvious that the geophysical and geochemical anomalies provide important support for engineering verification.
