摘要
马达加斯加作为非洲岛国具有较好的多金属成矿条件,本文针对安巴拉拉塔(Ambararata)地区特殊的地质情况,以在马达加斯中部地区寻找我国经济发展急需的金、镍、铜矿产为目标,寻找以超基性有关的镍矿床、以花岗斑岩有关的铜金矿床。本文在采用地质测量与物化探及遥感综合找矿方法开展预查工作,初步查明区内地层岩石、构造、蚀变及矿化等特征的基础上,分析其铜多金属成矿地质条件,希望能为下一步地质工作提供参考。
As an African island country,Madagascar has good polymetallic ore-forming conditions.In view of the special geological conditions of ambararata region,this paper aims to find gold,nickel and copper deposits urgently needed by China's economic development in the central region of madagasi,and to find nickel deposits related to ultrabasicity and copper gold deposits related to granite porphyry.In this paper,the geological survey,geophysical and geochemical exploration and remote sensing comprehensive prospecting methods are used to carry out the pre investigation work,and the characteristics of strata rock,structure,alteration and mineralization in the area are preliminarily identified.On the basis of this,the geological conditions of copper polymetallic mineralization are analyzed,hoping to provide reference for the next geological work.
