智利圣地亚哥市迈普铜矿地质特征及找矿标志

Geological Characteristics and Prospecting Signs of the Maipu Copper Deposit in Santiago,Chile

迈普矿区位于美洲大陆西缘的安第斯褶皱山系南美褶皱带,矿床形成于第三纪中新统,为受闪长玢岩(石英闪长玢岩)体控制的斑岩型铜矿床。笔者通过总结迈普铜矿区预查项目积累的地质、地球物理、地球化学资料成果,对矿床地质特征和控矿因素等进行研究,分析了迈普铜矿床的类型和该区找矿潜力,以期为区内进一步找矿提供参考。

The Maipu mining area is located in the South American fold belt of the Andean fold mountain system on the western margin of the American continent,the deposit is formed in the Miocene Tertiary and is a porphyry copper deposit controlled by diorite porphyrite(quartz diorite porphyry)body.By summarizing the results of the geological,geophysical and geochemical data accumulated by the Maipu copper mine prospective project,the author studied the geological characteristics and ore-controlling factors of the deposit,and analyzed the types of the Maipu copper deposit and the prospecting potential of the area,in order to provide reference for further prospecting in the area.
