摘要
阐述了晚元古代温都尔庙群是区内金成矿有利的矿源层,其分布地带发现了金矿(化)集中区,金矿(化)体主要分布于该岩群与加里东期、华力西期花岗岩,石英闪长岩接触部位,并受控于糜棱岩带,后又叠加了燕山期花岗岩及次火山岩成矿活动,形成构造破碎蚀变岩型、石英脉型及次火山热液型金矿。指出该地区只要有温都尔庙岩群分布,加之叠加有不同期次的岩浆岩及有利的构造,就有可能找到新的金矿床。
To the south of Mandulatu Town of Sunitezhuo Qi in the Xilinhaote terrene on north margin of North China platform, accumulated gold mineralization has been found in Wenduermiao group of late Archean era. The main gold ores occur in the contect of the group with the Caledonian and Variscan granites and quartz diorites and controlled by mylonite zone and superimposed by Yanshanian granites and sub-volcanic rocks, forming fracture-altered type, quartz vein type and sub-volcanic hydrothermal type gold deposit which shows greater potential for further exploration. New gold deposits may be found if this group occurs along with the superimposed magmatites of various periods in a favourable structure in the area.
