摘要
满都拉地区地处达茂旗—白乃庙Cu-Au多金属成矿带,区内地层主要为古生界及中新生界,断裂构造主要为NE向、NW向及近WE向,岩浆岩以华力西晚期为主。区内铜矿床类型较丰富,有斑岩型、热液型和火山块状硫化物型。铜矿床主要产于上石炭统本巴图组及下二叠统大石寨组中,受NW向及近EW向断裂控制,与华力西岩浆活动密切相关。文章认为区域上近EW向的上石炭统—下二叠统火山岩-碎屑岩-碳酸盐岩系,是本区的最佳找矿地段,华力西晚期岩浆岩及其与地层的接触带是找矿的重要标志。
Mandula area is situated at Damaoqi-Bainaimiao Cu-Au polymetallic mineralization zone. Paleozoic and Mid-Cenozoic strata are mainly exposed and faults strikes mainly NE, NW and near WE. Late Variscan magmatic rock is dominant. Porphyry, hydrothermal and volcanogenic massive sulfide copper deposits occur in the region. The copper deposits are mainly located in Upper Carboniferous Benbatu formation and Lower Permian Dashizhai formation and controlled by NW and near EW faults. They are closely related to Late Variscan magmatism. Therefore, the EW-trending Upper Carboniferous-Lower Permian volcanic-clastic-carbonate rock series are the target for further prospecting and Late Variscan magmatic rocks and their contact zones with enclosing strata are important prospecting mark.
