| 摘 要： | 在内蒙古苏尼特左旗南部,近年来发现了白音宝力道和巴彦哈尔等多处金矿床。白音宝力道金矿位于苏尼特左旗蛇绿混杂岩带北侧,而巴彦哈尔金矿位于该蛇绿混杂岩带西部。苏尼特左旗蛇绿混杂岩带被认为是西伯利亚板块与华北板块之间的苏尼特左旗贺根山缝合带的组成部分。通过综合研究认为,苏尼特左旗存在两种不同成因类型的金矿:一种是以白音宝力道金矿为代表的、与形成于早古生代岛弧的花岗斑岩有关的中温热液型金矿;另一种是以巴彦哈尔为代表的、与侵入于蛇绿混杂岩带中的晚古生代中晚期花岗斑岩有关的浅成低温热液型金矿。

| Abstract: | Quite a few gold deposits have been found recently in the southern Sonid Zuoqi, Inner Mongolia, such as the Bayan Bold, Bayan Har and others. The Bayan Bold gold deposit is located to the north of the Sonid Zuoqi ophiolitic melange belt, and the Bayan Har gold deposit is in the west of the belt, which is thought to be a part of the Sonid Zuoqi-Hegenshan suture zone between the southern margin of the Siberian plate and the northern margin of the North China plate. Based on a comprehensive study, the authors hold that there are two genetic types of gold deposits in Sonid Zuoqi. The Bayan Bold gold deposit, which is related to granite-porphyry formed in Early Paleozoic island arc environment, is of a mesothermal type. And the Bayan Har gold deposit, which is related to the granite-porphyry intruded in Sonid Zuoqi ophiolitic melange belt in the middle-late stage of the Late Paleozoic, is of an epithermal type. |
