摘　　要：中蒙边界地区成矿区带划分是近年来该区成矿规律研究中的重要科学问题之一。以板块构造-地球动力学理论为指导,在中蒙合作完成的该区1∶100万建造-构造图和成矿规律图的基础上,对中蒙边界地区成矿区带进行了统一厘定和划分。该区Ⅰ级成矿域隶属于古亚洲成矿域和滨太平洋成矿域。古亚洲成矿域可划分为阿尔泰、准噶尔-南蒙古和塔里木3个成矿省、12个成矿带和21个成矿亚带。滨太平洋成矿域划分出大兴安岭和华北陆块2个成矿省、4个成矿带和15个成矿亚带。研究提出,蒙古的欧玉陶勒盖-查干苏布尔嘎大型-超大型斑岩型矿床成矿亚带向西与中国的东天山-北山成矿亚带相连,为该区寻找同类型斑岩型矿床指明了方向。The division of metallogenic belts in Sino-Mongolian border area has recently been one of the most important issues aimed at studying the metallogenic regularity. Based on the theories of plate tectonics-geodynamics and the results of informational-structural map and minerogenetic map（1∶1000000） which were completed by experts from Mongolia and China,this paper firstly provides a unified division of the metallogenic belts in this area. The metallogenic domains of grade I belong to the Paleo-Asian and the Marginal Pacific Metallogenic Domains in this area. The Paleo-Asian metallogenic domain includes 3 metallogenic provinces comprising Altay,Junggar-Southern Mongolia and Tarim metallogenic provinces,12 metallogenic belts and 21 sub-metallogenic belts,whereas the Marginal Pacific Metallogenic Domain includes 2 metallogenic provinces,4 metallogenic belts and 15 sub-metallogenic belts. In addition,this paper suggests that the western part of the sub-metallogenic belt of Oyu Tolgai-Chagan Subuerga largesuperlarge porphyry deposits in Mongolia is connected with the sub-metallogenic belt of the Chinese East Tianshan-Beishan submetallogenic belt,and this understanding provides the prospecting direction in search for porphyry deposits in this area.
