摘　　要：以板块构造理论为指导,中蒙合作完成中蒙边界地区1∶100万地质编图成果的基础上,对中蒙边界地区构造格架进行了统一厘定和划分。该区Ⅰ级构造单元主体隶属于中亚构造带的阿尔泰—兴蒙造山系,部分属塔里木—华北陆块区。阿尔泰—兴蒙造山系可划分为10个Ⅱ级、27个Ⅲ级和69个Ⅳ级构造单元。塔里木—华北陆块部分划分出2个Ⅱ级、2个Ⅲ级和4个Ⅳ级构造单元。这些不同级别的构造单元较全面地概括了中蒙边界地区的地质面貌。Guided by theories of plate tectonics and based on the result of geological map compilation （1∶1,000,000）, the authors have first divided the tectonic units in China-Mongolia border area. In this area, the main bodies of grade I tectonic units belong to the Altay-Xingmeng orogenic system of the Central Asian Orogenic belt, while the other parts belong to the Tarim-North Chinablock domain. The tectonic units include 10 gradeⅡunits, 27 gradeⅢunits, and 69 gradeⅣunits for the Altay-Xingmeng orogenic system, and include 2 gradeⅡunits, 2 gradeⅢunits and 4 gradeⅣunits for the part of Tarim-North China blocks in this area. These tectonic units comprehensively generalize the geological features of the China-Mongolia border area.
