摘　　要：吉尔嘎郞图—乌兰陶勒盖地区处于内蒙古中段北部,区内侵入岩较为发育,侵入时代为晚泥盆世、晚石炭世和早二叠世。通过野外地质调查及取样测试,结合区域地质背景,分析了该地区岩体地质特征、岩石学特征和岩石成因类型。晚泥盆世侵入岩主体形成于挤压性质的火山弧构造环境,晚石炭世侵入岩、早二叠世侵入岩主体均形成于挤压性质的同碰撞构造环境。The Jiergalangtu—Wulantaolegai area is located in the northern part of the middle section of Inner Mongolia,where intrusive rocks are relatively developed,and the intrusive ages are late Devonian,late Carboniferous and early Permian.Through field geological investigation and sampling test,combined with regional geological background,the geological characteristics,petrological characteristics and petrogenetic types of the rock mass in this area were analyzed.The main body of the late Devonian intrusive rocks was formed in the compressional volcanic arc tectonic environment,while the main body of the late Carboniferous intrusive rocks and the early Permian intrusive rocks were formed in the compressional syn-collision tectonic environment.
