| 摘 要： | 通过岩石学特征、接触关系、地质时代等详细研究,阿吾拉勒山阔尔库岩基可解体为早石炭世赛肯都鲁序列((石英)闪长岩-花岗闪长岩组合)和早二叠世阔尔库序列(二长花岗岩-正长花岗岩组合),两序列的同位素年龄分别为331Ma和281Ma.地质调查已证实,两序列间为侵入接触.赛肯都鲁序列为钙碱性岛弧成因,阔尔库序列为碱性同碰撞型或后造山型成因.阔尔库岩基的解体,不仅客观反映了岩浆的分布及活动特征,而且对丰富研究区的构造岩石组合和探讨大地构造演化有重要价值.

| Abstract: | The detail study on petrology,contact relationship,diagenetic epoch of granitic bodie shows that the Awulale Kuoerku batholith could be disintergrated into two intrusive series,one is early Carboniferous Saikendulu series(comosed of(quartz)diorite and granodiorite),another is early Permian Kuoerku series(comosed of adamellite and monzogranit). With isotope dating ages of 331 Ma and 281 Ma. Our regional geological exploring confirmed that there are intrusive contact relationship between the Saikendulu series and Kuoerku series. The petrogenesis of Saikendulu series is calc-alkline island arc,and the Kuoerku series is alkaline syn-collision or post-orogenic. So the disintergration of the Kuoerku batholith not only shows the geological features and facts of magmatic movements,but also enrich the significance and theoretical value in studying tectonic rock association and evolution in this region. |
