| 摘 要： | 朱碌科地区花岗质岩石侵位时间为二叠-三叠纪.按岩石谱系单位划分原则,由早到晚划分为中官营子和榆树林子两个超单元,前者由西窑单元、二道沟单元组成,后者由李台子、碾盘山和敖包山单元组成.岩浆成因类型为介于"I"型和"S"型花岗岩之间的过渡类型.它们均形成于造山晚期构造环境,与南蒙古复合造山作用有直接关系.

| Abstract: | The granitic rocks in Zhuluke area,Western Liaoning,emplaced during Late Hercynian Indosinian cycle,with Rb Sr isochronal dating age of 226.8～ 260 Ma.According to the classification principles of lithological lineage units,the granitic rocks may be divided (in descending order)into Zhongguanyingzi (including Xiyao and Erdaogou units)and Yushulinzi (including Litaizi,Nianpanshan and Aobaoshan units)super units.The magma evolved from intermediate to acid in nature.Genetically,they are the transition between I type and S type granites,formed in the tectonic environment of late orogenic epoch,directly related to the South Mongolian compound orogeny. |
