| 摘 要： | 吉林省晚三叠世—早白垩世花岗岩类侵入活动十分频繁,依据区域地质构造的演化和相应的岩石组合及所获之测年资料,可划分出三大成因构造类型:裂解型;走滑型,包括走滑拉分—张裂亚型和走滑拉分—隆挤亚型;会聚型。不同成因构造类型常有自身的成矿特征,藉以指导矿产的普查与勘探工作。

| Abstract: | Late Triassic-early Cretaceous granites occurred widely in Jilin Province. According to their isotopic dating results,rock association and regional geologic background,these granites can be divided into three tectonic types：cracking type,stretch type （strick-slip pull to tensional fracture sub-type and uplifting and strick-slip pull-apart to squeezing sub-type）,and convergent type. Different tectonic types of granites exhibit different metallogenic characteristics,which might be contributed to mineral resources survey and exploration. |
