| 摘 要： | 加多措岩体因逆冲推覆断裂切割、肢解而分布于三个不同的逆冲推覆岩席之上，且产出形态多样。经对比研究，建立了岩石谱系单位；经条件分析，成岩时代及岩性对比，划分了四个单元，归并为一个超单元。探讨了成份极性特征，并确定甘孜－理塘结合带的俯冲方向是由东向西。

| Abstract: | Cut by a thrust,the Jiaduocuo granodiorite tonalite mass occurs as different forms on three nappe sheets The lithodemic units are established On the basis of lithogenetic age and litology,it is divided into four units which are incorporated into one superunit Make an approach to the compositional polarity from which it is concluded that the Garz Litang junction subducted westwards |
