摘　　要：在青藏高原上发现的几条板块缝合带 ,均能见到以基性超基性岩为主的蛇绿岩分布 ,它们中的多数在青藏高原中西部 1∶10 0万航磁图上都有不同程度的反映 ,按其分布特征大致可分为 3类 。Along several plate suture zones discovered in Qinghai?Tibet plateau, there are ophiolite complexes dominated by basic and ultrabasic rocks, most of which can be discerned to some extent in 1:1 000 000 Airborne Magnetic Map of Central and Western Qinghai?Tibet Plateau. According to their distribution, the authors have divided these ophiolites roughly into three types for reference in the work of recognizing suture zones.
