摘要: 南天山发育有2条基性、超基性岩带,北侧一条沿中天山与南天山分界线汉滕格里—哈里克—干沟断裂带分布,南侧一条大致沿南天山主脊分布,2条基性、超基性岩带的岩石组合和地球化学特征表明它们是肢解的蛇绿岩残块(王作勋等,1990)。

Abstract: 40Ar/39Ar age data obtained in this study indicate that the ophiolite formed during late Silurian Period in South Tianshan, and collision between Middle Tianshan block and Tarim block took place during early Permian Period.Paleobiogeographic data suggest that the South Tianshan ancient ocean may have developed between Angara and Cathaysian flora provinces during Carboniferous Period.
