摘　　要：通过对南天山南缘分布的花岗岩和火山岩的岩石学、岩石化学、稀土元素地球化学及同位素地质学等综合分析，作者首次提出并确认南天山晚古生代岩浆弧的存在，并且讨论了该岩浆弧的形成演化对塔里木盆地的油源物质、油气的成熟、迁移和圈闭的影响。Based on the geochemistry, REE geochemistry, isotope geochemistry of granite and volcanic rocks which spread in the southern margin of the southern Tianshan, the authors first propose and confirm that there is late Paleozoic magmatic are in the southern margin of the southern Tianshan, and discuss the evolution of the magmatic are and its effect on the development of oil and gas in Tarim basin.
