By comprehensive analysis of the characteristics of formation and reconstruction, six tectonic belts in the northeast part of Junggar basin were divided: marginal obduction zone in Early Paleozoic(O1-2) ?melange mag-ma collision zone of late Paleozoic (D1) , volcanic arc-compression zone of Late Paleozoic (D1) , back-arc folded belt of Late Paleozoic (D2_3), marginal depression folded belt of Late Paleozoic (C1-P2) and foreland basin gentle anticline belt of Mesozioc era, etc. Since Paleozoic, twice evolution of extension-collision (closure)-nap-ping had happened, which show the distribution of north compression to south extension and the tectonic trans-port of north former to south later. Until the end of Permian period during Late Hercynian tectonic movement, the whole basin was folded and compressive napped. At last, according to the analysis results of structural fea-ture and evolution, it was suggested that more work should be done in favorable areas with well petroleum geo-logical conditions, such as Shuanjingzi marginal basin-anticline belt.
