| 摘 要： | 信江盆地是一个具有复式结构和复杂演化历史的中生代陆相盆地。通过对盆地地质特征及盆地建造特征等的研究，探讨了盆地类型、白垩纪盆地结构和盆地演化及主要地质过程；建立了晚三叠世-白垩纪信江盆地演化模式；总结了信江盆地地质作用过程中所蕴含的印支运动造山与成盆、早白垩世火山作用、晚白垩世膏盐沉积、晚白垩世风沙堆积、晚白垩世恐龙灾变、晚白垩世末盆地不均衡隆升和新近纪以来新构造运动对盆地改造等6大重要地质事件。

| Abstract: | Xinjiang basin is a Mesozoic terrestrial basin with a duplex that has undergone a sophisticated evolution history. Based on studying of characteristics of the basin geology and construct, the type, construction, evolution and other main geological processes of the basin have been discussed in this paper, the later Triassic - Cretaceous evolution model of Xinjiang basin has been proposed, and six significant geological events have been summarized including the building of mountain and formation of basin, the early Cretaceous volcanism, the latter Cretaceous gypsum deposition, sand storm accumulation, the catastrophe of the dinosaur, unbalanced rising of the basin at the end of latter Cretaceous and the modification of basin by the neotectonic movement since Neogene. |
