摘　　要：以沉积学理论为指导,结合岩石学和矿物学等学科,通过对塔里木盆地岩相和重矿物类型和组合及其稳定性等的分析,详细探讨了塔里木盆地侏罗纪—白垩纪的岩相特征,并重建古气候的演化特征。塔里木盆地侏罗纪主要属于温暖湿润气候,晚侏罗纪后期到早白垩世属于干旱炎热气候。This paper,guided by sedimentary theory,combined with petrology and mineralogy,based on analysis of lithofacies,heavy minerals classifications,associations and their stability,discussed in detail the features of lithofacies in the Jurassic-Cretaceous Tarim Basin and reconstructed the paleoclimate evolution and concluded that the Tarim Basin changed from substantially warm and moist climate in Jurassic to arid and hot in late Jurassic and early Cretaceous.
