摘要
焉耆盆地处于塔里木盆地与吐哈盆地之间,其中生代地层归属一直是个有争论的问题.本文采用多元地层研究方法,分析了南北疆古生物、沉积旋回、岩石学、构造演化等特征,初步认为焉耆盆地中生代地层属南疆型,兼具南、北双重特征.
Yanqi Basin is located between Tarim Basin and Tuha Basin, and the attribution of its Mesozoic stratigraphy has been a long dispute. By using a multi_element method of stratigraphy, this paper has discussed paleontology, sedimentary cycles, petrology and structural evolution in the northern and southern Xinjiang respectively, and it is suggested that the Mesozoic stratigraphy in Yanqi Basin is of the southern type and shows some features of the northern type.
