摘要
根据近年来对新疆库车前陆盆地及北部坳陷中生代主要储气层巴什基奇克组介形类、轮藻和孢粉化石的研究 ,认为该组主体的地质时代应为早白垩世中期。
The microfossils from the Bashijiqike Formation of Kuche Foreland Basin, Xinjiang have been classed as Latonia-Cypridea-Damonella ostracode assemblage, Aclistochara huihuibaoensis-Mesochara voluta-Sphaerochara charophyte assemblage, and Cicatricosisporites-Lygodiumsporites-Classopollis sporo-pollen assemblage. The former two assemblages are referred to the middle Early Cretaceous and the latter is referred to the Cretaceous, thus the age of the Bashijiqike Formation is middle Early Cretaceous, probably corresponding to the Barremian.
