摘要
系统采集并研究了塔里木盆地北缘库车坳陷库车河剖面阳霞组的双壳动物化石，讨论了化石组合特点及其地质时代，根据化石组合面貌、岩性和沉积特征以及剖面结构，认为阳霞组的时代应为早侏罗世晚期，与北缰地区的三工河组相当。
The Bivalia fossils collected from the Yangxia Formation in Kuche river section of the Northern margin of the Tarim Basin have been systematical studied in this paper, with a thorough discussion on fossil associations and their ages.
