| 摘 要： | 在陆相河湖沉积的八道湾组（早侏罗世）内，新发现一些海相瓣鳃类化石，表明当时准噶尔盆地在一短期内曾与海水相通，或者海水通过某一水系涌入该河湖区。从生态特征分析，当时可能为一泛滥平原。根据海相化石对化，化石产出层位八道湾组上部的时代可能属西湟缪尔期。

| Abstract: | Some marine bivalves were found in the Badaowan Formation(Early Jurassic) with continental lacustrine sediment, which indicates that Junggar basin used to be coneded with sea water in a short bine or the sea water emerged the lake. Analysis on the ecological characteristics,there was a flooded plain at that time. According to the correlation study of marine fossils, the occurence horizon of the fossil, the upper part of Badaowan Formation probably belongs to Xihuangmur Stage. |
