| 摘 要： | 在北羌塘盆地北部乌兰乌拉湖地区测制了多条晚侏罗世索瓦组剖面,讨论了该区索瓦组的岩性组合特征、沉积环境及空间变化规律.首次系统研究了索瓦组双壳类、层孔虫及珊瑚化石的组合特征及地理分布.建立了一个双壳类生物组合带,一个层孔虫组合和一个珊瑚组合.确定索瓦组的地质时代为晚侏罗世牛津期-基默里奇期.

| Abstract: | Several Upper Jurassic sections of Suowa Formation were measured in Ulan Ul lake area in the northern area of Northern Qiangtang Basin. The lithologic associations, sedimentary environments and their variation of Suowa Formation are discussed in this paper. It is for the first time to systematically study fossil associations and distribntion of bivalve, Stromatoporidea and Anthozoa in Suowa Formation. An assemblage zone and two associations of fossils are established. It is made sure that Suowa Formation belongs to Oxfordian - Kimmeridgian stage of late Jurassic. |
