摘要
松辽盆地西南隆起区高力板镇西南首次发现晚白垩世叶肢介化石4属6种,包括:Estherites(Euestherites)cf.pulcherrimus Zhang et Chen、Estherites(Euestherites)sp.、Estherites sp.、Halysestheria biformis Zhang et Chen、Glyptostracus sp.、Dictyestheria sp.,确定这套地层为嫩江组.该地区嫩江组的发现,为建立松辽盆地西南隆起区地层系列奠定了基础,为下一步开展松辽盆地油气地质调查研究提供了有力支撑.
A total of 6 species of 4 genera conchostracan fossils have been first discovered in Gaoliban Town,southwest uplift of Songliao Basin,including Estherites(Euestherites)cf. pulcherrimus Zhang et Chen,Estherites(Euestherites)sp.,Estherites sp.,Halysestheria biformis Zhang et Chen,Glyptostracus sp. and Dictyestheria sp.,indicating the Late Cretaceous Nenjiang Formation in age. The discovery lays a foundation for the establishment of stratigraphic sequence in the southwest uplift of Songliao Basin and provides a strong support for further oil-gas geological survey and research in the area.
