| 摘 要： | 在北羌塘半岛湖地区前人划分的晚侏罗世索瓦组二段地层中,采集到属于早白垩世时代的古生物化石(Classopollis sp.Dicheiropollis etruscus、Senegalosporites sp.Steevesipollenites sp.),依据化石鉴定结果及区域岩石地层对比,将半岛湖地区原索瓦组二段厘定为早白垩世白龙冰河组。该套地层的厘定,对北羌塘盆地早白垩世时期沉积环境、古地理重建具有十分重要的意义。

| Abstract: | In Bandaohu area of north Qiangtang, the fossil of early Cretaceous Epoch was found in the strata of Suowa formation in late Jurassic which is divided by former researchers. According to the fossil identification result and regional lithostratigraphy comparison, the Bandaohu area is determined to be Bailong-binghe formation. The determination of this stratum will be very important for the rebuild of sedimentary environment and paleogeography of early Cretaceous Epoch in north Qiangtang basin. |
