    新疆西昆仑加勒万河一带早二叠世菊石化石的发现及岩相古地理意义

    The discovery of Early Permian ammonite fossils in Galvan, West Kunlun, Xinjiang and its significance of lithofacies and palaeogeography

    • 摘要: 在新疆和田县西南峡谷一带的加勒万河谷地区早二叠世地层中首次发现Prostacheoceras cf.KongaraquenseArtinskia sp.和Agathiceras sp.菊石化石。这3种菊石化石的时代为乌拉尔期,代表了特提斯型菊石组合,与华南的栖霞组相当。其中,Prostacheoceras为特提斯类型的主要属,Artinskia为空谷阶的特征属,Agathiceras则为中石炭世—早二叠世的世界性分布属。此三者同时出现在加勒万河一带加温达坂组中,丰富了加温达坂组的化石资料,对恢复西昆仑地区的古地理和与其他区域生物地层对比提供了重要的化石依据。

       

      Abstract: It was the firt funded of the Prostacheoceras cf.Kongaraquense,Artinskia sp.,Agathiceras sp.ammonoid fossils in the Early Permian Strata in the Galvan Valley,Southwest Canyon area,Hotan,Xinjiang. The date of these three classes fossils is Cisuralian,which is equal to the date of Qixia Formation in the South China. The Prostacheoceras ammonoid is the main genus of Tethys type,while the Artinskia ammonoid is the special type of the Kungurian and the Agathiceras ammonoid is the global ammonite type in the Middle Carboniferous to Early Permian. Those three types ammonoid fossils which were funded in the Galvan area,enrich new fossil materials to the Jiawendaban Formation,and also provide important fossil evidences for the biostratigraphic correlation research of the West Kunlun.
