您要查找的是不是:
- Early Devonian epoch 早泥盆世
- The geochronologic unit is belonged to Early Age of Middle Devonian Epoch,and correspond to Eifelicus Stage-Jiweite Stage,and is belo... 由于该套地层在黄哈吐地区为首次发现,对大地构造及地层区划等基础地质的研究有着重要意义。
- The geochronologic unit is belonged to Early Age of Middle Devonian Epoch,and correspond to Eifelicus Stage-Jiweite Stage,and is belonged to Daminshan Formation of Devonian system. 时代属于中泥盆世早期,大体相当于艾菲尔阶-吉维特阶,应归属为大民山组。
- Shujiaba Formation in the northern belt of Qinling mountains belongs to the Middle-late Devonian epoch with a total thickness over 2000 m. 西秦岭北带泥盆系舒家坝组属中晚泥盆世,地层总厚超过2000m。

- The paper presents a brief summary of current knowledge on the Early Devonian Posongchong flora, with its age, floral components and features discussed. 摘要简要回顾了目前云南早泥盆世坡松冲植物群的研究,论述了坡松冲植物群的时代、组成和性质。
- The Late Paleozoic volcanic rocks (from Early Devonian to Early Permian) were widely distributed in the south margin of the Altai Mountains. 阿尔泰山南缘晚古生代火山岩十分发育,从早泥盆世到早二叠世均有发育。
- The studied region may be divided into platform system,slope system,shelf system and basin system. The shelf system was developed in the Early Devonian to early Middle Devonian. 研究区可划分出四种沉积体系,即台地体系、台坡体系、陆棚体系、台盆体系,其中陆棚体系主要发育于早泥盆世至中泥盆世早期;
- From the Middle Silurian to the Early Devonian, no fossils were found in the EQM, which probably indicates that the EQM was a land and was connected with the North China Block. 在中志留世至早泥盆世,东秦岭未发现古生物化石,很可能为陆地,并与华北陆块联为一体。
- The long isolation in the different phytogeographical units( i.e. the northeastern Gondwana unit and south China subunit during the Early Devonian) and different environment may result in the evolution and diversify of numerous endemics. 不同古植物地理区的长期隔离(也就是,早泥盆世的东北冈瓦纳古植物地理区和华南亚区)和独特的环境可能是造成众多地方性分子演化分异的原因。
- These Devonian volcanics were resulted from the subduction of oceanic lithosphere basin (between Heiying Mountains and Hula Mountains) in south rim of South Tianshan to the north in early Devonian. 该套火山岩由于南天山南缘洋盆(黑英山-虎拉山间的洋盆)在早泥盆世中期向北俯冲而成。
