| 摘 要： | 新疆哈密地区下泥盆统发育,南部图拉尔根地区下泥盆统为大南湖组,北部三道白杨沟地区为卓木巴斯套组。在大南湖组中共发现四射珊瑚2属5种,床板珊瑚7属12种,并建立四射珊瑚组合Syringaxon moriense和床板珊瑚组合Pseudofavosites giganteus;在卓木巴斯套组共发现四射珊瑚5属7种,床板珊瑚2属2种,并建立四射珊瑚组合Orthopaterophyllum junggarense和床板珊瑚组合Pachyfavosites junggarensis。通过珊瑚在地层中的分布及组合的时代对比,确定前者的时代为早泥盆世埃姆斯期早期,后者的时代为埃姆斯期中晚期。通过与国内外典型的早泥盆世埃姆斯期珊瑚动物群的对比,认为哈密地区的珊瑚动物具有典型的早泥盆世温带动物群特征,在生物古地理区系上属于北方大区准噶尔-兴安省。

| Abstract: | The Lower Devonian strata are well exposed in Hami area of Xinjiang. Lower Devonian Dananhu Formation is located in Tulargen of southern study area, whereas the Lower Devonian Zuomubasitaw Formation is located in northern study area, Sandaobaiyanggou area. 5 species belonging to 2 genus rugosa corals and 12 species belonging to 7 genus tabulate corals were discovered in Dananhu Formation. Thus, one rugosa coral assemblage, i.e., Syringaxon moriense assemblage, and one tabulata coral assemblage, i.e., Pseudofavosites giganteus assemblage, were established in this formation. Also, 7 genus 5 species rugosa corals and 2 genus 2 species tabulate corals were collected from Zuomubasite Formation, and one rugosa coral assemblage, i.e., Orthopaterophyllum junggarense assemblage and one tabulata coral assemblage, i.e., Pachyfavosites junggarensis assemblage, can be recognized. Based on the stratigraphic distribution of these coral fauna and their correlation with previous records, the authors hold that Dananhu Formation in Tulargen area is Early Emisan in age and Zuomubasitaw Formation in Sandaobaiyanggou area is Middle-Late Emisan in age, respectively. Furthermore, the characteristics of coral fauna indicate typical temperate fauna during Early Devonian in Hami area, belonging palaeobiogeographically to the Junggar-Dahuricia province in Boreal realm. |
