【摘要】：塔里木盆地西北緣阿合奇地區(qū)石炭系巴什索貢組研究程度較低,鮮有古生物化石的報道,其精確時代一直沒有確定。在該套地層中發(fā)現(xiàn)四射珊瑚化石共計10屬13種,床板珊瑚5屬8種。其中四射珊瑚中主要分子有Kueichouphyllum,Palaeosmilia,Dibunophyllum,Arachnolasma,Lithostrotion,根據(jù)珊瑚的垂向分布,建立了Kueichouphyllum-Palaeosmilia-Dibunophyllum組合帶,該組合帶可與前人在華南地區(qū)早石炭世地層中建立的Yuanophyllum帶進行對比,也能與鄰區(qū)及中國其他地方相同時期的珊瑚組合對比,進而確定其精確時代為石炭紀密西西比亞紀維憲期至德塢期早期。對該珊瑚動物群的生物古地理研究表明,該動物群具明顯的特提斯生物大區(qū)和中國北方大區(qū)的珊瑚分子特征,屬二者的混生帶。
[Abstract]:The Bashsogon formation of Carboniferous in the northwestern margin of the Tarim Basin is of low degree of study, and there are few reports of paleontological fossils, and its exact age has not been determined. A total of 10 genera, 13 species and 8 species of bedplate coral were found in this series. Among them, the main molecule in the tetracorals is Kueichouphyllum,Palaeosmilia,Dibunophyllum,Arachnolasma,Lithostrotion,. According to the vertical distribution of the coral, the Kueichouphyllum-Palaeosmilia-Dibunophyllum assemblage zone is established, which can be compared with the Yuanophyllum belt established by the predecessors in the early Carboniferous strata in South China. It can also be compared with the corals assemblages of the same period in neighboring areas and other parts of China, thus determining its precise age from the Carboniferous period from the Carboniferous to the early Devi period in Mississippi. The biogeogeographical study of the coral fauna shows that the fauna has obvious characteristics of coral molecules in the Tethys biota and the northern China region, which belong to the mixed zone of the two fauna.
