| 摘 要： | 20世纪80年代以来,在塔里木盆地西北部柯坪—巴楚地区发现了许多志留纪脊椎动物化石,其中包括无颌类、软骨鱼类等。这些化石的发现和深入研究揭示了塔里木盆地志留纪时期的古地理位置及其格局,进一步确定了塔里木陆块在该时期的古生物地理区应属于塔里木-扬子古脊椎动物生物地理区系。记述了采自塔里木盆地中心2个钻井岩心中的3件早志留世脊椎动物化石,其中1件化石为无颌类的新科、新属、新种。同时对志留纪时期塔里木陆块的沉积特征、古环境进行了分析和探讨。上述研究为油气勘探提供了有价值的科学依据。

| Abstract: | Since the 1980s, the Silurian vertebrate fossils including agnathans, chondrichthans and placoderms have been discovered in the Kalpin and Bachu area of Tarim Basin. These discoveries reveal the paleogeographic pattern of Tarim Basin in the Silurian period, and further suggest that the Tarim Block should belong to the Tarim-Yangtze Vertebrate Paleobiogeographic Province in Silurian. In this paper, the authors have described the vertebrate fossils from the cores of the boreholes and analyzed characteristics of the sedimentary facies and the paleoenvironment. The results provide scientific basis for the prospecting of oil and gas. |
