On the Devonian sequence stratigraphy of the north-west margin of the Yangtze platform in China

  • 摘要: 笔者在1:5万堡子坝幅、临江幅区域地质调查中,对扬子地台西北缘文县地区的泥盆纪地层进行了重新研究,共识别出个三级层序,层序均发育有TST和HST,前3阶层序缺乏LST和SMST,第四个层序发育SMST。通过对区内沉积层序的对比,初步建立了扬子西北缘泥盆纪地层格架,并对泥盆系区域地层格架作了探讨。
    Abstract: The strata of Devonian in the north-west border of Wengxian country of yangtze region was explored by the authors during the surveying of the 1:5000 Buziba sheet and Lingjiang sheet.The results of reseach show that it may be divided in to four three-order sequences.And each sequence exists TST and HST.The first three-sequence didn't find LST and SMST.The last one has SMST.After sedimentary sequences contrast of the region, the stratigraphic framework of Devonian was bas built and analycised at north-west border in yangtze region.
