总结了下扬子区晚泥盆世五通组典型的沉积构造，如风暴砾滩、冲洗交错层理、滩脊、三脊波痕、植物化石及遗迹化石埋藏相特征等。全定量分析了泥岩类的主化学组成及微量元素，其主化学组成具有高 Ｓｉ Ｏ２ 含量。高 Ｋ２ Ｏ／ Ｎａ２ Ｏ 比值，低 Ｍｇ Ｏ， Ｚｒ， Ｈｆ 组合特征显示近源沉积特征，与下伏下古生界有显著差别， Ｂ， Ｇａ ， Ｂａ， Ｓｒ， Ｒｂ等元素反映出滨海及海陆交互的沉积环境。综合分析沉积构造、沉积地球化学及区域地质特征，认为五通组形成于弧后前陆盆地，其沉积过程是一个海侵过程，这一大地构造背景一直延续到早石炭世末。
The typical sedimentary structures of the Late Paleozoic Wutong Formation in the Lower Yangtze region are summarized, such as storm gravel beach, rinsed staggered bedding, beach ridges, trigeminal wave marks, plant fossils and the burial facies of trace fossils. The main chemical compositions and trace elements of mudstone are quantitatively analyzed, and their main chemical compositions have high Si O2 content. The combination of high K2 O / Na2 O ratios and low Mg O, Zr and Hf compositions show near-source sedimentary features that are significantly different from the lower Paleozoic, with elements such as B, Ga, Ba, Sr, and Rb reflecting coastal and marine Interactive depositional environment. Comprehensive analysis of sedimentary structure, sedimentary geochemistry and regional geological characteristics, that Wutong formation in the arc foreland basin, the deposition process is a transgressive process, the tectonic setting of this earth has been extended to the end of the early Carboniferous.
