| 中文摘要: |
| 通过对独山江寨地区下泥盆统丹林组、舒家坪组的石英砂岩、含砾砂岩的粒度分析，并结合上述两个地层组岩性组合和沉积构造特征，对该时期沉积环境进行了详细分析，识别出该地区下泥盆统为无障壁滨岸相的砂（砾）质高能海岸型沉积环境，层序特征具海岸沙丘-后滨（海滩砂脊）-前滨-临滨亚相的三个退积沉积旋回序列。 |

| By grading analyses of quartz sandstone and pebbly sandstone of Danlin formation and Shujiaping formation in Low Devonian in Jiangzhai area，according to the lithology association and sedimentary structural features in these area，the sedimentary environment in this period is analysed，it finds out Devonian in this area is sandy high energy coast sedimentary environment without barrier onshore facies，it has 3 retrogradate sedimentary cycle sequences：coast dune-backshore-foreshore-shore sub-facies |
