摘要
赣西北港口地区晚寒武世重力流是一套再沉积的产物。沉积类型比较多样，可划分滑动沉积、碎石流沉积、颗粒流沉积，它们分别代表斜坡的上部、小、下部及底部。其中根据砾石堆积形态、含量又可分为高密度流及低密度碎石流。晚寒武世本区的大陆斜坡坡向呈北—南方向展布。这套重力流的发现，确定了本地区大陆斜坡位置，贯通了江南过渡区南西—北东方向展布的大陆斜坡，对中国华南地区晚寒武世的构造古地理控制作用及层序地层学研究均具有重要意义。
The late Cambrian gravity-flow sediments found in the Gangkou ar-ea,northwest Jiangxi can be divided into slide, debric flow(dominant)and grain folw sediments which would develop in the upper,middle,lowerand bottom parts of the slope respectively. In terms of the shape anddebric content of the debric flows,they can be subdivided into higher andlower slope of the stdy area in N-S direction, It is an important signi-ficance for the gravity-flow sediments discovered to reconstruct lateCambrian tectonic paleogeography and sequence stratigraphic characteri-stics in South China.
