Abstract : the nearshore around the nanhui spit is a transitional zonebetween the yangtze estuary and the hangzhou bay with complicated dynamic conditions , sediment transport , sedimentological processes and morphological evolution 文摘:南汇咀近岸水域位于长江口和杭州湾的交汇带，其动力条件、泥沙运移、沉积过程和地貌演变复杂。

Sedimentological and provenance data from tuchengzi formation in nuyingzi - goujiadian basin provide information about the links between erosional unroofing of adjacent thrust sheets and deposition within the basin . through field mapping , measured sections , and sedimentological analysis , we arrived at the following conclusions : 1 通过野外填图、实测地层剖面及室内分析工作，取得了如下主要成果和认识： 1 、土城子组主要由一套分选性和磨圆度都很差的碳酸盐质砾岩构成。

The stratigraphic sequences and sedimentological characteristics indicate that the main body of the bayan har basin is composed of triassic flysch sediments deposited in a foreland basin during the triassic . in the study of jinshajiang orogenic belt , in the applying archipelago theory and particular anatomies to basin analysis in this orogeny , the model of jinshajiang archipelago mountain building and basin building is set up . the orogenic - sedimentology and sedimentary basin analysis system is printed archipelago paleogeography any more 在金沙江造山带研究中，将多岛弧盆理论应用于这个造山带的沉积盆地分析研究中，对金沙江多岛弧盆造山带进行了详细解剖，建立金沙江多岛弧盆系造山造盆的模式，进一步发展造山带沉积学和沉积盆地分析理论体系。
