这项研究涉及来自恒河-雅鲁藏布江的河流沉积物的命运，恒河-雅鲁藏布江是世界上最大的河流沉积物来源。高分辨率地震剖面与将根据其确定Pb210和C14年代学的沉积物岩心相结合，将描绘出河口向海的大陆架上沉积物的分布和堆积速度。质地和矿物学研究将评估输送路径和沉积物来源。
英文摘要
This study addresses the fate of fluvial sediment derived from the Ganges-Brahmaputra River, the single largest fluvial sourceof sediment in the world. High-resolution seismic profiles,combined with sediment cores from which both Pb210 and C14 geochronologies will be determined, will delineate the distribution and rates of sediment accumulation on the continental shelf seaward of the river mouth. Textural and mineralogical studies will evaluate transport pathways as well as sediment sources.
