研究区位于孟加拉海扇,其沉积体南北延伸２８００～３０００ｋｍ,东西延伸８３０～１４３０ｋｍ。每年形成的悬浮沉积物通过河流输入该地区,海湾北部沉积物厚度大约为１６ｋｍ。该研究区内沉积速率变化很明显,海湾东部岩心１１（水深２７１２ｍ）附近的全新世沉积速率（４...
Located in the Bengal fan, the study area extends 2800 ~ 3000km north-south and 830 ~ 1430km east-west. Suspended sediments formed each year enter the area through rivers and the thickness of sediments in the northern part of the Gulf is about 16 km. The change of sedimentation rate in this study area is very obvious. The sedimentation rate of Holocene near core 11 (depth 2712m) in the Gulf
