摘要
在对研究区实测声地层剖面资料进行分析解释的基础上,对比地质浅钻资料,将浅部地层划分为四个地震相单元,对研究区浅地层的沉积格架有了进一步的认识。对区内海底潮流沙脊、沙席、埋藏潮流沙脊、海底沙波等砂质地质体的地质特征有了较深入的了解,并对砂矿的物质来源、成因进行了讨论,揭示出本区砂体近源沉积、快速堆积的特点。
Based on the geological interpretation of sub-bottom profiling which was acquired in study area,The paper divided the shallow strata (or sub-strata) into 4 units with contrasting to drilled data,and have farther understanding of the frame of shallow strata in surveying area.Some geological structures which developed in the seafloor such as sand ridges,deposits of tidal channel,sand waves or mat,and those buried under the seafloor are studied in depth,and the discussion to origin of sand resource and supplying of sediments revealed that the sand bodies has characteristics of near-sources deposition and rapid accumulation.
