    Sedimentary Evolution and Geological Significance of the Dongsha Submarine Canyon in the Northern South China Sea

    • 摘要: 为揭示南海北部东沙海底峡谷沉积演化及其资源效应,利用高分辨率二维多道地震与多波束测深数据,对该峡谷中-上游段的沉积层序、地貌特征及沉积构型展开剖析.东沙海底峡谷上游段表现为6个分支峡谷,中游段则汇聚为2条主峡谷,峡谷头部广泛发育分支水道.峡谷中游段于早中新世晚期开始发育,处于岩浆岩体和构造凸起之间;上游段分支峡谷形成于晚中新世以来,其与峡谷头部分支水道的形成分别受断裂体系和底流作用影响较大.东沙海底峡谷演化分为3个阶段:(1)早中新世晚期-中中新世,峡谷初始发育阶段;(2)晚中新世,峡谷拓展阶段;(3)上新世以来,现代峡谷发育阶段.东沙海底峡谷向马尼拉海沟提供了充足的富有机质沉积物,构成了马尼拉海沟增生楔天然气水合物形成的重要物质基础.
