| 摘 要： | 高分辨率浅地层剖面资料显示,南黄海浅部大范围存在有埋藏古河道、埋藏古三角洲、埋藏古湖泊和埋藏古潮流沙脊等古地貌形态.根据声学反射特征可将这些埋藏古地貌进行识别,获得其类型、成因、分布、内部组成、外部形态及与周围地层接触关系等多方面较为详细的认识.同时,埋藏古地貌是一种海洋地质灾害现象,对海洋工程有着直接或者间接的影响.

| Abstract: | Data from high resolution shallow seismic profiles indicate that there occur various buried paleo-river channels,paleo-deltas,paleo-lakes and paleo-tidal sand ridges in a wide area of the South Yellow Sea.They are possible to be recognized with acoustic reflection methods.In this paper,we described the types of the buried geomorphological features,their morphology,internal structure and contact with surrounding geological bodies;defined their spatial distribution and discussed their origin.All the buried ge... |
