调查区(东经115°—120°,北纬18°—24°)东北连台湾海峡,北部属大陆架,往南经大陆坡而降至海盆。海底表层沉积物中含有极其丰富的有孔虫壳体,其分布具有明显的规律性,本文对南海东北部海区的现代海洋沉积环境作初步探讨,这对识别古生态沉积环境及沉积作用具有重要意义。 The survey area (longitude 115 ° -120 ° longitude and latitude 18 ° -24 ° north latitude) connected the Taiwan Strait to the northeast with the continental shelf to the north and dropped to the south via the continental slope. The marine surface sediments contain extremely rich foraminifera shells, and their distribution has obvious regularity. This paper makes a preliminary study on the modern marine sedimentary environment in the northeastern South China Sea, which is important for identifying paleoenvironment and sedimentation significance.
