  sediments
Remanence magnetic records of the recent 130 000 years from the sediments in Nansha area, South China Sea
      
Two hundred and eighty-one samples, collected from drilling core NS93-5 located in the Nansha area of the South China Sea, were used to study the magnetic characteristics of the sediments in the sea.
      
Detailed rock magnetic results show that the magnetic minerals of the sediments were dominated by ferrimagnetic minerals such as magnetite, and a small contribution of hematite and maghematite also existed.
      
The sediments recorded three negative values of remanence magnetic inclination at the depth: 191-206 cm, 232-248 cm, and 292-308 cm.
      
may be the record of a Blake event in the sediments of the Nansha area.

The Yangtze delta, a large complicated delta system, has an area of about 51800 km2, of which the subaqueous area amounts to 29000 km~2. The delta is fed by Yangtze River which extents inland for more than 6300 km and has an annual sediment discharge of 486 million tons. At the mouth of the river, the average tide range is 2.25 m. and the tide currents play an importent role in delta formation. Combined analyses of 700 submarine surface samples and more than 500 cores have led to the follow conclusions:...

The Yangtze delta, a large complicated delta system, has an area of about 51800 km2, of which the subaqueous area amounts to 29000 km~2. The delta is fed by Yangtze River which extents inland for more than 6300 km and has an annual sediment discharge of 486 million tons. At the mouth of the river, the average tide range is 2.25 m. and the tide currents play an importent role in delta formation. Combined analyses of 700 submarine surface samples and more than 500 cores have led to the follow conclusions: 1. Yangtze delta consists of the delta proper, and associated depositional systems which include large sand bar in Chien-Tang Estuary, offshore tidel radiate sand bars near Jiang-Gang, and strand plain along both southern and northern flanks of delta. 2. In terms of hydrodanamical setting, sedimental characteristics and palaeomicrofauna assemblage, the delta can be classified into delta plain facies, delta front facies and prodelta facies, and each of which may further be divided into subfacies. About 11 distinct subfacies are presented in Yangtze delta system (see fiqure 7). 3. The deltaic facies sequence observed in descending order from the numerous cores at the river mouth bars and on delta plain correspond well with lateral occurrance of deltaic depositional facies from land toward sea.

长江三角洲是巨大的潮汐型三角洲,依据水动力作用,沉积特征和生物组合,三角洲主体可划分为三角洲平原相,三角洲前缘相和前三角洲相。三角洲的伴生沉积体系在海区有(?)港幅射砂洲和钱塘江砂坎,陆上为长江南北两侧的滨海平原。各相带又进一步划分出亚相,共有十一种亚相。钻孔揭示,三角洲自上而下的垂直相序与自陆向海沉积相依次出现的顺序基本一致.

The Luwaitou fringing reefs are one of the well developed reef areas in Hainam lsland. it is an elevated reef. There are two categories of sediments in reef region: coral reef and biodetritus. Physiographic-lily, it could be divided into five fades zones: the reel front, growing reef, reef flat, beach and lagoon; and each zone could be further subdivided. It is realized that, lithological character, grain size component, ccuiposition of sediment and biota (especially microfanna), are the useful diagnostic...

The Luwaitou fringing reefs are one of the well developed reef areas in Hainam lsland. it is an elevated reef. There are two categories of sediments in reef region: coral reef and biodetritus. Physiographic-lily, it could be divided into five fades zones: the reel front, growing reef, reef flat, beach and lagoon; and each zone could be further subdivided. It is realized that, lithological character, grain size component, ccuiposition of sediment and biota (especially microfanna), are the useful diagnostic criteria in discrimination of various reef facies.

鹿回头珊瑚岸礁是海南岛岸礁发育较好的地区之一,属于上升礁范畴。礁区沉积分为岸礁沉积和生物碎屑沉积两类。鹿区可划分为五个沉积相带:礁前带、礁沐生专带、礁坪带、海岸带和礁后泻湖带.各带按沉积特征还可细分为2—3个亚带。研究证明:沉积物粒度资料、物质组分和生物(特别是微体生物)的生态条件等可用作指相标志。

Foraminifera and ostracods were identified from more then 400 bottom samples taken from the East China Sea. As shown by the results of the qualitative and quantitative micropaleontological analyses, the basic factor controlling the distribution of the foraminiferal and ostracod assemblages is water depth and offshore distance, although water temperature, currents and salinity have strong influence on their distribution. These general distribution patterns have been complicated by occurences of Late Pleistocene...

Foraminifera and ostracods were identified from more then 400 bottom samples taken from the East China Sea. As shown by the results of the qualitative and quantitative micropaleontological analyses, the basic factor controlling the distribution of the foraminiferal and ostracod assemblages is water depth and offshore distance, although water temperature, currents and salinity have strong influence on their distribution. These general distribution patterns have been complicated by occurences of Late Pleistocene relict fauna. Six benthic foraminiferal assemblages, each representative of increasing water depth and salinity, were recognized from estuaries to Ryukyu trench: 1. Ammonia convexidorsa-Epistominella naraensis assemblage-estuaries: 2. Ammonia beccarii var.-Elphidium advenum assemblage-water depth<55m.; 3. Bolivina cochei-Ammonia compressiuscula assemblage-50-100m.; 4. Textularia pseudocarinata-Cibicides margaritifera assemblage-100-150m.; 5. Cassidulima spp. assemblage-150-700m.; 6. Lagena spp. assemblage-700-2000m.; Accordingly, G ostracod assemblages may be distinguished as follows: 1. Albileberis sinensis assemblage-estuaries; 2. Leguminocytkereis hodgii assemblage;-<50m.; 3. Munseyella-Cytheropteron assemblage-50100m.; 4. Bairdia-Cytherelloidea assemblage-100-150m.; 5. Krithe producta assemblage-150-2000m.. There are two groups of planktonic foraminiferal species occuring in the East China Sea bottom sediments: eurythermal species such as Globigerina bulloides, Globigerina iuiniueloba and G. pumilio, and warm water species such as Orbulina universa, Globoroialia menardii. The warm water planktonic foraminifera are absent in region with water depth less than 50m., but are partly present in 50-100m. depth region and abundant beyond the 100m. isobath, thus indicating the infuence of the Kuroshio warm water current. The test size of planktonic foraminifera, the ratio of planktonic specimens to total foraminiferal mumber, as well as the ratio of ostracod to foraminiferal number increase generally with distances from coastline to trench.
