Based on the different geomorphic units in Wuhan area and the fifteen groups of drill-core samples having two thousand grains of quartz sand in total, this paper makes the identification of scanning electron microscopy in morphology and the combined analyses of x-ray energy spectra elements in accordance with each group.It is demonstraed that deposits of this area from Neogene period to Holocene epoch in Quaternary period is products of near-by source materials belonging to repeatedly sedimentary environment in stages at time-spatal distributions. i. e. quartz sand separating itself from wother rock-subagueous environment on continent characterized by rivernet alternating-weathering and diagenesis. This paper also desribes that aftef depositing at continent-subagueous environment, the particular geomorphic unit of Qing shan is once again subjected to a violent wind adrasion.

The information on benthic organisms and the geochemical environment obtained from the Chinese First Exploration on Antarctic Ocean and its succeeded analytic works.The results shows that in the circumstances of the studied area in which the bottom water is plentiful in dissolved oxygen and the surface sediments is in weak oxidation(manganese oxides as dominated oxident) ,benthic organisms grow well while the prosperity of the animals are limited below5-1 0 cm of the profiles in which the environment is controlled by sulfate reducing reaction. It is the result of evolution for the characteristics of the main benthic organisms under the special circumstance in studied area.On the condition of low temperature of the Antarctic Ocean,the solubility of carbonates is higher than that in otherocean's,but the concentration of calcium in overlying water and porewater is not higher than that in other ocean,which may results in the difficulty forthe crustacean and molluscs to obtain sufficient calcium to form their solid crust.Furthermore,there is a certain relation between the amount of sedentary polychaetes and the temperature in overlying waters. That might demonstrate that the animals had still not quite adjusted to the extremly cool of the Antarctic Ocean,however it should be left for furtherwork.Besides,the research proposed thatthe number of the microorganisms is controlled by the amountof active organic matters in the sediments.

本文分析了中国首次南大洋考察 (1 984/1 985 )现场及后续工作资料 ,并与其它纬度有关海区进行了比较。结果表明 ,在研究海湾充氧的底层水及弱氧化性的表层沉积物环境 (锰氧化物为优势氧化剂 )中 ,底栖生物较为丰富 ;而在垂直深度 5 - 1 0 cm以下 ,硫酸盐还原反应遏制了底内多毛类动物等的向下繁衍。测区主要大型底栖动物的分布特点是在特定条件下演化的结果 ,南大洋气候寒冷 ,碳酸盐溶解度较高 ,但其沉积物上覆水和间隙水中钙离子却并不高于其它纬度海区 ,因此钙离子的不足可能限制了需要钙质碳酸盐形成外壳的甲壳类和软体动物的繁衍而造成其在研究区域壳薄且所占比例较少的分布特征。上覆水温与底栖多毛类的生长有一定的关系 ,这可能表明南大洋测区该类生物尚未完全适应极区的寒冷气候。沉积物中微生物的数量主要受活性有机质量的制约。

The relationship between the contents for Cu, Pb, Zn, Cd, Fe and Mn in the surface sediments of oxygen-deficient waters of the Zhujiang estuary was analyzed statisti-cally. Their characteristics of interaction in the processes of transport and sold-liquid equilibrium, and the influence of the environmental factors and major compositions of sediment on the deposition-solution process of the surface sediments, as well as the enrichment effect of the surface sediment to the metals were discussed. The result showed that the enrichment factors (K) of the sediment to Cu, Pb, Zn and Cd are arranged in the order of Kc.d>Kpb>Kcu>Kzn, where Kcd value is higher than the ones of the reference area and the Changjiang estuary. This revealed that in the surface sediments of the waters there might be authigenic sediments of CdS, and also no obvious change in geochemical characteristics of the trace metals.

研究了珠江口贫氧区表层沉积物中Cu,Pb,Zn,Cd,Fe和Mn含量的相互关系;探讨它们在迁移和固-液平衡过程相互作用的特征;研究了沉积物的环境因素和重要组分对其沉积-溶解作用的影响;研究了表层沉积物对它们的富集作用。结果发现,沉积物对Cu,Pb,Zn和Cd的富集系数(K)排列次序为K_(Cd)>K_(Pb)>K_(Cu)>K_(Zn)。K_(Cd)大于对照区和长江口的相应值。此结果说明,上述区域的表层沉积物中可能有自生的CdS。且贫氧水的表层沉积物中Fe,Mn,Cu,Pb和Cd的地球化学特性尚未有显著的改变。
