北黄海盆地区域地质特征

北黄海盆地位于黄海的北部，由于勘探程度低，研究投入少，使得它成为我国迄今为止尚未发现油气的惟一海区。随着我国在南黄海盆地和朝鲜在北黄海盆地东部发现油气，如何实现北黄海盆地油气突破，成为我们研究的焦点。结合该区现有资料和前人研究成果，对北黄海盆地的地球物理场和地质构造特征进行了全面的论述，并在此基础上，对该区油气资源远景作了初步评价。     

Comparison among four kinds of data of sea surface wind stress in the South China Sea

By using remote sensing (ERS) data, FSU data, COADS data and Hellerman & Rosen-stein objective analysis data to analyze the sea surface wind stress in the South China Sea, it is found that the remote sensing data have higher resolution and more reasonable values. Therefore we suggest that remote sensing data be chosen in the study of climatological features of sea surface wind stress and its seasonal variability in the South China Sea, especially in the study of small and middle scale eddies.     

Hydrothermal Metalliferous Sediments and Waters Off the Lesser Antilles

Considerable metal enrichments have been found in hydrothermal fluids and metalliferous sediments off the central Lesser Antilles Volcanic Arc. The elements variably enriched in the fluids as a result of the hydrothermal activity are Fe, Mn, As, Si, B, Li and in the sediments, Fe, P, Mo, As, Sb, Hg, Cu and Pb. Variations in the concentrations of these elements in both fluids and sediments along the arc result from a number of factors, the most important of which is the stage that each island's volcano has reached in its eruptive cycle. Although hydrothermal mineralization on the sea floor off the islands is only low grade, phase separation in the hydrothermal fluids at depth could be leading to higher grade stockwork mineralization below the vent fields or the discharge of metal rich brines on the lower flanks of the volcanic islands.

水成沉积与风成沉积及古土壤的磁组构特征

晚第四纪水成沉积、风成沉积、古土壤等的磁组构研究表明,不同成因的沉积物具有明显不同的磁组构特征。一般地,水成沉积的体积磁化率Ｋ受物源和水动力因素控制,Ｐ和Ｆ均＞１．０２,ｑ＜０．５;风成沉积的Ｋ受物源控制,内陆黄土的Ｋ明显高于沿海黄土及海岸风沙Ｋ,Ｐ和Ｆ均＜１．０２,ｑ的平均值＞０．５５;古土壤的Ｋ受母质沉积类型和成土环境的氧化还原条件控制,内陆古土壤的Ｋ偏高,沿海古土壤的Ｋ偏低,内陆古土壤的Ｋ远高于沿海古土壤的Ｋ,Ｐ和Ｆ均＜１．０２,ｑ的平均值在０．５左右。运用典型沉积的磁组构特征对比分析未知沉积物,可以得到未知沉积物的物源、沉积过程和环境信息。     

南澎列岛及邻近海域地质地貌与灾害地质分析

南澎列岛及邻近海域是广东沿海灾害地质因素较集中和类型较齐全的地区之一。根据野外调查资料，简要地分析了区内地质地貌以及活动断裂、地震活动、地面沉降、滑坡、地裂和沙土液化等基本特征和分布规律，同时还对区内地质灾害进行了初步分析。     

南沙群岛海区珊瑚礁灾害性地质分析

珊瑚礁是一种特殊的岩土介质，有独特的灾害地质类型。珊瑚礁灾害地质研究是现代工程地质学的一个新课题。通过珊瑚礁的地质记录研究了内动力灾害地质类型（包括活动断裂、地震和火山活动等）、外动力灾害地质类型（包括海底槽谷与地形突变带、崩塌、滑坡、峰礁与埋藏礁、泥丘、埋藏负地貌等），同时还分析了人类活动对珊瑚礁发育的影响。
