利用卫星遥感资料对南海北部陆架海洋表层温度锋的分析

利用7年(1993～1999)月平均的SST卫星遥感资料，分析了南海北部陆架区域海洋表层温度锋在一年中的逐月变化特征，表明南海北部陆架海洋表层温度锋存在明显的季节内变化。结合风场的卫星遥感资料，分析了东北季风对南海北部陆架温度锋的影响，表明东北季风风速的增加有利于温度锋强度的增强。通过对黑潮南海流套入侵较强的1999年2月与流套入侵较弱的1998年2月的SST卫星遥感资料的对比分析，考察了黑潮南海流套的入侵对南海北部陆架温度锋的影响，结果表明黑潮流套的较强入侵能够增加陆架温度锋的强度，对温度锋的走向也会产生一定的影响。

A thermal centroid or a mass centroid?

This study reveals the physical backgrounds of the geometric centroid and the thermal centroid of the Western Pacific Warm Pool (WPWP) and points out their differences. The geometric centroid (actually a very close approximation to the mass centroid) anomaly of the surface WPWP correlates more closely with the Niño-3 region sea surface temperature anomaly (Niño-3 SSTA, an important indicator of El Niño/La Niña events) than the surface thermal centroid. Taking the WPWP depth (or heat storage) into account, the “real” mass or thermal centroid of the WPWP might correlate better with the El Niño/Southern Oscillation (ENSO) signals.     

Geodynamic Evolution of the Eastern Segment of the Azores-Gibraltar Zone: The Gorringe Bank and the Gulf of Cadiz Region

Detailed structural interpretation of the recently acquired deep seismic multichannel profiles along the Iberian Atlantic Margins (IAM Project) provides new results on the geodynamic evolution of the eastern part of the Azores-Gibraltar plate boundary. Thrusting and folding of the oceanic basement and of Mesozoic and Cenozoic sedimentary cover of the Gorringe Bank region are consistent with the N–S convergence of Iberia and Africa. Compressive structures in the Gorringe Bank region are spread over a wide area. Deformation under compression took place mainly in Tertiary times, as is evidenced by a basal unconformity and several discontinuities in Tertiary sediments, although some deformation has also been recorded in Quaternary sediments. The compressive structures in the Gulf of Cadiz are E–W oriented thrusts, folds and related diapiric structures. N–S oriented transpressive deformation is likely to occur in the western Portuguese platform. There is no continuity of structures from the oceanic to the continental domain, suggesting that deformation transfers from one side to the other through a transcurrent fault zone. The fault contact between the two domains is located in the ocean-continent transition zone.     

台湾岛及其邻域地层和构造特征

台湾碰撞造山带作为世界上最年青的造山带之一，具有其独特的地质环境。它位于菲律宾海板块和亚欧板块的交汇处，东北面为东北-近东西走向的琉球沟-弧-盆系，东侧为西北向运动的菲律宾海板块，向南为近南北走向的吕宋岛弧，并与冲绳海槽和马尼拉海沟的形成演化密切相关，从而造就了众多形态复杂、成因各异的区域地层和构造现象。台湾岛自东向西可划分为海岸山脉带、台东纵谷、中央山脉、西部山麓带和沿海平原带五个构造-沉积单元。以台东纵谷为界，两侧在地形地貌、地层组成、岩石性质、重力、磁力等地质地球物理特征上均表现为明显不同，分别隶属于不同的板块构造单元，西侧属于欧亚板块的中国大陆边缘，东侧的海岸山脉带则是北吕宋火山岛弧的向北延伸。     

南海陆坡天然气水合物成藏的构造环境

南海是西太平洋最大的边缘海之一，其复杂的构造演化，形成了构造特征迥异的南海陆缘，有利于天然气水合物的发育，南海地区在中中新统以上发育了上中新统，上新统和第四系3套地层，3套地层所对应的地质时期的沉降速率在纵横向上的差别均较为悬殊，总体而言，南海第四纪整体沉降速率较大，为天然气水合物压力场环境的形成提供了有利条件，南海复杂的构造背景形成了丰富多彩的构造地质体，特定的构造地质体与水合物形成关系密切，这里讨论了滑塌体、泥底辟、增生楔等构造地质体在南海的分布情况，分析了上述构造体与气体水合物地震标志BSR之间的关系，以及特殊构造带在南海的展布规律，提出了特殊的造带中天然气水合物的成藏模式。     

Optical interferometric observations of a transient event of 1986 March 13 in the coma of Comet Halley

During the recent apparition of Comet Halley in 1985-86 a transient ionic event in the form of a blob of H₂ O⁺ emission was recorded in thecoma at ～ 0^h UT on 1986 March 13. Observations were carried out using a special IHW filter for H₂ O⁺ emission at 7000 å/175 å, a 35 cm telescope, a Fabry-Perot interferometer and an image intensifier camera from Gurushikhar, Mt Abu. (24?39’N,72? 47’E). A Fabry-Perot inter-ferogram in Ha taken a few minutes later at the same location reveals strong hydrogen emission (Hα) associated with the blob. The velocity field in the blob is structured with relative velocities upto ～ 35km s^?1. The event is interpreted as arising due to the sector boundary crossing of the interplanetary magnetic field by the comet     

煤炭资源勘查误差理论研究

对煤炭资源勘查资源量与客观物质量之间差值的误差理论探讨,提出误差由真值误差、系统误差和离差3个基本部分组成,其中真值误差是不可消除的观测误差、系统误差是控制网度所决定的准确度标准、而离差是由地质构造及矿床形态的多解性产生的资源量波动。在此基础上,构筑了一个关于误差的数学模型,最后应用误差理论对现行勘查工作中常见的错误进行分析,并就如何避免错误及减少误差提出了见解。     

四川汶川大地震的构造分析

2008年5月12日在汶川映秀(北纬31.0°,东经103.4°)发生8级大地震,而后发生万余次余震,其最大震级为6.4级.此次地震属主震-余震型地震.通过构造分析认为.汶川大地震是构造地震,主要受龙门山断裂带的强烈活动控制.它是一种板内地震,其动力来源来自印度板块与欧亚板块的碰撞.而成都平原处于稳定地块中,尽管离震中较近,然受地震的影响有限,是比较安全的.
