地球物理学中物理学应用的可喜进展

为庆祝爱因斯坦奇迹年100周年，联合国教科文组织（UNESCO）把2005年定为“世界物理年”。100年前爱因斯坦还是瑞士伯尔尼市专利局的一个小职员时，就已经发表了3篇足以永远改变物理学界的论文，包括：（1）提出狭义相对论并证明了质能方程（E=mc^2）；（2）用普朗克当时新提出的尚处于争论中的光子概念（E-bv）解释了光电效应；（3）运用当时还远不能为世人所接受的玻尔兹曼分子动力学（E=kT）研究了布朗运动的宏观现象。

The TRANSMED Atlas： geological-geophysical fabric of the Mediterranean region——Final report of the project

Geological research on the Mediterranean region is presently characterized by the transition from disciplinary to multidisciplinary research, as well as from national to international investigations. In order to synthesize and integrate the vast disciplinary and national datasets which are available, it is necessary to implement maximum interaction among geoscientists of different backgrounds. The creation of project-oriented task forces in universities and other research institutions, as well as the development of large international cooperation programs, is instrumental in pursuing such a multidisciplinary and supranational approach. The TRANSMED Atlas, an official publication of the 32nd International Geological Congress (Florence 2004), is the result of an international scientific cooperation program which brought together for over two years sixtythree structural geologists, geophysicists, marine geologists, petrologists, sedimentologists, stratigraphers, paleogeographers, and petroleum geologists coming from eighteen countries, and working for the petroleum industry, academia, and other institutions, both public and private. The TRANSMED Atlas provides an updated, synthetic, and coherent portrayal of the overall geological-geophysical structure of the Mediterranean domain and the surrounding areas. The initial stimulus for the Atlas came from the realization of the extremely heterogeneous nature of the existing geological-geophysical data about such domain. These data have been gathered by universities, oil companies, geological surveys and other institutions in several countries, often using different procedures and standards. In addition, much of these data are written in languages and published in outlets that are not readily accessible to the general international reader. By synthesizing and integrating a wealth of preexisting and new data derived from surficial geology, seismic sections at various scales, and mantle tomographies, the TRANSMED Atlas provides for the first time a coherent geological overview of the Mediterranean region and represents an ideal springboard for future studies.     

Delimitation of the Paranapanema Proterozoic block： A geophysical contribution

This study focuses on the basement structure of the Paraná Basin in South America, based on geological and geophysical data. It is a large intracratonic basin formed from the Late Ordovician until the Cretaceous,when a sequence of continentalflood basalts eruptions covered the entire basin, preceding the break-up of Western Gondwana. Isostatic modeling was applied to large gravity surveys comprising more than 12,000 gravity stations. The residual Bouguer anomaly pattern,representing the crustal contribution of the crystalline basement, as well as the sedimentary and volcanic layers of the basin, reveals similarities between the basement gravity signature and the exposed rock. The stress patterns of the Late Ordovician and Cretaceous tectonic events present a geographically coincident maximum,and the correlation between gravity highs and the main attenuation (beta factor) suggests the presence of some preexistent suture zones. The resultant mosaic of gravity blocks and the location of major faults give support to the presence of an important Proterozoic cratonic feature, here referred to as Paranapanema block.     

多道瞬变电磁法(MTEM)技术分析

多道瞬变电磁法(MTEM)具有深度大且探测精度高的特点,是目前电磁法领域研究热点之一。为推进多道瞬变电磁法深部探测系统的研发,对多道瞬变电磁法的技术特点及地球物理机制进行了分析。首先,对多道瞬变电磁法的关键技术进行总结,其特点包括:采用大功率接地源形式;编码发射;多道观测;类地震资料处理。然后,指出多道瞬变电磁法的地球物理实质:多道瞬变电磁法属于近源测深,即通过改变偏移距达到测深目的;接收信号包括系统响应和大地脉冲响应(即含有一次场与二次场的混合场)信号,采用反卷积方法获取大地脉冲响应。最后,针对中国复杂环境下的深部探测,对现有的多道瞬变电磁法提出改进思路:1把二维观测系统改进成三维观测系统,即三维数据采集系统,使其应用性更强且更方便,探测深度大,精度高;2把常规一维拟地震资料简单处理改进成三维拟地震成像解释;3从油气勘探领域拓展到复杂的深部矿产资源领域。
