摘    要:目前国内外对构造应力作用下地球内部流体运动的规律与特征的研究已经很多 ,但面向地应变固体潮对地壳微裂缝系统的微渗漏作用影响的研究尚属空白。地球在太阳、月球的引力作用下 ,一方面在其表面的海洋、湖泊形成直观的潮汐现象 ;另一方面固体地球自身还形成肉眼无法看到的粘弹性形变 ,称为固体潮。固体潮不仅能引起重力变化、地面倾斜和地面伸缩等地球物理现象 ,而且还为地壳内微裂缝系统提供了永恒的、周期性的伸缩开合变化的动力 ,大大提高了流体在微裂缝系统中微渗漏的规模和距离 ,造成流体中物质元素的迁移和变化的地球化学现象。文中主要阐明了地壳裂缝系统和流体微渗漏作用的客观存在 ,探讨并总结了地应变固体潮对微裂缝系统的应力作用特点以及为流体微渗漏作用所作出的重要动力贡献 ,并将固体潮与地球化学有机联系在一起 ,从理论上说明流体携带包含深部矿藏 (体 )信息的特征元素或物质完全有可能通过微渗漏作用迁移至地表并形成该元素或物质的地球化学异常 ,为当前的地表土壤法、地气法、电提取法、电吸附、吸附丝等多种地球化学找矿方法提供可信的理论依据。

关 键 词:地应变  固体潮  地球化学探查  微裂缝  微渗漏

Abstract:Many research works have been done on the moving characteristics of ground-fluid controlled by structural stress in China and abroad , but the research on microseepage of microcrack caused by Earth tide is complete blank . Under the universal gravitation of the sun and moon, the tides of ocean and lake in the Earth are formed , and the micro-glutinous-elastic deformation of the Earth (called as Earth tide) that could not be distinguished by our eyes is caused .The Earth tide would not only cause some phenomenon of geophysics such as the change of gravity , the aslope of ground and the flex of ground , but also supply the perpetual cyclical power for the ground microcrack system being opened and closed. It would greatly increase the intensity and distance for microseepage of fluid in the microcrack and bring about the migration and redistribution of elements . The main goals of this article are to show that the Earth's microcrack and microseepage is the objective existence, to search and summarize the characteristics of the Earth tide related to the strain of microcrack system and the important power role of microseepage given by earth tides,to combine the Earth tide with geochemistry, to verify in theory that the special elements or components which contain the information of deeply buried ore of deposit can be migrated to surface by microseepage to form geochemical anomalies , and to lay a reliable and scientific theoretical groundwork for many geochemical prospecting techniques such as earth soil survey, earth gas survey , electrical extract survey ,electrical absorption survey and absorbed thread survey , etc.
Keywords:earth strain  Earth tide  geochemical prospecting  microcrack  microseepage
