| 摘 要： | 地壳流体在主岩溶解和迁移过程中，以搬运和交换物质、传输和释放能量的基本作用广泛影响地壳内部的造山、变质、成岩、成矿等地质作用和过程。流体的地质作用具有岩石圈动力学和大陆动力学的意义，是地球科学跨世纪的重大进展之一。文章从三个方面概述欧共体国家在近十年来对地壳流体研究的概况和进展：（１）７０年代始意大利托斯卡纳地热田的开发和利用对新生代—现代地热田热水系统近地表的超热地壳流体的研究成果；（２）８０年代欧共体国家开展的跨国多学科重大基础研究项目“欧洲地壳剖面综合地质调查”对欧洲中部华力西带结晶基底和中—新生代沉积盖层古地壳流体的研究成果；（３）９０年代联邦德国大陆超深钻现代和古地壳流体的研究成果。

| Abstract: | The crustal fluids play an important part in geological processes of orogenesis, metamorphism, diagenesis and mineralization during dissolution and migration of fluids in host rocks where it can transfer and exchange material as well as transmit and deliver energy. The geological activity of crustal fluids is important for the lithosperic and continental geodynamics. Its investigation leads to remarkable advances of the geosciences over the end of twentieth century. In this introductory paper, the author tries to give brief account about the basic facts and advances on the studies of crustal fluids in countries of the European Union as follows: (1) Geothermal fluid in geothermal field in Tuscany, Italy; (2) Paleofluid in Variscan basement and Mesozoic Cenozoic sedimentary cover in central Europe; (3) Recent and paleofluid in continental deep drilling (KTB), Germany. |
