摘要
地壳中的流体及其作用问题,近年来正在成为地球科学研究的新热点与焦点。文章简要介绍了地壳中流体的基本概念与主要特性及其在全球构造、板块构造、区域构造与显微构造活动中的作用;着重介绍了流体在震源过程中的作用,地壳浅部热流体的循环与地震活动,地壳深部高导层与强震分布,断裂带中的水岩相互作用与断裂阀模式及地震水力学等。
During the recent years, the problem of fluids in the earth crust and its role has become a topic of general interest and focus in researches of the earth sciences. This paper gives brief introductions about the basic concept and main characteristics of the fluids in the earth crust and their role in the processes of the global tectonics, plate tectonics, regional tectonics and microscopic tectonics; emphati- cally introduces the role of the fluids in the earthquake hypocenter process, circulations of hot fluids in the shallower crust and earthquake activities, the high conductivity layer of deep crust and distribution of strong earthquakes; water-rock interreaction in the fault zones and the fault-valve model, as well as seismo-hydraulics.
