摘要
地球内部地质过程及其相互作用不仅控制了全球地质格局的形成演化,也控制着地热资源的形成和地震活动的发生。本文通过系统调研及归纳总结,系统讨论地热资源与地震活动的共生深部驱动机制。首先,总结了全球高温地热带及大型/超大型地震带的形成背景,大多数高温地热与大型地震在空间分布上具有重合性,形成于活跃的板块边缘,而板内常形成中—低温地热且周缘伴随地震活动;其次,总结了地热资源及地震活动共生的深部驱动要素,发现流体及断裂构造在热能和地震的释放中起着至关重要的作用,是地热资源与地震活动深部主要的控制要素;再次,总结了地热资源与地震活动深部地球物理探测成果,表明大地电磁等方法可揭示地热与地震形成的同源关系与因果关系,地热与地震源于深部物质与能量的交换;最后,对地热资源与地震活动的共生深部驱动机制研究方法及发展方向进行了展望。
The geological processes and their interactions in the earth not only control the formation and evolution of global geological patterns,but also control the formation of geothermal resources and the occurrence of seismic activities.Through systematic investigation and summary,this paper systematically discusses the symbiotic deep driving mechanism of geothermal resources and seismic activities.Firstly,the background of the formation of global high-temperature geothermal and large/ultra-large seismic zones are summarized.Most high-temperature geothermal and large earthquakes overlap in spatial distribution and are formed at active plate margins,while medium-low-temperature geothermal is often formed in plates and accompanied by seismic activities.Secondly,the deep driving factors of the symbiosis between geothermal resources and seismic activity are summarized,and it is found that fluid and fault structure play a crucial role in the release of heat energy and earthquake,and are the main controlling factors of geothermal resources and seismic activity in deep depth.Thirdly,the results of deep geophysical exploration of geothermal resources and seismic activity are summarized,indicating that the homology and causality relationship between geothermal and earthquake can be revealed by magnetotelluric methods,and geothermal and earthquake are derived from the exchange of deep matter and energy.Finally,the research methods and development direction of the deep driving mechanism of the co-occurrence of geothermal resources and seismic activities are prospected.
