流体地质作用与资源环境效应--基于第八届流体地球科学与矿产资源及环境灾害学术研讨会的综述

Fluid Geological Process and Resource Environment Effect-Summary of the 8th Symposium on Fluid Geoscience,Mineral Resources and Environmental Disasters

基于第八届流体地球科学与矿产资源及环境灾害学术研讨会的主要交流成果,从侧面综述了近几年地质流体的形成演化与矿产资源的富集分布及环境灾害研究进展和发展趋势。从深部地质作用与矿产资源,地质流体研究的物理化学技术,流体地球化学特征与地震活动,地热资源的赋存特征和发展现状,地质资源的成藏特征、主控因素以及富集规律,流体地球科学与地理自然环境等6个方面对本次学术研讨会主要交流成果进行了总结。结果表明:①油气和矿产资源的生成和演化机制、富集和运移机制以及勘探和开发技术的发展依然是目前流体地球科学领域研究的重点,且研究内容也更加注重资源产生和演化的历史与机制;②利用多样化且更精确的新技术对地质条件更加复杂、埋藏更深及勘探和开采难度更大的新领域进行拓展研究是当前的主要趋势;③目前中国极端自然灾害风险的不确定性受全球气候变化等自然、经济、社会因素的影响,表现出增长趋势,破坏性地震正处于频发时期,自然灾害的突发性、异常性和复杂性同时也表现出增长趋势,因此,提升中国自然灾害防治能力刻不容缓。

The 8th symposium on fluid geoscience,mineral resources and environmental disasters reflects the formation and evolution of geological fluids,the enrichment and distribution of mineral resources,and the research progress and development trend of environmental disasters in recent years.The relevant papers of the 8th symposium regarding fluid geoscience,mineral resources and environmental disasters from 6 aspects,including the deep geological processes and mineral resources,the physicochemical techniques of geological fluid research,the fluid geochemical characteristics and seismicity,the occurrence characteristics and development status of geothermal resources,the accumulation characteristics,controlling factors and enrichment rules of geological resources,the fluid geoscience and geographical natural environment,were summarized.The results show that①the generation and evolution mechanism,enrichment and migration mechanism of oil,gas and mineral resources,and the development of exploration and development technology are still the focus of the current research in the field of fluid geoscience,and the research content also pays more attention to the history and mechanism of resource generation and evolution;②it is the current main trend to adopt diversified and more accurate new technologies to explore new fields with more complicated geological conditions,deeper burial and more difficult exploration and exploitation;③at present,the uncertainty of China s extreme natural disaster risk is affected by many natural,economic and social factors,and it shows an increasing trend;destructive earthquakes are in a period of frequent occurrence,and the sudden,abnormal and complex characteristics of natural disasters are also showing an increasing trend,therefore,it is urgent to improve China s natural disaster prevention and control capacity.
