2011~2020中国应用地球化学研究进展与展望

Research Progress of Applied Geochemistry during the Decade of 2011 to 2020 in China

在分析应用地球化学发展历程的基础上总结了应用地球化学的研究内容,着重介绍了勘查地球化学在调查、评价、开发和修复四个阶段近十年的研究进展。调查方法可分为传统化探和非传统化探方法,传统化探方法日趋成熟、规范并得以持续推广应用,非传统化探方法在覆盖区勘查备受重视;评价主要集中在确定元素组合、圈定异常和评价异常方面,除持续应用外,其方法技术仍以对比为主导,但知识驱动技术初露端倪;在开发方面则主要体现在地浸法铀矿采选方面;修复主要是针对矿山环境的修复,由此产生了地球化学工程学这一新兴领域。

The research progresses of applied geochemistry during the last decade in China are summarized in this paper.On the basis of the development history of applied geochemistry,the research contents are depicted,especially in the field of geochemical exploration.The research progresses of geochemistry exploration during the past decade in China can be summaried from four aspects,e.g.survey,assessment,exploitation and remediation.Traditional and non-traditional geochemical prospectings are devided according to their survey techniques,on the one hand,the traditional geochemical prospecting techniques are maturing and standarding and their applications are widening and progressing,on the another hand,the non-traditional geochemical prospecting plays an important and irreplaceable role in overburdened areas.In the aspect of the assessment,its main topics are concentrated on element association,anomaly determination and anomaly evaluation,and its applications keep progressing and widening;the comparison method is the dominated technique of the assessment,nevertheless,methods driven by geochemical knowledge become more and more important.In the aspect of the exploitation,its progresses reflect mainly on in-situ leaching techniques of mining sandstone hosted uranium deposits.In the aspect of the remediation,its progresses are mainly on the environment remediation of mines,which have formed a new research field of geochemical engineering.
