| 摘 要： | 柴达木盆地是我国极为重要的K、B、Li盐类资源富集区,承担着建设世界级盐湖产业基地的重任,却存在成矿规律不明确、可采卤水资源找矿效果不显著的瓶颈,盐湖资源面临着严重的可持续发展问题。本文强调将柴达木盆地盐湖作为一个地球化学系统进行探讨,重点梳理了盐湖元素富集机制的核心问题,集成分析了盐湖同位素地球化学所面临的机遇与挑战,并总结提出柴达木盆地盐湖K、B、Li成矿地球化学系统,以服务于盐湖成矿规律研究和资源勘查评价。盐湖成矿地球化学系统是指在地质单元和时空区域的多维系统内,控制成盐元素活化—迁移—富集—保存的多种地球化学过程子系统的总和,是各类地质动力条件、构造成矿要素、气候水文过程及所形成的矿床系列组合的有机整体,并十分注重地球化学在其中的应用。盐湖成矿地球化学系统的提出,可以在一定程度上对研究对象、研究技术方法体系和研究视角进行有效限定,属于盐湖矿床研究的一种思维方法,并有望为盐湖成矿规律研究提供一种科学范式。

| Abstract: | Qaidam Basin,a very important K,B and Li resources producing area in China,undertakes the task of building a world-class salt lake mining industrial base.However,its development have been hampered due to the bottleneck of unclear metallogenic regularity and poor prospecting effect of recoverable brine resources.In this study,we emphasized that salt lakes in the Qaidam Basin should be discussed as a system when conducting research on metallogenic laws.On the basis of sorting out the core issues of element enrichment mechanism and evaluating the opportunities and challenges of isotope geochemistry in salt lake,we proposed that the ore-forming geochemical system of K,B and Li resources in salt lake brine of Qaidam Basin can serve for the exploration and evaluation of salt lake resources.The geochemical system of salt lake mineralization is an organic whole that composed of geochemical processes and mineral deposit series combinations within a certain geological unit and spatio-temporal region,which controls the activation,migration,enrichment and preservation of salt-forming elements;and attaches great important to the application of geochemistry in its research.The proposed geochemical system of salt lake mineralization is a thinking method for the study of salt lake deposits,which can effectively define the research object,research technology,method system and research perspective to a certain extent,and expected to provide a scientific paradigm for the study of salt lake mineralization laws. |
