成矿过程水岩反应研究态势

水岩反应是矿床学的重要研究内容,亦是地球科学领域的前沿问题。复杂性理论、渗流力学等的引入和测试技术的提高,促使水岩反应研究向系统化和定量化的方向发展,并取得了诸多相关进展。通过水岩反应中元素迁移过程和机制的探索,可以进行流体示踪及推测相关水岩反应过程;定量计算、物理实验和数值模拟是水岩反应研究的主要手段;对复杂的水岩反应体系,应综合运用各种方法,以更加真实地重塑水岩反应的过程。

TREND OF STUDY ON WATER ROCK REACTION IN ORE-FORMING PROCESS

Water-rock reaction(WRR) is not only the significant research content of metallogeny,but also the frontier geoscience problem.Introduction of complexity theory,hydrodynamics and some other theories and the improvement of testing technology led to the WRR research developing in a systematical and quantitative direction and the relevant achievements.This paper focuses on the process and mechanism of element migration and isotope fractionation based on which geological data of elements and isotopes are used to tracing fluid activity and estimating the process of WRR.Quantitative calculation,numerical simulation and physical experiment are the main means of WRR study,and each method has its own characters.For the complexity of water-rock system,all the methods should be used to remolding the geological process of WRR.
