摘要
热液矿床的形成是一个复杂的多因素耦合过程,包括传热、流体运移以及物质的传输和沉淀。近年来,随着计算机技术和计算数学的发展,多过程耦合动力学数值模拟在成矿研究中的应用越来越深入,主要模拟成矿系统中的热传递、流体流动、构造变形和化学反应过程以及它们之间的相互作用。本文首先介绍了数值模拟的基本方法、常用的数值模拟软件及其应用范围,其次总结了多过程耦合动力学数值模拟在热液成矿理论研究和成矿预测中的应用,最后总结了数值模拟的优缺点并讨论其发展趋势。数值模拟是解决一些成矿问题的有效分析工具,将会推动矿床研究从定性、半定量往定量的方向转变。
Formation of hydrothermal deposit is a complex multi-coupled process,which involves heat transfer,fluid flow and solute transport.With the development of computer technology and computational mathematics,numerical simulation of dynamics on coupled multi-processes has been applied more and more widely in researches of mineralization in recent years,mainly simulating the thermal(T),hydraulic(H),mechanical(M)and chemical(C)processes in the mineralization system as well as their interactions.In this paper,we review the application of numerical simulation methods in the study of ore deposits,including(1)a brief introduction of general theories and the commonly used numerical simulation software;(2)the application of numerical simulation of dynamics on coupled multi-processes in the studies of the Mississippi Valley-type Pb-Zn,unconformity-related uranium,porphyry,skarn deposits and the metallogenetic prediction;and(3)a discussion of the significance and limitations of numerical simulation for the study of metallogenic processes and its future directions.Numerical simulation is an effective analytical tool to solve some complicated geological problems,which will promote the transformation of ore deposit research from qualitative and semi-quantitative to quantitative.
