Mineralization is commonly the result of full feedback coupling between the four processes of mechanical deformation,thermal transport,fluid flow,and mass transport.Numerical simulation,which sets up the coupled model to depict chemical and physical rule,is used to solve this complex problem.This paper introduce primary coupled models of ore-forming fluid:coupled deformation-fluid flow modeling,coupled deformation-thermal transport-fluid flow modeling,coupled thermal transport-fluid flow-mass transport modeling,coupled deformation-thermal transport-fluid flow-mass transport modeling.The result of these models are presented here to illustrate that gravity and thermal-gradient is the important mechanism for driving fluid flow;how the fluid flow is controlled by some structure;fluid is favored to the higher permeability fault and rocks.Therefore,various parameters(e.g.permeability) involved in mineralization are critical for predictive exploration.
