Computer simulations of coupled problems in geological and geochemical systems

摘要

The finite element method is used to simulate coupled coupled problems, which describe the related physical and chemical processe of ore body formation and mineralization, in geological and geochemical systems. The main purpose of this paper is to illustrate some simulation results for different types of modeling problems in pore-fluid saturated rock masses. The aims of the simulation results presented in this paper are:(1) getting a better understanding of the processes and mechanisms of ore body formation and mineralization in the upper crust of the Earth; (2) demonstrating the usefulness and applicability of the finite element method in dealing with a wide range of coupled problems in geological and geochemical systems, (3) qualitatively establishing a set of showcase problems, against which any numerical method and computer package can be reasonably validated.
