摘要:Taking the Jinchang gold-copper field in Yinan County, Shandong Province, China, as an example, the authors have proposed that the migration and concentration of ore-forming substances carried in the hydrothermal solutions might be mainly controlled by the structural deformation taking place during the mineralization epoch. It has been found that the ore-forming elements are generally concentrated in the places with strong structural deformation and that different types of ore bodies occur in different parts of deformational structures, In addition, the authors have conducted a quantitative evaluation of the structural control over the emplacement of ores through petromechanical experiments, measurement of physico-mechanical parameters of the rocks, inversion of the stress field and simulation of distribution of migration potential of the ore-forming solutions with the theory of infiltration mechanics.
