成矿过程弱信号提取的定性和定量相结合仿真法研究

The concept of nonlinear evolution and new methods of simulation of chaos dynamics are applied to puts forward the models of time variable Logistic map and combining qualitative with quantitative simulation for high precisely extraction of weak signal on mineralization overlapping process and are applied to stratigraphic correlation on sedimentation series ..The model of two -dimensional coupled map lattices of time variable and multiple-variable Logistic map are applied to simulation of chaos dynamics in three-dimension on hydrothermal sedimentation basin ,which has established the basis for dynamic modeling the palaeogeographic environment of basin and mineralization..
