Optimization of hydrothermal alternation rate of olivine using exchange Monte Carlo method

Abstract

Hydrothermal experiments were carried out in olivine-quartz-H₂O system. By using unique tube-in-tube type hydrothermal experiments vessel, spatial and temporal data were obtained.
The observed mineral distribution was modeled by reaction-diffusion equation. To model our experiments, we set eight unknowns. However, this optimization problem on such many parameters would have several local minimums or broad minimum. Here, to overcome this problems, we use an optimization algorithm of the exchange Monte Carlo method rate law during serpentinization will be discussed.
