Computational simulation of iron ore-forming processes in the Caiyuanzi siderite ore district, Guizhou, China

FEM‐based dual length‐scale simulation of hydrothermal ore‐forming systems involving convective flow in fluid‐saturated porous media

“…With the drive of finding new mineral resources in nature, computational simulation methods have been broadly used to simulate hydrothermal ore‐forming systems within the upper crust of the Earth 1–11 . From the scientific point of view, a hydrothermal ore‐forming system usually involves the following four main processes: a pore‐fluid flow process, a heat transfer process, a mass transport process and a chemical reaction process in the fluid‐saturated porous medium.…”

“…With the drive of finding new mineral resources in nature, computational simulation methods have been broadly used to simulate hydrothermal ore-forming systems within the upper crust of the Earth. [1][2][3][4][5][6][7][8][9][10][11] From the scientific point of view, a hydrothermal ore-forming system usually involves the following four main processes: a pore-fluid flow process, a heat transfer process, a mass transport process and a chemical reaction process in the fluid-saturated porous medium. This means that for the purpose of computationally simulating a hydrothermal ore-forming system, it is necessary to mathematically consider a nonlinearly coupled problem containing the abovementioned four main processes, 6,7 so as to derive mathematical governing equations of the coupled problem in the fluid-saturated porous medium.…”

Numerical Modeling of the Hydrothermal Metallogenic Mechanism Associated with the Ergu Pb-Zn Deposit, Heilongjiang, China: An Example of Pore-Fluid Convection Controlled Mineralization

“…(5) What was the post-cooling influence of the solidified magma and tectonic faults on the orebody distribution in the oreforming system? Obviously, these five fundamental questions involved in the formation of the Ergu Pb-Zn deposit need to be answered through considering the controlling dynamic processes and mechanisms in a strictly scientific manner [19][20][21][22][23][24][25][26][27][28][29].…”

“…Although the traditional geoscience method is commonly used to describe the observed mineralization phenomena, it cannot be used to explain, in a strictly scientific manner, how and why the observed ore deposits formed where they are located, because the controlling dynamic processes involved in the mineralization and orebody formation are not considered in the traditional geoscience method [19,30,31]. In order to address this fundamental issue, the computational simulation method, which is closely associated with the emerging computational geosciences, has been developed and used in recent years [19][20][21][22][23][24][25][26][27][28][29]31,32]. Compared with the traditional geoscience method, the specific characteristics of the computational simulation method include the following four aspects.…”

“…Fourth, advanced computational algorithms can be developed and used for solving the MGEs associated with the considered ore-forming system. Due to the aforementioned characteristics, computational simulation methods have been broadly used for solving many different types of problems in the field of geosciences [19][20][21][22][23][24][25][26][27][28][29][31][32][33]. Therefore, the computational simulation method is naturally chosen as a research tool in this study.…”
