【摘要】 热液矿床成矿作用动力学过程涉及多时空高度耦合的物理和化学过程。数值模拟是研究这一复杂动力学过程的重要而有效的工具之一,也可在找矿预测等方面发挥重要作用。以南岭地区石英脉钨矿床为例,利用计算机求解控制构造-流体的物理和化学方程,定量揭示成矿热液聚焦流动与"五层楼"成矿的对应关系,正演高压成矿流体致使围岩发生水力破裂及其成矿效应。模拟结果与石英脉型钨矿床的构造地球化学特征相符。更多还原

【Abstract】 The dynamic process of hydrothermal ore-forming involves highly coupled physical and chemical processes at different spatial and temporal scales. Numerical simulation is one of important and effective tools to decipher these complex processes and aids in prospecting. The vein-type tungsten deposits in the Nanling Range are taken examples to show how to solve the physical and chemical equations controlling the coupled structure-fluids using numerical simulation,decipher the relationships between fluid focusing and the tungsten mineralization in the five-floor vertically morphological zonation quantitatively,and reproduce the influences of hydraulic fracturing driven by high-pressure fluids on wolframite precipitation. The numerical results are consistent with the geochemical characteristics constrained by previous studies.更多还原
