摘　　要：中低温锡矿作为重要的矿产资源,其形成过程复杂且受多种因素影响。本文聚焦于中低温锡矿的形成过程,采用多场耦合数值模拟方法进行深入探究。通过收集大量与中低温锡矿形成相关的地质、地球化学、金属离子平衡浓度等数据,建立涵盖温度场、压力场等多场耦合的TOUGHREACT成矿化学反应浓度变化数值模拟计算模型,并深入分析了温度和压力的变化对含矿热液中锡离子的化学物质的相互作用和运移。通过多场耦合数值模拟为中低温锡矿的形成机制提供了新的认识,为深部隐伏矿体的探索和研究提供了科学依据。This study focuses on the formation process of medium and low temperature tin ore,and adopts multifield coupling numerical simulation method to investigate further.As an important mineral resource,the formation process of medium and low temperature tin ore is complicated and affected by many factors.By collecting a large number of geological,geochemical and metal ion equilibrium concentration data related to the formation of medium and low temperature tin ore ore,a numerical simulation model of chemical reaction concentration change of TOUGHREACT was established,which covers temperature field and pressure field.The interaction and migration of tin ions in mineralbearing hydrothermal solution under temperature and pressure were analyzed.The multi-field coupling numerical simulation provides a new understanding of the formation mechanism of medium and low temperature tin ore,and provides a scientific basis for the exploration and research of deep concealed ore bodies.
