摘要
基于FLAC3D的流-固耦合模块,运用数值模拟方法,将金狮岭地区构造-流体-成矿系统及其动力学作为一个统一的整体进行了研究,根据模拟得到的主应力、最大主应力、最大剪应力、法向应力、主应变率、最大主应变率、最大剪切应变率和体积应变率等的定量结果,分析了矿床的成因和机制.模拟结果显示:主应力和主应变率大的区域,是成矿的有利部位,结合实际地质进行了相关验证.根据这些结论,最终圈定出金狮岭地区最具找矿潜力的四处区域.
On the basis of the fluid solid coupling module of FLAC3 D,using numerical simulation method,the structural-fluid-metallogenic system and its dynamics in the JinshiLing area are studied as a unified whole. Based on the quantitative results of principal stress,maximum principal stress,maximum shear stress,normal stress,principal strain rate,maximum principal strain rate,maximum shear strain rate and volumetric strain rate,the cause and mechanism of ore deposit formation are analyzed.The simulation results show that the region with large main stress and main strain rate is the favorable part of mineralization,and it has been verified in combination with the actual geology conditions.According to this conclusion,it finally found four regions with the most prospecting potential in Jinshiling area.
