Development and Application of Stress Transfer Modelling for Area Selection in Mesothermal Gold Systems

应力传递模型在中间金矿系统选区中的发展和应用许多中型金矿系统都是由低位移断层和剪切带控制的，这些断层和剪切带与高位移、地壳规模的断层和剪切带相邻。类比现代，孕震断层系统，金托管结构被解释为余震阵列，其形成是有关的应力重新分配和流体流动后，大位移断层上的主要滑动事件。该项目将测试和开发目前用于余震风险评估的库仑应力转移建模技术，以预测地壳规模剪切系统周围低位移、含金结构的分布。该技术有望为与断层有关的后生成矿系统的选区提供有力的辅助工具。

Development and Application of Stress Transfer Modelling for Area Selection in Mesothermal Gold Systems. Many mesothermal gold systems are hosted by low displacement faults and shear zones which develop adjacent to high displacement, crustal-scale faults and shear zones. By analogy with modern, seismogenic fault systems, the gold-hosting structures are interpreted as aftershock arrays whose formation is related to stress redistribution and fluid flow after major slip events on high displacement faults. This project will test and develop Coulomb stress transfer modelling techniques, currently used for aftershock risk assessment, for predicting the distribution of low displacment, gold-hosting structures around crustal-scale shear systems. The technique is expected to provide a powerful tool to assist area selection in fault-related epigenetic ore systems.
