摘要
未文通过哀牢山北段金矿带成矿期构造应力场与成矿流体(地下水)运移关系的研究发现,最大主应力低值区和已知金矿床、金矿点具有良好的对应关系,它们是成矿流体运移、卸荷的有利场所;成矿流体的运移受构造应力、温度梯度和水力梯度的联合控制。研究构造应力场与地下水运移、分布的关系不仅可以用于成矿预测,而且对于在新构造活动区寻找地下水、地下热水具有重要意义。
After studying the relationship between the tectonic stress field in mineralization epoch of Au deposit zone in the North of Ailaoshan and the movement of mineralization fluid (groundwater), the authors discovered that the low value districts of Max. principal stress are corresponding to the Au deposits and Au mineral occurrences which we have known. The movement of mineralization fluid is jointly controlled by tectonic stress,temperature gradient and hydraulic gradient. The study of the relationship between tectonic stress field and the moving and distributing of groundwater may not only be used in the forecasting of mineralization. but also is of great significance in looking for groundwater and ground hot-water in new tectonic active areas.
