摘要
构造应力是地下水运移、分布的重要控制因素.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,最大主压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、成矿元素卸荷的有利场所;成矿流体的运移经三种因素联合控制,构造应力控制了其平面分布,流体上升的驱动力主要为温度梯度,其次为水力梯度.构造应力场与地下水运移、分布的关系研究不仅可以用于成矿理论研究、成矿预测,而且对于在新构造活动区寻找地下水、地下热水及矿泉水具有重要指导意义.
Tectonic stress is one of the important dominant factors of groundwater movement and distribution. On the basis of the study on the relationship between the tectonic stress field and the movement of mineralization fluid (groundwater) in mineralizing period of gold mineralization zone in the north of Ailaoshan,it is discovered that the low value districts of maximum principal stress are corresponding to the known gold deposits and gold mineralization and are the advantageous places for minerolizing fluid morement and mintralization solution unloading. The movement of mineralization fluid is jointly controlled by three factors among which tectonic stress controls the distribution on plane and driving power of the fluid going up comes mainly from tomperature gradient and bydraulic gradieut Secondly. The study on the relation between tectonic stress field and groundwater movement,distribution may not only be used in the study of mintralization theories and minerogenetic proganosis,but also is of guiding significance to looking for groundwater,ground hot -water and mineral water.
