摘要
基于青岛地区的工作经验,本文提出在花岗岩区找寻地下水源应着重注意的几个问题: (1)可用构造岩相学的新思路确定区域内的新构造断裂。 (2)只有在野外正确确认断裂构造是否于第三纪中期经过力学性质的转化,方可确定哪些断裂为开放系(含水)、哪些断裂为封闭系(不含水)。 (3)为提高出水的成功率,选择断裂的交汇点进行钻探尤为重要,而走向N20°W与走向N70°W二组断裂的交汇点为“异常交汇点”。文中还提出,上述三个问题对指导生产实践具一定的普遍性意义。
Based on working experience in Qingdao area some criterions in the survey of ground water at granite area are presented:(1) Wewly fault structure in the study area can be determined by the method of structural facies analysis.(2) It can be defined that which is the open system(containing water) and which is the close system(notcontaining water) can be distinguished only when we have correctly determined whether the mechanics nature of the fault has been transformed.(3) In order to raise the successful ratio, it is necessary to choose the site at the intersect point of faults with different trend and the intersect point of fault with strike N20°W and fault with strike N70°W is 'abnormal intersect point'.
