青岛地区北北西向断裂及其地质意义

通过地下水，温泉地热水开发的实践验证和野外观察发现，青岛及邻区ＮＮＷ向断裂具有张扭性质，具有良好的导水性，是本区重要的含水断裂，是寻找地下水源的重要标识，此外，该断裂在水文地质，工程地质，环境地质方面以及对中国东部海岸线方向均有控制作用，对该断裂的研究具有重要的意义。

THE NNW DIRECTION FAULTS IN QINGDAO AREA AND THEIR GEOLOGICAL SIGNIFICANCE

Based on observations, field studies and the test of practice in production, we found that the NNW direct faults appeared in the Qingdao area are a group of tension-shear faults as well as a group of water-rich faults. They are an obvious mark in searching for underground water and geothermal water. The NNW direction faults have apparent influences on the hydrogeology, engineering geology, environmental geology and the figure of the shoreline in this area. Therefore it is very important to study the NNW directi0n faults.
