摘要
根据野外地质观察和第四系的断错,在青岛即墨温泉盆地发现第四纪以来活断层。笔者在阐述了温泉盆地第四纪以来活断层的几何特征、构造特征的基础上,阐述了活断层产生的地质背景。用地震预测整体观的视角,认为盆地中第四纪以来活断层是与沧口—温泉活动断裂、温泉地热异常、地震异常、地球化学异常具有密切的成因联系。
Based on field geological observation and the preserved Quaternary offset, the authors discovered active faults since Quaternary in Jimo hot spring basin. This paper deals with geometry and structural characteristics of the active faults existent since Quaternary and geological setting for the formation of the active faults. Viewed from the earthquake-forecasting entirety, the authors hold that the active faults existent since Quaternary are closely related to the activity of Cangkou- Hot Spring active fault, geothermal anomaly, earthquake anomaly and geochemical anomaly in the hot spring basin.
