| 摘 要： | 据地下水中ＳｉＯ２含量计算山东半岛硅热流值。以此为基础初步探讨本区的地热场特征及其与区域地质条件的关系。指出：１．山东半岛平均热流值与全球平均热流值接近，但比一般古老地块略高。２．划分出三个地热异常区，在大地构造上，两较高热异常区分别对应于胶北和文登隆起；较低热异常区与胶莱盆地相应。３．地热场总特征及其区域热异常的形态主要与近地表的地层岩性、构造形态和断裂发育程度等地质条件有关，而与中生代的岩浆活动无关，但第四纪岩浆活动对胶北隆起局部（蓬莱一带）热异常有重要作用

| Abstract: | The silica heat flow was calculated in the Shandong Peninsula by silica content in the underground water. Based on the silica heat flow the relationship between the characteristics of geothermal field and the regional geological conditions was preliminarily studied. The average heat flow value in the Shandong Peninsula is close to its global average value and higher than other ancient continental segments. The authors further divide them into three geothermal anomaly areas. The two higher geothermal anomaly areas of these correspond to the Jiaobei Rise and the Wendeng Rise, respectively; a lower geothermal anomaly area of these corresponds to the Jiaolai Basin in geotectonics. The whole character of the geothermal field and the origin of the regional geothermal anomaly mainly relate to regional geological conditions which are of lithological character of strata, structural forms, development of fractures, and so on, occurred during the evolutionary process of the crust. Only Quaternary magmatic activity had an influence on the local geothermal anomaly in the Jiaobei Rise. |
