| 摘 要： | 根据对山东半岛地热场特征、区域地质构造、岩浆活动与温泉分布关系的研究以及地热水化学特征的分析，认为温泉的形成与分布主要受断裂构造的控制。温泉的形成机理为深循环－地热增温，即大气降水或第四系潜水沿断裂带深循环，在正常地温梯度下吸收地球内热增温形成热水，再沿断裂破碎带上涌至地表而形成温泉。温泉水温取决于地下水循环深度，按笔者提出的经验公式推算，山东半岛１４处温泉水的最小循环深度界于１５０３～３０８４ｍ间。温泉水循环深度大致指示控泉断裂构造发育的最小深度

| Abstract: | According to the research on the relationships among the characters of geothermal field, regional geological structures, magmatic activities and the distribution of warm springs in the Shangdong Peninsula and the analyses of the hydrochemical characters in geothermal water, the authors consider that the distribution of warm springs is mainly controlled by fracture structures. Atmospheric precipitation or Quarternary ground water circulates along the fracture belt, increasing its temperature by absorbing the inner heat of the Earth and becoming geothermal water. Geothermal water rises along the fracture belt to the surface, exposes and forms warm springs in river valley and terrace of littoral area. The temperature of a warm spring depends on the circulation depth of the ground water. On the basis of the empirical formula put forward by the authors, the smallest circulation depths of warm spring waters in the Shandong Peninsula are calculated and range from 1503 to 3084 m. The circulation depths of warm spring waters roughly represent the developing depths of the fracture structures of controlling springs. |
