【摘要】 依据镜泊湖地区水体的同位素、水化学及微量元素中子活化分析资料,详细阐述了各采样点水体的来源、补给相对高程和它们之间可能的水力联系,以及有关的地热信息;分析了区内地热资源的有利地质背景条件研究区地处深大断裂及岩浆喷发带,火山喷发一直延续至第四纪全新世,有充分的热源供给;区内上部为较厚的玄武岩覆盖,有利于储存地热;下部白垩系上统为主要含水层,发现有广泛分布的典型水 岩热蚀变产物———斜发沸石,进而证明存在地下热水的可能性。更多还原

【Abstract】 Based on the information of isotope composition and element analysis data in Jingbohu, this paper traces pathway, and analyses the recharge altitude, hydraulic connection in different water bodies in this research area and information about deep geothermal source. This paper also analyses the advantage condition of regional geology background for geothermal resource. Jingbohu is located in deep faults and volcano activity zone, so it has sufficient heat energy to supply. In this area, upper layer is thicker basaltic lava that is beneficial to store geothermal resource. The lower layer is the main highly phreatic Cretaceous strata, and enriches hydrothermal alteration product-clinoptilolite ledge, so we could demonstrate the possibility of existence of geothermal water.更多还原
