| 中文摘要: |
| 结合马岔河区域内多年的水质分析、监测资料,系统阐述了马岔河温泉水文地球化学特征,利用同位素手段,分析了马岔河温泉的水源、补给区高程；利用Na-K-Mg三角图解法判断水岩平衡状态,判断结果为马岔河温泉属于未成熟水,只能利用SiO2温标计算温泉的热储温度。通过分析,认为其水源为大气降水,热源为深循环加热,热储温度72.33℃ ,热储深度为2 690 m。马岔河温泉的地质成因为: 在正常区域地热场环境中,大气降水沿高渗透率的岩石渗入地下,深部地下水沿断层破碎带向马岔河运移,循环加热,深部地下水在马岔河断束上涌汇集,并与近源低温地下水混合,在地势低洼处出露形成温泉。 |

| According to the water analysis and monitoring information of Machahe area in recent years, the hydrological geochemical characteristics of Machahe thermal spring are introduced. By isotope method, the water head, supply area temperature and attitude analysed. By Na-K-Mg triangle graphic method, the water-rock balance state judged, the Machahe thermal spring is not balance water, it can only use SiO2 thermometric scale to calculate geothermal reservoir temperature. By analyses, it’s thought the water head is atmospheric water, the heat source is deep-cycle heating, geothermal reservoir temperature is 72.33℃ and the depth is 2 690 m. the genetic model of Machahe thermal spring is:in the normal geothermal field, the atmospheric water seep into underground along high permeability rock, the deep groundwater transit to Machahe along the fracture and cycle heating, deep groundwater concentrates in Machahe and mix with nearby low-temperature groundwater, the thermal spring formed in the low area finally. |
