【摘要】 在长白山天池火山区及外围地区采集温泉和冷泉水样19个。计算了温泉水的热储温度和热储深度,分析了火山区地下热流体的化学组成特征及其变化规律。通过与外围地区的对比研究,发现Cl、F、B、Fe和Mn等组分是天池火山区深部热流体的特征组分,认为这些组分可能成为火山监测的灵敏组分。最后初步探讨了火山区水—岩平衡及浅层地下水的混合作用等问题。更多还原

【Abstract】 Ninteen samples are collected from the hot spring and cold spring in the Tianchi volcanic region and its surrounding areas. The reservoir temperature and reservoir depth of the hot springs are calculated. The characteristics and changes of the chemical compositions of the geothermal fluids in the volcanic region are analyzed. Based on correlations with the surrounding areas, Cl, F, B, Fe and Mn are found to be the typical components of deep geothermal fluids in the Tianchi volcanic region, and these components may possibly be used as sensitive components for monitoring volcanic activities. Also discussed are the water—rock interaction equilibrium and mixing of shallow groundwater in the volcanic region.更多还原
