长白山温泉资源丰富，包括锦江温泉群、巨龙温泉群等，是我国温泉资源开发的重要地区。采用水文地球化学分析、同位素分析、岩样分析、水文地球化学模拟和地球物理勘探等方法，对晋江温泉和聚龙温泉的水文地球化学特征和概念成因模式进行了评价。结果表明，温泉中HCO 3-和Na+是最丰富的阴、阳离子，水化学类型为Na-HCO 3。晋江温泉和巨龙温泉的气体成分主要为CO2、N2和CH 4，来源于地幔。其化学成分主要由长石和辉石矿物水解而成。温泉的补给来源为大气降水，同时也受蒸发作用的影响，锦江温泉和聚龙温泉的成因模式均为：热源为岩浆体，热量主要以热传导形式迁移。盖层均为白头山组粗面岩、军尖山组玄武岩和长白组流纹质火山碎屑岩。两个温泉的热储层均为裂隙带，岩性分别为火山角砾岩、砂、砾石和火山角砾岩、大理岩。
Changbai Mountain in China has been explored as a potential area for its rich hot springs including the Jinjiang and Julong hot spring groups. The hydrogeochemical characteristics and conceptual genesis models of the Jinjiang and Julong hot springs were evaluated by hydrogeochemical analysis, isotope analysis, rock sample analysis, hydrogeochemistry simulation, and geophysical exploration method. The results showed that HCO3− and Na+ were the most abundant anion and cation in the hot springs, and the hydrochemical type was Na-HCO3. And the hot springs are enriched with trace components such as H2SiO3 and Sr. The major gas composition of the Jinjiang hot springs and Julong hot springs were CO2, N2, and CH4, which were derived from the mantle. The chemical compositions were produced by feldspar and pyroxene mineral hydrolysis. The recharge source of the hot springs was atmospheric precipitation and was also influenced by evaporation, and the genetic models for the Jinjiang hot springs and Julong hot springs were as follows: the heat source of both was a magma body and heat was mainly migrated in the form of thermal conduction. The cap rocks were both composed of trachyte of Baitoushan formation, basalt of Junjianshan formation, and rhyolitic pyroclastic rocks of Changbai formation. The geothermal reservoir of both hot springs was a fracture zone with the lithology of volcanic breccia, sand, and gravel and volcanic breccia and marble, respectively.
