羊八井热田是属于陆陆碰撞板缘非火山型高温地热田。热田是由3个不同能的热储层构成，即浅层、深部第一和第二热储层，实质上它们属同一个水力系统，是一个完整的地热系统的不同部位。浅层热储由第四系松散沉积物及部分基岩风化壳构成，其埋深在地表以下180～280 m，热储温度130～173℃，水质类型为C1^--HCO₃^--Na⁺型水，属深部热流体与冷水混合的产物，流体以液相为主。深部热储由变质杂岩体中的滑离断层系构造空间构成，属基岩裂隙型脉状或带状热储，其中深部第一热储埋深为950～1 350 m，最高温度259.6 ℃；深部第二热储位于1 850 m深，热储最高温度可达329.8 ℃，深部热流体水质类型均属C1^--Na⁺ 型，气体组份中CO₂占主导地位。

The Yangbajing Geothermal Field is one of non-volcanic high-temperature geothermal fields. The Yangbajing convective system consists of two reservoirs at different depth. The shallow reservoir is constitued of loose alluvium of Quanternary and altered granite of Himalaya. Temperature inside the shallow reservoir is in the range of 150〜165℃ at the depth of 180〜280 m. Shallow thermal water is of sodium chlorite type and mixture of deep hot water and cold groundwater. The deep reservoir is in a slip-fault zone of the core complex. It is a veinor zone-shape reservoir. The deep reservoir can be divided into two parts. The upper parts of temperature 251℃ is at depths ranging from 950m to 1350 m. The lower part is below 1850 m , in which the measured temperature is as high as 329℃ . The deep thermal water is of sodium chlorite type, too. Carbon dioxide-is a major non-condensate gas in the shallow and deep reservoir.
