摘　　要：汝州市温泉镇地热田是豫中典型的构造型地热田,受控于新安—平顶山断裂。通过同位素化学,结合区域地形、地质、构造研究及同构造其它地热田同位素对比分析,构建地热田形成机制。通过对研究区不同水体氢氧、碳氧、硫氧同位素的研究,证实地热流体是远程补给的,类比同一构造的新安暖泉沟、洛阳龙门地热流体同位素化学特征,推断三者可能是同源的。氢氧同位素计算补给高程为566~791 m,与控热断裂在新安县石井—石寺盆地一带高程接近。采用二氧化硅温标推断循环深度为2812~3109 m,与控热断裂在洛河褶断埋藏深度吻合。而温泉地热田则是地热流体不断与围岩物质、温度进行交换,在研究区遇阻形成的。The geothermal field is a typical structural geothermal field in Wenquan Town,Ruzhou City,Henan Province,which is controlled by the Xin'an-Pingdingshan fault zone.The geothermal fluid is recharged from a remote zone in the studied area.Based on the analysis of isotope,the geomorphology and geological structure characteristics of the geothermal field were combined to study this genesis system.Analogous to the isotope chemical characteristics of the Xin'an Nuanquangou and Luoyang Longmen geothermal fluids of the same structure,it is inferred that the three may be homologous.Hydrogen and oxygen isotope calculations have an elevation of 566~791 m,which is close to the elevation of the thermal control fault in the Shijing-Shisi Basin of Xin'an County.The silica temperature scale is used to infer the circulation depth of 2812~3109 m,which is consistent with the buried depth of the thermal control fault at the Luohe fold fault.On the other hand,the hot spring geothermal field is formed by the continuous exchange of geothermal fluid with surrounding rock material and temperature,which is formed when it encounters resistance in the study area.
