Abstract	The present study identifies the hydrochemical and isotopic properties of the Mahmutlu and Bağdatoğlu mineralized thermal springs in Kırşehir province, a geothermal field in central Anatolia, Turkey. Based on these properties, a hydrogeological regime is proposed in order to explain the Mahmutlu–Bağdatoğlu geothermal system. The relation between the concentrations of the environmental stable isotopes deuterium and oxygen-18 in the water is similar to the relationship in global meteoric water, indicating that the water is of meteoric origin. Evaluation of the geochemical characteristics of the water reveals that these two thermal springs belong to the same hydrogeological system. The hydrogeological system comprises a fractured limestone member of the Çevirme Formation and the Kervansaray Formation as reservoir rocks, and the Deliceırmak Formation as an overlying aquitard. The waters of the Mahmutlu and Bağdatoğlu springs are mainly of the Na-Cl-SO4 type that originate from the Pohrenk evaporite. The thermal waters are undersaturated with respect to calcite, dolomite, halite, and gypsum. The δ 18O and δ 2H contents indicate a δ 18O shift in the Mahmutlu and Bağdatoğlu waters. The temperature range of the two reservoirs is estimated to be 98–158 °C, on the basis of Na+K+Ca and SiO2 geothermometers.Cette étude présente les caractéristiques chimiques et isotopiques des sources thermales minéralisées de Mahmutlu et de Bağdatoğlu, dans la province de Kırşehir, un champ géothermal d'Anatolie centrale (Turquie). Un fonctionnement hydrogéologique est proposéà partir de ces caractéristiques, permettant d'expliquer le système géothermal de Mahmatlu-Bağdatoğlu. La relation entre les teneurs en deutérium et celles en oxygène-18 des eaux est semblable à celle des eaux météoriques mondiales, ce qui indique que l'eau est d'origine météorique. Les caractéristiques géochimiques des eaux de ces deux sources montrent qu'elles appartiennent au même système hydrogéologique. Ce système hydrogéologique est constitué d'un ensemble calcaire fracturé, appartenant à la formation d'Evirme, et la formation de Kervansaray, qui forment le réservoir, et la formation de Deliceırmak, qui est l'imperméable de couverture. Les eaux de Mahmutlu et de de Bağdatoğlu sont essentiellement de faciès Na-Cl-SO4, dont l'origine est l'évaporite de Pohrenk. Les eaux thermales sont sous-saturées par rapport à la calcite, à la dolomite, à la halite et au gypse. Les teneurs en δ 18O et en δ 2H indiquent un fractionnement de δ 18O dans les eaux de ces sources. La gamme de températures des deux réservoirs est estimée à 98-158 °C, à partir des géothermomètres Na+K+Ca et SiO2.
