	The Bellezma Mounts, located in the northeast of Algeria, present cases of hydrothermalism with temperatures ranging between 30{\textdegree} C and 63{\textdegree} C. For the evaluation of the thermal potential of this dissymmetrical mountains chains (often rectified in the South, where Cretaceous and Jurassic limestones emerge), we used a multidisciplinary approach, notably geology, geophysics, hydrogeology, hydrochemistry and the isotopic tool. Hydrogeological investigations have shown that these carbonate formations can offer an important aquifer potential. From the hydrochemical point of view, the warm waters of the Bellezma mounts are characterized by the presence of three different chemical facies: the sulfated-sodium, the bicarbonate-calcium and the chloride-calcium. Evaporite terrigenous origin is attributed to sodium, chlorides and sulphates of these waters. The thermal waters circulation in this region, at great depths in the crystallophyllian formations and the carbonate ones, in contact with terrigenous salt formations, could be responsible of the salinity characterizing these waters, in some places. Geothermometry has shown that these thermal waters acquire a high temperature in their original tanks coming from a depth ranging from 1100 to 2600 m through a fault system that affects the basement. The use of the isotopic tool has shown that the thermal waters of this region are ancient and that their recharge is weak or non-existent.
