| Abstract | The region of Adrar is located in south - western Algeria, covers a total area of 443.800 km² and is occupied by a population of 432,193 inhabitants. The main activity of the population is agriculture, mainly date palm cultivation occupying a total area of 23,532 ha. The climate of Adrar region is continental desert characterized by a high variation in temperatures exceeding 48°C between July to August and 16°C between December to January. The rainfall is very limited in frequency and volume with an aridity index of 4.6 to 5.0 which corresponds to a typical arid climate. Geologically Adrar region, located on the edge North Westand is characterized by a Precambrian basement covering stolen sedimentary deposit of Phanerozoic age transgressively. The depression is filled by Touat site Paleozoic deposits (Cambrian to Namurian) of a vast sedimentary basin extending secondary age of the Saharan Atlas to the North of hamadaTinhirtTademaït, the plateau to the South, TouatGourarato the West and Gulf of Gabes in the Northeast. This work outlines a study of the geothermal potential of Adrar region from the borehole data in various sites across the area of 400,000 km². From the data we developed distribution plots of the data of the various points and boreholes in the region specifying information on available geothermal potential at various depths. |
