The Triassic province is located within the Eastern Algerian Sahara, towards the Eastern edge of the M'zab Dorsal. Several hydrothermal reservoirs have been identified within this area along the Oued Righ valley and Rehabi-Berriane structural axis, forming an area of high temperature geothermal activity. The genetic mechanism of this geothermal system is currently unclear and needs urgent scientific reaction. In this work, we present a new conceptual model of the geothermal system in the Triassic provinces, using the structural model obtained through integrated study of recent edge detection techniques and the calculation of thermal proprieties of the middle and the lower crust. This multidisciplinary approach proposes a novel heat transfer mechanism and reservoir architecture within the province. We used spectral analysis on aeromagnetic data to determine the Curie point depth, geothermal gradient, heat flow, and radiogenic heat production. The results outlined the major structural trends within the Eastern Algerian Sahara. Deep heat flow sources were observed between 12.5 to 23 km depths and the geothermal gradient within the lower crust reaches 35 °C/km. The measurement of the thermal properties in petroleum wells indicates different thermal distributions. The delineated geothermal pattern is linked to the deformation of the Moho and the presence of deep-seated faults along the middle and lower crustal boundary. The shallow Curie point depth can be interpreted to be a result of the crustal thinning giving the high heat flow values. These results provide a physical representation of the heat transfer modes in the Oued Righ and constitute a unique continuous geothermal system within the eastern Algerian Sahara.

三叠纪行省位于阿尔及利亚东部撒哈拉沙漠中，靠近 M'zab 背侧的东部边缘。在该地区沿 Oued Righ 河谷和 Rehabi-Berriane 构造轴发现了多个热液储层，形成了高温地热活动区。该地热系统的成因机制目前尚不清楚，急需科学反应。在这项工作中，我们提出了一个新的三叠纪地区地热系统概念模型，使用通过综合研究最近的边缘检测技术和中下地壳热特性计算获得的结构模型。这种多学科方法在省内提出了一种新的传热机制和水库结构。我们对航磁数据使用光谱分析来确定居里点深度、地温梯度、热流和放射热产生。结果概述了东阿尔及利亚撒哈拉地区的主要结构趋势。在 12.5 至 23 公里深度之间观察到深部热流源，下地壳内的地温梯度达到 35 °C/km。油井热特性的测量表明不同的热分布。描绘的地热模式与莫霍面的变形和沿中下地壳边界的深部断层的存在有关。浅居里点深度可以解释为地壳变薄导致高热流值的结果。
