The In Teria region is located South-East of Algeria, in the North-East of the Illizi basin. Generally, this area is recognized as a volcanic region with circular craters controlled by faults. In this research, structural lineaments were extracted using aeromagnetic data and satellite images (Landsat 8 OLI TIRS), and the direction of distribution of volcanic craters was analyzed by the center-to-center method. The mains observations show, at different structural levels, the following results: 1- the directions of the surface lineaments are E-W, WNW-ESE and ENE-WSW while those of crustal scale are N–S, E-W, NNW-SSE to NW-SE. 2- The volcanic craters are located at the intersection of these two directions (E-W and NW-SE) with the N–S lineaments. Some of these directions are linked to a reactivation of Pan-African mega-shear zones (N–S, NW-SE to NNW-SSE) during the Cenozoic, and some others (NW-SE and NNW-SSE) had already been reactivated during the Cretaceous rifting. 3- The depth estimation methods used thanks to Euler deconvolution and Tilt derivative showed, for the first time, the presence of magnetic anomalies related to magmatic bodies at a shallow depth of 2.5–3 km. The spectral analysis method gave a depth of more than 11 km for the deep sources. 4- The depth of the basement estimated by 2D forward modeling according to an N–S profile which passes through the outcrop zone of the craters, varies from 200 to 6000 m. All these data and new results presented in this work helped to highlight on the dynamics of In Teria's volcanism and to derive an updated structural mapping of this volcanic region.

In Teria 地区位于阿尔及利亚东南部，伊利齐盆地的东北部。通常，该地区被认为是一个火山区，具有受断层控制的圆形火山口。在这项研究中，结构线条利用航磁数据和卫星图像（Landsat 8 OLI TIRS）提取了火山口的分布方向，并通过中心到中心的方法分析了火山口的分布方向。干线观测表明，在不同构造层次上，结果如下： 1-地表线状方向为EW、WNW-ESE和ENE-WSW，地壳尺度方向为N-S、EW、NNW-SSE至NW-东南。2- 火山口位于这两个方向（EW 和 NW-SE）与 N-S 线的交点处。其中一些方向与新生代泛非大剪切带（N-S、NW-SE 到 NNW-SSE）的重新激活有关，而其他一些方向（NW-SE 和 NNW-SSE）已经重新激活在白垩纪裂谷期。3- 使用 Euler 的深度估计方法反褶积和倾斜导数首次表明在2.5-3 km的浅层存在与岩浆体相关的磁异常。光谱分析方法给出的深源深度超过 11 公里。4- 根据穿过陨石坑露头区的 N-S 剖面，通过 2D 正向建模估计的基底深度从 200 到 6000 m 不等。这项工作中提出的所有这些数据和新结果有助于突出 In Teria火山活动的动态，并得出该火山区的最新结构图。
