Abstract. In the Pitoa-Figuil area (Northern Cameroon), an interpretation of aeromagnetic data was conducted. The aim of this investigation was first to emphasize lineaments hidden under geological formations and secondly to propose two 2.75D models of the subsurface structures. Different magnetic data processing techniques were used, notably horizontal gradient magnitude, analytic signal, and Euler deconvolution. These techniques in combination with the 2.75D modelling to the aeromagnetic anomaly reduced to the equator permit to understand the stratification of the deep and near surface structures, which are sources of the observed anomalies. We managed to put in evidence and characterize 18 faults and some intrusive bodies. According to Euler's solutions, anomaly sources go up to a depth of 5.3 km.

结构特征来自于皮托－菲吉尔地区（喀麦隆北部）航空数据的多尺度分析和2.75D建模

摘要。在喀麦隆北部的皮托－菲吉尔地区，对航磁数据进行了解释。这项研究的目的是首先强调隐藏在地质构造之下的地貌，其次提出两个地下结构的2.75D模型。使用了不同的磁数据处理技术，特别是水平梯度幅度，分析信号和Euler反卷积。这些技术与对减少到赤道的航空磁异常的2.75D建模相结合，可以了解深层和近层表面结构的分层，这是观察到的异常的来源。我们设法提供证据并描述了18个断层和一些侵入体。根据Euler的解决方案，异常源的深度可达5.3 km。
