Abstract

Background

this paper reviews the results obtained from recent studies mentioning the crustal architecture in Cameroon. It also discusses the study of [1] “Estimation of Curie depth, geothermal gradient and near-surface heat flow from spectral analysis of aeromagnetic data in the Loum-Minta area (Centre-East Cameroon)”. The paper published by [1] is an application of the spectral method for the determination of Curie depths, followed by interpretations on the local thermal structure (thermal gradient, heat flux) of the crust. However, some outliers are remarkable and depend at first analysis on a bad mesh of the data following a windows of 27.75 * 27.75 km. Similarly, the failure to take into account the various parameters (seismic, geological, tectonic) which would help to better calibrate the results.

Discussion

with this communication, we would like to mention and clarify some errors in the paper published by [1] based on a global review of thermal behaviour of the crust.

Summary

It is strongly recommended that information on regional geology and seismicity be used to estimate the Curie depths and that other independent data be integrated to determine the thermal and mechanical behaviour of the crust in Cameroon.

关于“根据loum minta地区（喀麦隆中东部）航磁数据的光谱分析估算居里深度、地热梯度和近地表热流”的讨论

本文综述了近年来有关喀麦隆地壳构造的研究成果。本文还讨论了[1]“通过对Loum-Minta地区(喀麦隆中东部)航磁数据的频谱分析估算居里深度、地温梯度和近地表热流”的研究。[1]发表的论文应用谱法确定居里深度，进而解释地壳局部热结构(热梯度、热通量)。然而，一些异常值是显著的，并且在最初的分析中依赖于27.75 * 27.75 km窗口后的数据网格。同样，未能考虑到有助于更好地校准结果的各种参数(地震、地质、构造)。在讨论这一信息时，我们想提到并澄清[1]发表的基于地壳热行为的全球综述的论文中的一些错误。强烈建议使用区域地质和地震活动信息来估计居里深度，并综合其他独立数据来确定喀麦隆地壳的热力学行为。

期刊介绍： Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
