这项研究解释了摩洛哥高地图集地块Tizin\'试验区的航磁数据,旨在深入了解其岩性结构架构以及对矿产勘探和开采的影响。我们对剩余磁场数据采用了六种不同的分析技术,包括减少到极点(RTP),向上延续,总水平导数,倾斜角度,勘探目标确定中心(CET)分析,和欧拉反卷积。我们的分析将研究区域分为三个磁畴:东部Ouzellarh块,以积极异常为特征,一个中央域,其特征是负磁特征,划定了由Ouchden断层隔开的反Atlas和高Atlas之间的过渡区:和西部域,以蒂奇卡地块为代表。总水平导数的应用,倾斜角度,和三元图像格式的过滤器组合(倾斜角度,向上延续1000+倾斜角度和向上延续3000+倾斜角度)揭示了已知和先前未确定的地质谱系,在不同方向上绘制结构复杂性(NE-SW,NNE-SSE,E-W,NW-SE,和N-S)。CET网格分析方法揭示了结构的复杂性,突出该地区的地球动力学演化。特别是,Ouchden断层描绘了古代高Atlas和Ouzellarh区块(反Atlas)之间的磁畴鸿沟。此外,Euler反卷积表明,磁源深度范围从Tichka地块西域的52m到Ouzellarh区块的6560m。全面的结构方案,通过C-A分形分析分类,确定有利于勘探和采矿的区域,尤其是Ouchden断层,Tizin\'测试,西北区域的NE-SW趋势线,以及沿着蒂奇卡花岗岩的边缘。
This study interprets aeromagnetic data from the Tizi n\'Test area in the High Atlas massif of Morocco, aiming to gain insights into its litho-structural architecture and implications for mineral exploration and mining. We employed six different analytical techniques to the residual magnetic field data, including reduction to the pole (RTP), upward continuation, total horizontal derivative, Tilt angle, Centre for Exploration Targeting (CET) analysis, and Euler deconvolution. Our analyses differentiated the study area into three magnetic domains: the eastern Ouzellarh block, characterized by positive anomalies, a central domain characterized by a negative magnetic signature demarcating the transitional zone between the Anti-Atlas and the High Atlas separated by the Ouchden fault: and the western domain, represented by the Tichka massif. The application of total horizontal derivative, tilt angle, and a combination of filters in ternary image formats (Tilt angle, upward continuation 1000 + Tilt angle and upward continuation 3000 + Tilt angle) revealed both known and previously unidentified geological lineaments, mapping structural complexity across various orientations (NE-SW, NNE-SSE, E-W, NW-SE, and N-S). The CET grid analysis method unveiled the structural complexity, highlighting the geodynamic evolution of the region. Particularly, the Ouchden fault delineates a magnetic domain divide between the ancient High Atlas and the Ouzellarh block (Anti-Atlas). Furthermore, Euler deconvolution indicated magnetic source depths ranging from 52 m in the western domain of the Tichka massif to 6560 m in the Ouzellarh block. A comprehensive structural scheme, classified by C-A fractal analysis, identified zones favourable for exploration and mining, particularly along the Ouchden fault, Tizi n\'Test, NE-SW trending lineaments in the northwestern domain, as well as along the Tichka granite\'s margin.
