Deep structures imaging of the INOUZZAL Archean terrane (HOGGAR, ALGERIA) from the Inversion of Aeromagnetic Profiles
Abstract
Delineating hidden contacts of deeply located geological structures and determination of their spatial configuration has always been an important task during the analysis and the inversion of potential field data. In this work, we will present the results obtained with the inversion of aeromagnetic profiles above the Inouzzal Archean Terrane (IAT), situated in the Western part of the Hoggar shield (Algeria) using the multiple-source Werner deconvolution and the wavelet transform techniques. Based on a synthetic models study, both mentioned techniques have shown a high performance and a great stability, yielding correct source boundaries location and very good estimation of dip angles. The interpretation performed on aeromagnetic profiles correlates well with the known geological structures of the studied area. However, the western boundary of the hidden part of the IAT, has been clearly identified and located. The dip angles of both the eastern and the western boundaries of this structure have been estimated, as well. The results inferred from the inversion of the aeromagnetic data are very useful to replace the IAT in the global structural context of the Hoggar shield.
