“Critical Study of U-Pb Ages on Zircons in the Touareg Shield’’ (2021) –With the collaboration of Yasmine SAIDI and the supervision of Riad BEN EL KHAZNADJI & Abderahman BENDAOUD at University of Science and Technologie Houari Boumediene (STU-FSTGAT), Algeria.
This study aims to establish a comprehensive review of U-Th-Pb zircon ages calculated in the Touareg Shield, covering the period from 1965 to 2020, with a specific emphasis on the Hoggar region. The focus on this timeframe is particularly significant as a thesis published in 2021 used the same software, IsoplotR, and while the results from this source are indeed valuable, they were not integrated into our comprehensive database. Nevertheless, these results informed interpretations in the latter part of our study. Expanding upon our initial database, we incorporated previously unpublished data from an underexplored geological terrane. The results did allow us to :
Acknowledge the identification of a Paleoproterozoic unit which portrays a possible signification of a same prior block in the Western part of the Touareg Shield (Algeria and Mali) fragmented latter (hypothesis).
Provide a duration of the Eburnean event, around 100 million years, from 2.0 Ga to 1.95 Ga.
Indicate the occurrence of a possible rift - 1.8 Ga - in the Eastern part of the Western Hoggar.
