Abstract
This note is a comment to the article « The Cu–Pb–Zn-bearing veins of the Bou Skour deposit (Eastern Anti-Atlas, Morocco): structural control and tectonic evolution » by Aabi et al., published online on May 04, 2021, in Comptes Rendus Geoscience in Volume 353, 2021, pages 81–99 (https://doi.org/10.5802/crgeos.54). The authors’ response to this comment has also been published in Comptes Rendus Géoscience in Volume 354, 2022, pages 125–130 (https://doi.org/10.5802/crgeos.117).
Highlights
IntroductionMain faults system NNW–SSE to WNW–ESE, N–S to NNE–SSE, and NE–SW to ENE–WSW
The authors focus on tectonic analysis of structures and veins to discuss the fracturing–mineralization relationships (Figure 1)
Main faults system NNW–SSE to WNW–ESE, N–S to NNE–SSE, and NE–SW to ENE–WSW. They lay emphasis on the main tectonic events which controlled and postdated the ore structures and assign them to episodes spanning from the last stage of the Pan-African orogeny to the Variscan or Atlasic shortening
Summary
Main faults system NNW–SSE to WNW–ESE, N–S to NNE–SSE, and NE–SW to ENE–WSW They lay emphasis on the main tectonic events which controlled and postdated the ore structures and assign them to episodes spanning from the last stage of the Pan-African orogeny to the Variscan or Atlasic shortening. This poly-phased tectonism has been previously inferred from varied studies [Clavel and Tixeront, 1971, Startsyne et al, 1975, Harfi, 1984, Walsh et al, 2008, 2012, El Azmi et al, 2014, El Ouardi et al, 2015, 2016, Bouabdellah et al, 2016]. We would like to only discuss the tectonic model for the Bou Skour vein system by Aabi et al [2021] and the regional integration of the shear deformations occurring along the NNW–SSE trending mineralized veins [El Ouardi et al, 2016]
