Tectono-sedimentary evolution of the Senhaja Basin (Western Meseta, Morocco) and its implication for understanding the late Variscan tectonic processes

Popis výsledku v původním jazyce

During the final stage of the Variscan Orogeny, a series of intermontane basins developed along the present-day northwestern margin of Africa, predominantly within the Western (Moroccan) Meseta. Among them, the Senhaja Basin, located in the eastern Jebilet Massif, plays a key role in interpreting diachronous evolution of those basins. Whilst traditionally considered to have formed synchronously under similar geodynamic conditions, recent evidence suggests a more complex and diachronous development. The depositional environment of the Senhaja Basin is dominated by a fluvial system, characterized by a diversity of facies ranging from the alluvial fans in its proximal part to lacustrine deposits in its distal part. The alluvial-fan gravels feature the coarsest material deposited within the Senhaja Basin. Integration of sedimentological and structural data supports the interpretation of the Senhaja Basin as a pull-apart basin formed in response to NE-SW compression, accompanied by localized NW-SE extension. Comparative analysis with other Late Paleozoic basins in Morocco reveals the existence of two distinct generations of basins that evolved diachronously under varying tectonic regimes-ranging from compressional to extensional settings-whilst exhibiting similarities in sedimentary infill. These findings contribute to the broader discussion on the geodynamic evolution of late orogenic basins in the Moroccan Meseta and their implications for Late-Variscan tectonic reorganization.
