Origin and paleoenvironment of Pleistocene–Holocene Travertine deposit from the Mbéré sedimentary sub-basin along the Central Cameroon shear zone: Insights from petrology and palynology and evidence for neotectonics

Erosion mode and history of Eastern Adamaoua landscapes (Cameroon): Superimposed lateritic weathering of granites and basalts

“…1b) also portray hillslope erosion that preferentially occurred on inherited litho-structural discontinuities (see also Sawadogo et al, 2020). Landscape physical rejuvenation was also previously observed in western highlands of Cameroon (Momo Nouazi et al, 2019) on Mid-Miocene basalts and trachytes, and possibly occurred during a period (i.e., Pliocene) of mechanical (clastic) erosion (Tchouatcha et al, 2010).…”

First evidence of sinter and travertine in Cameroon: fault reactivation and geothermal implications

“…Precambrian tectonic rejuvenation during Phanerozoic times are well documented [Le Maréchal and Vincent, 1971, Ngangom, 1983, Dumont, 1984, Njike Ngaha, 1984, Tchouatcha et al, 2010. They induced the Cenozoic thermo-metamorphism [Ngangom, 1983] that affected the basal Cretaceous conglomerates along the CCSZ in Djerem-Mbere [Tchouatcha, 2011, Tchouatcha et al, 2016 and are also related to the South Atlantic Ocean opening. In this particular context, the CVL represents a N30E megasplit stress related to the Pan African N70E leap reactivation [Cornacchia and Dars, 1983, Moreau et al, 1987, Deruelle et al, 1991, Montigny et al, 2004.…”

“…Despite the genetic link between travertine deposits and climate is well established [Kronfeld et al, 1988, Osmond and Dabous, 2004, Weisrock et al, 2008, Toker et al, 2015, Mancini et al, 2021, tectonics can also be determinant [Faccenna et al, 2008, De Filippis et al, 2013a. The link between travertines and active tectonics has been established [Tchouatcha et al, 2016[Tchouatcha et al, , 2018 and well known elsewhere [Altunel and Hancock, 1993, Altunel and Karabacak, 2005, Mesci et al, 2008, Brogi et al, 2012, 2020, 2021a,b, De Filippis et al, 2013b, Kanellopoulos et al, 2017, Matera et al, 2021.…”

Paleoenvironmental significance and provenance of the Cretaceous calcareous deposits from the Djerem sub-basin (Adamawa, Cameroon) during the Gondwana evolution: sedimentary structures and geochemical constraints

“…The travertines or calcareous tuffs are more observed in the East. These deposits of Pleistocene to Holocene age have been emplaced, thanks to the movements of adjacent faults [Tchouatcha et al, 2016].…”
