Petrology and geochemistry of the Yoro-Yangben Pan-African granitoid intrusion in the archaean Adamawa-Yade crust (Sw-Bafia, Cameroon)

Zircon trace element geochemistry and Ti‐in‐zircon thermometry of the Linté Pan‐African granitoids, Central Cameroon: Constraints on the genesis of host magma and tectonic implications

“…This observation is consistent with the whole‐rock geochemical and geochronological results obtained from the Linté granitoids characterized by LILE‐enrichment, HREE‐ and HFSE‐depletion, and distinct negative Nb‐Ta anomaly, which are typical of subduction‐related settings (Ayonta et al, Unpublished data of the authors'). Similar tectonic setting was recently proposed by Ngamy Kamwa et al (2019) in the Yoro‐Yamben area and by Hamdja Ngoniri et al (2021) in the Ngazi Tina area. The findings of this study conform to the N‐S geodynamic collision model between the AYD and the northern border of the Congo Craton, resulting in crustal thickening, sub‐crustal lithospheric mantle delamination, and upwelling of the asthenosphere (Goussi Ngalamo et al, 2017, and references therein).…”

“…New metamorphic events have been put forward by Ngnotué et al (2012) showing ages ranging from Tonien to Stenien in the Yaoundé Series (911–1,122 Ma; U–Pb age on zircon of metapelites) and interpreted as the beginning of metamorphism in the Yaoundé Group. The AYD or Central Cameroon domain is dominated by syn‐ to late‐collisional high‐K calc‐alkaline granitoids (e.g., Chebeu et al, 2011; Kouankap Nono et al, 2010; Ngamy Kamwa et al, 2019; Njanko et al, 2006; Nomo et al, 2017; Nzenti et al, 2011; Nzenti et al, 2006; Nzina Nchare et al, 2010; Nzolang et al, 2003; Tanko Njiosseu et al, 2005; Tchakounté et al, 2017). These granitoids intrude high‐grade gneisses that represent the Archean to Palaeoproterozoic basement, which was likely dismembered during the Pan‐African reconstitution of western Gondwanaland (Ganwa et al, 2008; Tanko Njiosseu et al, 2005; Tchakounté et al, 2017; Van Schmus et al, 2008).…”

“…The Central African Fold Belt (CAFB) in Cameroon has witnessed substantial crustal accretion during the Pan‐African Orogeny (650–550 Ma), leading to the widespread occurrence of granitoids (Abdelsalam et al, 2002; Nzenti et al, 1998; Nzenti et al, 2007; Toteu et al, 2004). These rocks have received considerable attention, as indicated by the abundant available literature (e.g., Chebeu et al, 2011; Djouka‐Fonkwé et al, 2008; Kouankap Nono et al, 2010; Kwekam et al, 2010; Ngamy Kamwa et al, 2019; Njanko et al, 2006; Nomo et al, 2017; Nzenti et al, 2006; Nzina Nchare et al, 2010; Nzolang et al, 2003; Tagne Kamga, 2003; Tanko Njiosseu et al, 2005; Tchakounté et al, 2017; Tchameni et al, 2006; and references therein). These studies have improved our understanding of the magma sources, petrogenetic processes, and involvement of juvenile and/or recycled material, emplacement ages, and tectonic settings of the CAFB.…”

Landsat-8 OLI/SRTM and gravity characteristics of the Pan-African fracture aquifers of the north central Cameroon region (central Africa)

“…The structural measurements obtained during the field campaigns helped to interpret and validate the geological structures (lineation and fractures) mapped using satellite images. Structural geology data were employed due to the dearth of outcrops and their significant alteration [ 42 , 43 , [78] , [79] , [80] ]. Table 2 's field information reveals a total of 120 fracture directions.…”

Geochemistry of the Neoproterozoic Mbondo-Ngazi Tina Metasediments, Adamawa Area, Central Cameroon: Source Provenance and Tectonic Setting

“…Of these three domains, the central domain or Adamawa-Yade Domain (AYD) has been widely investigated for the past two decades, but their geodynamic evolution remains controversial and/or unrevealed. Many studies have been mainly concentrated on petrogenesis of granitoids which are widespread in the central domain [7][8][9][10][11][12][13][14][15] and only few works on the metamorphic rocks [7,16,17,18,19] In comparison to the granitoids, the metamorphic rocks, especially metasedimentary rocks from the central domain have received very little attention even though sedimentary rocks contain a wealth of information about provenance and crustal evolution [20,21]. It is now well established that detrital sediments contains part of a record of geologic history.…”
