“…Similarly, basalts and CIPW-normative quartztrachytes from Oku and Bambouto (continental sector of the Cameroon Line, see Fig. 1) are considered as co-magmatic (Marzoli et al, 1999), despite a large gap between basaltic and felsic lavas.…”

“…La série intermédiaire à dominance trachytique et phonolitique d'âge Miocène (Nkouandou et al, 2008) est représentée par 35 necks, dômes et dômes-coulées. La série basaltique récente d'âge MioPliocène (10,0 à 7,0 ± 0,2 Ma et 11, 39 ± 0,03 à 9,28 ± 0,03 Ma) (Gouhier et Nougier, 1974;Marzoli et al, 1999 ;Nkouandou et al, 2008) est représentée par trois types de coulées basaltiques dont (1) les coulées inférieures et (2) supérieures essentiellement constituées de basalte (avec les ankaramites pour les coulées supérieures), affleurent respectivement dans les bas-fonds et aux sommets des collines et, (3) les coulées intermédiaires constituées de basalte, hawaiite et mugéarite affleurent sur les pénéplaines et les flancs des collines. Le volcanisme du Plateau de l'Adamaoua est très peu étudié par rapport au reste de la 'Ligne du Cameroun'.…”

Other plume-based models have been proposed, however, including multiple plumes impinging on the lithosphere, with volcanics from one hot spot track overprinting the linear age progression created by another [Ngako et al, 2006].…”

“…Volcanism continues to the present at both onshore and offshore volcanic centers. Although there is no evidence for age progression of volcanics along the onshore portion of the CVL [e.g., Hedberg, 1969;Grant et al, 1972;Grunau et al, 1975;Dunlop and Fitton, 1979;Cornen and Maury, 1980;Dunlop, 1983;Fitton and Dunlop, 1985;Lee et al, 1994;Ngounouno et al, 1997;Marzoli et al, 1999Marzoli et al, , 2000Ngounouno et al, 2001Ngounouno et al, , 2003Njilah et al, 2004;Ngounouno et al, 2005Ngounouno et al, , 2006Aka et al, 2009;Dongmo et al, 2010;Kamgang et al, 2010], some studies have suggested a possible seaward progression for the oceanic sector; however, this possibility remains unclear due to small numbers of samples [Grunau et al, 1975;Meyers and Rosendahl, 1991;Meyers et al, 1998]. Volcanics throughout the CVL consist primarily of alkaline basalts [Hedberg, 1969].…”
