Abstract

Lavas on the oceanic and continental sectors of the Cameroon Volcanic Line (CVL) present similarity in geochemical and isotopic compositions but with no evidence of systematic age migration. Oku Volcanic Group (OKVG) lavas are slightly different from other continental CVL lavas. We present preliminary results of major (XRF) and trace elements (ICP-MS) of some mafic lavas from the OKVG.
