Abstract:
Beka area is situated in the Adamaoua Plateau of Cameroon in central Arica. Lavas in this area has not been studied before the present work.The volcanism of Beka is characterized by basalt, trachyte and phonolite domes and flows. The petrographic study shows that basaltic lavas have porphyritic microlitic textures. The felsic lavas indicate trachytic textures.The rocks are composed of olivine, clinopyroxene,... More
Abstract:
Mount Cameroon is a Plio-Quaternary volcanic massif, without a central crater, made up of more than 140 pyroclastic cones. It is one of the active volcanoes of the Cameroon Volcanic Line. Mount Cameroon melt inclusions are found in microdroplets trapped in the early minerals (olivines) from the pyroclastic products. The analysis of these melt inclusions allowed us to find primitive liquids... More
