Research ArticleOpen accessIn the author namesLithofacies and Depositional Environment of Volcano-Sedimentary Deposits of Se Mayo Oulo BasinElie Fosso Menkem, David Sebag, Benjamin Ngounou Ngatcha, Alain DurandThe study of volcano-sedimentary deposits of Mangbai in SE Mayo Oulo basin-Cameroon leads to the identification of five major distinct lithofacies types. From the coarset to the finest lithofacies, there are: Gb-clast supported by massive coble and boulder, Gg-granule to massive gravel, Sm-massive sand, Sh-horizontal layered sandstones, Fml-massive laminated claystones. Coarse facies (Gb, Gg, Sm) are cemented with volcanic matrix … …Current Research in Geoscience, Vol. 3, Issue 2 · 19 Dec 2013 · 7,375 accessesView PDFCite
