Paleoenvironment of the Mfamosing Limestone, Calabar flank, southeastern Nigeria. – N. U. Essien and D. O. Ufot
Microfacies analyses of outcrops samples and cores from two (2) wells were used in the determination of the paleoenvironment of the Mfamosing Limestone. Pelbiomicritic mudstone – wackestone, algal stromatolitic boundstone, oobiosparitic packstone – grainstone, intrabiosparitic packstone and biosparitic grainstone – packstone microfacies types were identified. These were used to infer lagoonal complex, tidal flats and channels, carbonate shoals and shelf margins with open circulation paleoenvironments respectively for the Mfamosing limestone.
