The Lokoundje alluvial clay deposits are located at the left floodplain of the Lokoundje River, towards the estuary in the Kribi region. The mineralogical and geochemical features of the Lokoundje River fine-grained sediments have been reported using XRD, XRF, ICP-MS, and IR instruments in order to understand their provenance and depositional history. The Lokoundje watershed covers a surface area of about 5381 km2. The basement of this watershed is made up of gneisses, amphibolites, migmatites, ...

Eight kaolinitic materials from the Lokoundje River at Kribi were sampled and investigated for their physical, chemical, mineralogical and thermal characteristics in order to evaluate their potential suitability as raw materials in ceramics. The Lokoundje kaolinitic materials are clayey to silty clayey and are predominantly composed of kaolinite and quartz. The alkali (Na2O + K2O) content ranges between 1 and 2.5 wt.%; these low values do not favor vitrification of the ceramics but may be improved ...
