Abstract:Mass movements in form of subsidence, landslides and solifluxion are encountered within the sources of some water bodies in Bui division North West Region of Cameroon, to which little attention is given and assumed to be of supernatural, hence mystical with unquestionable origin. Subsidence within these sources results to land loss with degradation of the integrity of the infrastructure and ecosystem health. Despite the huge impact on the local landscape, the precise cause of the subsidence and related movements are not well understood. Contemporary research works elsewhere on similar aspects attributes a measurement of these movements to many different processes. Individual subsidence studies often focus on a particular subsidence process and use alternative methodologies whose results may not be comparable with or complementary to results of other studies. The hydrolysis of the dominantly feldspar minerals from the volcanic rocks within the locality produces Kaolinite as a secondary stable mineral. Kaolinite with its typical layering structure whose layers are held by predominantly weak hydrogen bonds in halloysite the hydrated form favour sliding movement between the layers that is enhanced by the overbearing weight load of the overlying earth strata, with subsidence often accompanied by Landslides as a consequence. This impedes attempts to synchronize the research into a comprehensive local and regional understanding. This article presents a review of contemporary subsidence research to reveal the most influential of the processes at the Bamkikaiy subsidence zone. The objective is to through light into the origin of the subsidence accompanied by landslides often misconstrued and giving a supernatural origin to this phenomenon by the local population. At the end of the research the population will understand the natural geological link to the subsidence and dispel mystical connotations hitherto associated.
Keywords:Subsidence, mass movement, Kaolinite, Clay minerals, hydrolysis, feldspars.
