“…This study is a preliminary research work for future projects to understand the earth history in the entire Mamfe Sedimentary Basin, considered to be the least studied basin in the west and central African region. [19,29,30]. The locale presence of evaporites (dominated by halite) suggests a late Aptian-early Albian marine ingression from the Douala Basin [23].…”

Zircon crystals from two basement rocks (granitic pegmatite and mica-schist) in the Mamfe Basin were studied to provide petrogenetic and geochronologic constraints, therefore were characterized and dated by LA-Q-ICP-MS analytical techniques, after their internal textural features were determined.Zircon crystals with oscillatory zoning from the granitic pegmatite exceed 200 µm are mainly euhedral to prismatic. The U (≤169 ppm), Th (≤240 ppm), and Th/U (0.6-1.7) are within the range of zircon crystallized in crustal magmatic environment. Zircon crystals from the mica-schist are ˂100 to ˃200 µm in size, have magmatic (e.g., euhedral prismatic with oscillatory zone) and metamorphic (e.g., form round soccer ball, sub-hedral with overgrowth) features. The U (23-687 ppm), Th

“…The main sedimentary basins in Cameroon are the Mamfe, the Rio del Rey and the Douala/Kribi-Campo Basins. The description of the geology of these basins are found in [23][24][25]. The Cameroon Volcanic Line (CVL) is the main Tertiary feature in Cameroon, made up of volcanic massifs (Pagalu, Bioko, Sao Tome and Principe, Mounts Cameroon, Rumpi, Manenguba, Bamboutos, Mbam, and Oku) [26][27][28].…”

Abstract:The geochemical characteristics of selected kaolins from Cameroon and Nigeria are presented, with an attempt to elucidate on their possible industrial applications by comparing them to world-known kaolin deposits. Major oxides concentrations were subjected to factor analyses in interpreting their relationships. Geochemical indices, including chemical index of alteration (CIA), chemical index of weathering (CIW) and the index of compositional variability (ICV) were computed and plotted on binary and ternary diagrams to determine the intensity of weathering of the kaolins and discriminate their different source rock types. Kaolinite was the major phase, followed by quartz, illite and goethite as minor phases. Minerals in trace phases included smectite, anatase, muscovite, gibbsite, microcline, palygorskite and calcite. Mean abundances of major oxides in wt% were: SiO 2 (56.96)>Al 2 O 3 (24.09)>Fe 2 O 3 (3.78)>TiO 2 (1.53)> K 2 O (1.26)> MgO (0.27)>CaO (0.20)>Na 2 O (0.17)>P 2 O 5 (0.05)>MnO (0.04). The CIW versus CIA and ICV versus CIA plots showed that most of the kaolins clearly depicted extreme silicate weathering. The current applications of kaolins from Cameroon and Nigeria include ceramics and manufacturing of bricks and tiles. Low MgO, CaO, Na 2 O, K 2 O and TiO 2 further position the kaolins for pharmaceutics, cosmetics, rubber and plastic applications. Thus, the studied kaolins have the potential to contribute to improved economic development of these countries.

“…Main peaks with carbon numbers greater than nC 20 reflect the significant incorporation of higher plant wax and some fungi, whereas those with lower carbon numbers indicate major inputs from microbial activity (algae and bacteria -nC 17 , nC 18 ) or petroleum (diesel exhaust -nC 20 , nC 21 ). LMW/HMW ratio in n-alkanes in sediments is used to distinguish macrophytes from terrestrial plants [10].…”
