Black shales are highly enriched in essential elements containing critical information on metallic richness and paleoclimatic imprints during deposition. The Cretaceous period marks the age of Basin formation from which Mamfe was formed Albian to Cenomanian. purpose this study is investigate geochemical behaviour their metallogenic significance. Twenty-five representative shale samples were collected seven sites outcrops Basin. major trace composition analysed using Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) Plasma Mass (ICP-MS). In comparison with standard values for metalliferous shales, Boron (B), only few Li, Rb, Cu, Pb Zn. Aluminium module (Alm) ternary diagram plotted Al-Fe-Mn shows that all considered as terrigenous sediments 02 (08%) falling within zone sediments. characteristics inferred C-values (0.3-3.1), Sr/Cu (0.6-8.9), Sr/Ba (0.1-2.8), Rb/Sr (0.3-0.9), Fe/Mn (1.8-180), Al/Mg (0.31-31) Mg/Ca (0.05-16.4) data indicate climate existed source area weathering ranged a sub humid more ≤5% displaying arid climate.

The Cretaceous-Palaeogene intertrappean deposits of the Deccan Volcanic Province India comprise vertebrate, invertebrate and plant fossils dominantly continental realm. A 3–4 m thick shaly-sandstone lacustrine sequence Early Palaeogene (Palaeocene-Early Eocene) Bamanbor Formation, Chotila Basin (Saurashtra province, Gujarat State, western India) has yielded a collection molluscans (bivalve few gastropods) fauna. High-resolution digital photography radiography recovered bivalves allowed us to gain detailed inferences on shell morphology. In taxonomical context, we herein propose new unionid molluscan superfamily Deccanoidea nov. represented by single family Deccanoidae that includes two subfamilies, is, Deccanoinae (represented genera Deccanoida gen. [including four species: D. conrugis sp. nov., aleta costaria nov.] Bamanboria one species oblongis et Chotiloinae [represented genus Chotilia three trappeansis C. tuberculata deccanensis nov.]). Inorganic geochemistry host (unionid-yielding) lithologies reveals oxic-freshwater conditions, humid-climate moderate rainfall. data historical biogeography Indian subcontinent hosted unionids during late Cretaceous; however, presence (at family/generic level) fauna in indicates changes geographic position ecologic condition linked northward drift lava outpouring, respectively. disjunct distribution erstwhile Gondwanan continents insular interval can be explained terms both vicariance dispersal.
