Metallic element geochemistry of including organic matter rich lithologies of Malatya and Keban metamorphics

Metallic Element Geochemistry Of Including Organic Matter Rich Lithologies OfMalatya And Keban MetamorphicsOrganic-rich sedimentary rocks (black shale, bituminous shale, organic rich carbonates), and meta-sedimentary formations (black schits) have significant amounts of S, Ba, Fe, B, V, U and, trace elements; Ge, As, Bi, Cd, Pb, Mo, PGE, Zn, Au The organicrich lithologies is considered to form during the Oceanic Anoxic Events (OAE) and metal content of these lithologies can be economical.In this study, geochemistry of organic-rich lithologies of Permian Malatya and Keban Metamorphics are investigated. Malatya and Keban Metamorphics are composed of metacarbonate and metapelites, organic-rich shales and limestones. The organic-rich lithologies of Malatya and Keban metamorphics have higher trace element, metallic element and REE content than that of crustal average. There is a positive correlation between TOC- ?ME and ?REE-?ME. The presence of organic matter and framboidal pyrite, positive Ce and negative Eu anomalies indicate that organic-rich lithologies formed in anoxic sedimentary basins.Key Words: Malatya- Keban Metamorphics, Organic-rich, Oceanic Anoxic Events (OAEs), Geochemistry, Metallic Element, REE
