Geochemical & palaeontological Study of Gulneri Formation(upper cretaceous) NE-Iraq
Gulneri formation in it's type locality (Dokan Dam), had been studied geochemically & palaeontologically. The trace elements (Mn, Ni, Cr, Sr, Rb) in addition to K2O(IR.)& (L.O.I) were documented. The genus & species of planktonic foraminifera has been identified, where the index spe...

| Summary: | Gulneri formation in it's type locality (Dokan Dam), had been studied geochemically & palaeontologically. The trace elements (Mn, Ni, Cr, Sr, Rb) in addition to K2O(IR.)& (L.O.I) were documented. The genus & species of planktonic foraminifera has been identified, where the index species used to determine the age of the formation (Lower Touronian). The study deduced form the behavior & distribution of geochemical elements in addition to the metamorphic processes acting on glauconite mineral which leads to formation of Byrite mineral and the presence of bio-assemblages in the Black shale, that Gulneri formation were deposited in deep marine ecology away from the shoreline which influenced by oxygen deficiency (Euxenic environment |
