An Approach To Provenance, Tectonic And Redox Conditions Of Jurassic-Cretaceous Akkuyu Formation, Central Taurids, Turkey, Ali Sari, Derya Koca

Bulletin of the Mineral Research and Exploration

Late Jurassic-Early Cretaceous Akkuyu formation was deposited on marine carbonate platform in Central Tarurids. The organic material of the unit is composed of Type III kerogen which is woody material transported from the land. Late Jurassic- Early Cretaceous is an important period which great anoxic events in deep sea bottom occurred due to the primary organic productivity in global sea surface. Use of several trace elements values (Ni, V, U, Cr, Co, Th) revealed that Late Jurassic-Early Cretaceous Akkuyu formation shows oxic, disoxic and anoxic paleoredox conditions. In this period the primary productivity was considerably high. Examination of specimen derived …
