The Upper cretaceous calciclastic submarine fan deposits in the Eastern Pontides, NE Turkey: facies architecture and controlling factors
The Tonya Formation, which represents the uppermost part of the Mesozoic sequence in the Eastern Pontides, consists of calciturbidites in Trabzon and its surrounding region. Two stratigraphic sections of the unit were measured in the Hacımehmet and Gürbulak areas to decipher the distribution of rock...
