Abstract

Radiolarians and planktonic foraminifera are documented in the chert and limestone alternations in the Yigitler section from the Circum Troodos Massif Sedimentary Succession in northern Cyprus. Based on the stratigraphic ranges of radiolarians, the examined samples from the Middle Lefkara Formation can be assigned to six biozones: Bekoma bidartensis (RP7), Buryella clinata (RP8), Phormocyrtis striata striata (RP9), Theocotyle cryptocephala (RP10), Dictyoprora mongolfieri (RP11) and Thyrsocyrtis (Pentalacorys) triacantha (RP12) zones. The planktonic foraminifera recovered from the examined samples are assigned to Morozovella velascoensis IZ (P5), Morozovella subbotinae PRZ (P6), Morozovella aragonensis/Morozovella formosa formosa CRZ (P7), Morozovella aragonensis PRZ (P8) and Acarinina pentacamerata PRZ (P9) zones. These zonal assignments indicate a Late Paleocene to early Middle Eocene age for the Middle Lefkara Formation.
