Özet

The Yüksekova Complex is one of the parts of oceanic crust representing the Bitlis-
Zagros suture zone in the eastern Turkey. The volcanosedimentary rocks of the unit, which is
widely exposed around the Elazığ (E-NE Turkey) province are located in the Seki-Hacıhasan
district (E Elazığ) and Asker Mountains (NE of Elazığ). In this area, the planktonic
foraminifera bearing pink-red micritic limestones and related volcanogenic rocks were
examined and aged. The volcanogenic rocks related to the micritic limestones are mainly
spilitic and pillow shaped basalts. The volcanogenic rocks contain mainly of plagioclase ±
pyroxene ± partly olivine set in amygdaloidal, intersertal, hyalo-microlitic porphyric textures.
The sediments consist mainly of thin- to- medium- bedded muddy limestones. The pelagic red
limestones are represented mostly by biomicrite and contain a large quantity of planktonic
foraminifera and slight amount of thin shelled bivalve fragments, radiolaria, and echinoderm
fragments. The planktonic foraminifera are composed mainly of Globotruncana arca, G.
gagnebini, G. lapparenti, G. cf. falsostuarti, Globotruncanita stuarti, Gt. stuartiformis, Gt.
conica, Globotruncanella citae and Rosita fornicata scattered into a micritic matrix. Small
amounts of silt and sandsized quartz grains are also observed in some thin sections.
Accordingly, based on planktonic foraminifera bearing micritic limestones, the age of the
Yüksekova Complex is proposed Late Campanian-Late Maastrichtian. Thus, the Late
Campanian-Late Maastrichtian aged red pelagic limestones of the Yüksekova Complex were
deposited in the deeper parts of the Late Cretaceous Ocean, probably a deep shelf edge.
