Abstract: In this study, it is aimed to reveal the foraminiferal content and microfacies properties of the the UpperTriassic carbonates, cover units of the Bitlis massif exposed in the vicinity of the Çakmakkaya village (Palu, Elazığ).Stratigraphically significant foraminiferal species characterizing Triassic have been recorded throughout themeasured section. Triasina hantkeni, the most common taxa documented in the studied sequence, is considered as azonal marker for Late Triassic. Besides the zonal marker species, the section includes Aulotortus sinuosus, Aulotortusfriedli, Involutina sp., Galeanella? sp., Duostomina sp., Glomospira sp., Glomospirella sp., Duotaxis birmanica,Siphovalvulina sp., and Reophax sp. foraminiferal assemblages. On the basis of the determined foraminiferal taxa,Triasina hantkeni zone is defined within the studied succession and a late Norian-Rhaetian age is attributed. Inaddition to foraminiferal assemblages, megalodontids, algae, gastrapods and corals are also present within thelimestone units. Three facies types, mudstone, wackestone-packstone, pelloidal bioclastic packstone-grainstone,were described based on microfacies studies to determine the depositional environments of the Upper Triassiccarbonates exposed in the region. The described microfacies types suggest that the depositional environment was alagoon and shallow marine platform environments.
