Microfacies of aquitanian–burdigalian (early miocene) deposits in east-southeast of Mollababa Village (Mus)

This study aims to describe the microfacies and depositional environments of the Aquitanian - Burdigalian (early Miocene) aged carbonate and clastic rocks of Mollababa and Aktaş formation in the east-southeast of Mollababa village (SE Muş). In the study area, Mollababa formation ( Aquitanian) which consist of calcareous sandstone, siltstone-sandstone alternation, bioclastic limestone with abundant bentic foraminifera, and calcarenite overlies Kazanan formation (upper Oligocene) conformably. Aktaş formation (Burdigalian) which comprise calcareous sandstone, with abundant microfossil, clayey limestone and sandy limestone takes place on Mollababa formation conformably and transitive. In the study area, three stratigraphic sections were measured as MB1, MB2 and MB3. A total of 330 m thick sedimentary sequence was measured for Mollababa and Aktaş formations in these sections. A total of 110 rock and washing samples were collected from these sequences. As a result of the micropaleontological and sedimentological studies of the thin sections of these samples, calcarenite with Lepidocyclina and large benthic foraminifera, packstone - grainstone with Lepidocyclina and macrofossil grains, packstone - grainstone with Operculina and Textulariidae and sandstone microfacies were described. Depositional environments of these microfacies range from reef front to open shelf environment.
