Systematics and Biostratigraphy of Foraminifera in Albian to Lower Cenomanian Deposits at Kerch Section (Southwest Qayen)

In this research systematics and biostratigraphy of the Cretaceous deposits foraminifera in Kerch section, southwestern Qayen, in the eastern margin of the Lut Block, were studied in detail. This section with 260 meters thickness, mainly formed by gray to cream color marl and shale, marly limestone and limestone laid on a light-colored limestone bed at the base. Seventeen genera and twenty two species from benthic and planktonic foraminifera were recognized. Four biozones including Microhedbergella rischi Interval Zone, Ticinella praeticinensis Interval Zone, Ticinella raynaudi Interval Zone, Lenticulina subangulata -Lenticulina macrodisca assemblage zone were also determined. Based on identified foraminifera an Albian to Early Cenomanian age is suggested for the Kerch section.
