Journal: Stratigraphy and Geological Correlation
Year: 2022

Correlation of the Valanginian sections in Southwestern and Central Crimea was refined on the basis of the methods of cyclo- and sequence stratigraphy. Using the Sr-isotope stratigraphy (SIS) method, the age of the carbonate rocks of the Zelenogorskoe Series in the Beshterek River valley in Central Crimea was determined as early Valanginian (87Sr/86Sr in the range of 0.707343–0.707355). Four lithological complexes have been identified by the facies analysis of sedimentary rocks: deep-water clay,
