Reference Section of the Campanian Stage of the Southwestern Crimea: Problems of Substage Subdivision and Global Correlation
Abstract—
Stratigraphy of Campanian deposits in the stratotype of the Kudrinskaya Formation in the Southwestern Crimea is revised. For the first time, integrated sedimentological, biostratigraphic (ichnofossils, cephalopods, inoceramids, foraminifers, dinocysts, nannoplankton, gilianelles), isotope-geochemical, paleo- and petromagnetic characteristics of the section were obtained. The boundary of the lower and upper Campanian is substantiated and confirmed by U–Pb dating of zircons from the well-known bentonite (kil) clay bed in the interval of 77–80 Ma. It is proposed to accept the Campanian Substage boundary of the General Stratigraphic Chart (for bipartite stage subdivision) at the top of the Chron C33r, located near the δ13C isotopic excursion “MCaE” – Mid-Campanian Event, near the first occurrence of the benthic foraminifer Brotzenella monterelensis and a number of other traditional biomarkers.
期刊介绍：
Stratigraphy and Geological Correlation is the only journal that provides comprehensive coverage of the fundamental and applied aspects of stratigraphy and the correlation of geologic events and processes in time and space. Articles are based on the results of multidisciplinary studies and are for researchers, university professors, students, and geologists interested in stratigraphy and the chronological features of the world’s geological record.
