ELEMENTARY STRATIGRAPHIC UNITS

Abstract

It has been established that every tenth bed of the Upper Cretaceous-Danian flysch deposits can be traced along the southern slope of the Greater Caucasus over a distance of 1035 km. This allowed 196 synchronous markers to be established in this region. Their synchronism is based on a relative number of cyclites and confirmed by paleontologic data. The formation time of one global stratigraphic unit is assumed to average 22 ± 9 k.y.
