Age

I.A. Kim et al. (1990) considered this suite as the Kultarminskaya suite and attributed it to the Upper Devonian, Famennian. V.P. Vashchenko et al. (1992) renamed it as the Egarbelitau suite of the Upper Devonian. V.S. Korsakov et al. (1993) - to the Upper Devonian. I.A. Kim et al. (1995) named it the Kultarminskaya suite in the span of the upper part of the Upper Devonian, Famennian in Egarbelitau + Frasnian and Tournaisian deposits in Balyklitau. On the State Geological Map-500 of Uzbekistan, it is dated to the Late Devonian-Early Carboniferous. (460).
