FORAMINIFERAL TIMING OF CARBONATE DEPOSITION ON THE LATE DEVONIAN (FAMENNIAN)-MIDDLE PENNSYLVANIAN (BASHKIRIAN) TENGIZ PLATFORM, KAZAKHSTAN
Calcareous foraminifers provide a time-stratigraphic framework to chronicle the development of the Tengiz carbonate platform that thrived from the latest Devonian (late Famennian) into the Middle Pennsylvanian (late Bashkirian).Correlative Flags zones, based on documented foraminiferal assemblages and expressed primarily in terms of Russian horizon
