Intrusive rocks of Devonian age in the studied area in Central Kazakhstan are represented by three intrusive complexes: the Early Devonian Karamendy, the Middle Devonian Terekty, and the Late Devonian Kokkuduktobe. Based on the results of studying the composition, absolute age, and evolution of the massifs of these intrusive complexes, their actual belonging to a single Early Devonian complex was established. Their geological evolution was clarified to correct the stratigraphic layout of the region. The dating of zircon grains was carried out. The work was executed on the basis of original, reliable determinations of the absolute age and the data of the petrographic composition. The obtained data made it possible to revise the historically established ideas about the absolute age of these intrusive complexes, which is of fundamental importance for the purposes of regional geological studies, geological mapping, and determining the age of metallogenic processes. Our results can serve as a good marker when developing legends for a series of geological maps currently being developed.
