The article presents a step-by-step historical review of the stratigraphic study of the pre-Mesozoic deposits of the Zirabulak
Mountains, starting from the 40s of the last century, with an analysis of previously created stratigraphic schemes, as well as
belonging to various structural-formational zones (SFZ). The results of the generalization showed that so far many suites
(Karachakuduk, Bulyamush, Katarmai, etc.) do not have a reliable age, volume and thickness. Analysis of the SFZ showed that
the same formations belong to different SFZ.
