ABSTRACT
The Serpukhovian sections in the Big Karatau Mountains of Kazakhstan are well exposed and contain an excellent fossil record; consequently, they can be used as reference sections for the Visean-Serpukhovian boundary [Zhaimina, 2006]. The best-studied boundary successions in the northwestern part of the Big Karatau in the Ushozen sections. In the Ushozen section contain Foraminifers, Brachiopods, Crinoids, and Algae. The stratigraphic scheme for the Carboniferous Systems used in Kazakhstan is similar to the General Stratigraphic Scheme adopted for Russia and the countries of the former Soviet Union in 1992, but without the subsequent changes adopted for Russia in 1997. During the 1970s, the Carboniferous scheme was elaborated on in the USSR, and was adopted in 1986 by the Stratigraphic Commission of the USSR. Since then, changes have not been introduced in the scheme as used in Kazakhstan. In 1991, a succession of regional substages was adopted for the Regional Stratigraphic Scheme employed in Kazakhstan but that convention requires revision and the situation has initiated the reexamination of the position of the Viséan-Serpukhovian boundary and other Carboniferous boundaries in Kazakhstan.

Keywords: Big Karatau Mountains, Ushozen section, Viséan-Serpukhovian stage, Foraminifera
