Biostratigraphy of the Chergak supra-horizon of Tuva
Authors:
Abstract
In geological studies of Tuva and adjacent areas use the stratigraphic scheme adopted by the Second Meeting on the development of stratigraphic schemes of Central Siberia in 1964 and approved by the Interdepartmental Stratigraphic Committee of the USSR. According to this scheme, the Silurian of Tuva is represented by two horizons: the lower - Chergakian and the upper - Khondergean ...
