On possibility of using the global Permian stage scale in the Tethyan region

A possibility of using the Permian global chronostratigraphic scale in the Tethyan legion is estimated in this work. Permian successions in this regio n show that the proposed subdivision of the Permian System into the Cisural ian, Guadalupian, and Lopingian series is efficient when it is definitely p roved that the lower boundary of the Guadalupian Series corresponds to the base of the Kubergandian Stage of the Tethyan scale. This problem is, howev er, unsolved so far. The Asselian. Sakmarian, and Artinskian stages of the Cisuralian Series correspond to the Asselian, Sakmarian, and Yakhtashian st ages of the Tethyan scale. The correlation between the Kungurian and Bolori an stages can be taken for testified, when the exact position of the lower boundary of the Guadalupian Series is established. The conodont biostratigr aphy used to discriminate the Roadian, Wordian, and Capitanian stages of th e Guadalupian Series is inappropriate for the Tethyan region. The Wuchaping ian and Changhsingian stages of the Lopingian Series correspond to the Dzhu lfian (sensu stricto) and Dorashamian stages of the Tethyan scale.
