Southern Urals. Deep water successions of the Carboniferous and Permian. A Field Guidebook of XVIII International Congress on Carboniferous and Permian / Южный Урал. Глубоководные последовательности каменноугольных и пермских отложений

This guidebook describes the sections of the Upper Carboniferous and Lower Permian of the Preuralian Foredeep, and gives lithological and paleontological characteristics of the deposits. The guidebook is intended for geologist and paleontologist who study Carboniferous and Permian stratigraphy and paleontology, and for students and teachers of fieldwork techniques.The Guidebook «Southern Urals. Deep water successions of the Carboniferous and Permian» is devoted to the description of the sections of Mechetlino, Dalnyi Tyulkas, Usolka and the Sterlitamak Shikhans. The sections occur in relatively deeper-water portions of the Preuralian Foredeep.
In the Mechetlino section on the right bank of the Yuryuzan River, carbonate- siliciclastic deposits of the Kungurian-Artinskian boundary are exposed. This section contains fusulinids, ammonoids, conodonts and presumably some layers of volcanic tuffs. Numerous fusulinids, ostracods, calcareous algae, conodonts and ammonoids are found here. 
The Mechetlino section is a candidate for the Global Section Stratotype and Point (GSSP) for the base of the Global Kungurian Stage of the International Stratigraphic Time Scale.
The Usolka and Dal’ny Tulkas sections are located on the right bank of the Usolka River at the northeastern margin of the city of Krasnousolsk, in the Republic of Bashkortostan, Russia. The sections are represented by continuous, thick marine mixed carbonate-siliciclastic deposits of Upper Carboniferous and Lower Permian Age. The Usolka section is proposed as the Global Stratotype Section and Point (GSSP) for the lower boundary of the Gzhelian and Sakmarian Stage. The Dal’ny Tulkas section is proposed as GSSP for the lower boundary of the Artinskian Stage for the International Geochronological Scale.

The Sterlitamak Shikhans are located near the town of Sterlitamak and are mostly composed of carbonate rocks of the Asselian and Sakmarian Stages. Reefs are located on the border of the Russian plate and the Ural trough. During the tour three of these reefs will be shown: Tra-Tau, Shakh-Tau and Yurack-Tau.<....>
