Atlas of Foraminifera of the Carboniferous and Permian (Cisuralian) of Uzbekistan and Adjacent Regions, Tien Shan

About this book

Language: English

The Atlas summarizes known and new data of the Carboniferous and Lower Permian Foraminifera of Uzbekistan and adjacent regions. The Atlas supplemented and corrected of the assemblages of 27 Foraminiferal Zones and regional substages of the Carboniferous (beginning with Serpukhovian Stage) and lower part of the Permian, questions of the boundary between Carboniferous and Permian systems and also mid-Carboniferous boundary. Descriptions of 109 fusulinoids species are presented. The Atlas includes 89 paleontological plates and shows the foraminiferal assemblages, including fusulinoids, in the stratigraphic succession from the Serpukhovian Stage of the Lower Carboniferous up to and including the Sakmarian Stage of the Lower Permian of the Middle and Southern Tien Shan in Central Asia.

Atlas of Foraminifera of the Carboniferous and Permian (Cisuralian) of Uzbekistan and adjacent regions, Tien Shan is of the interest and importance to paleontologists, stratigraphers and geologists, and who study the Carboniferous and Lower Permian deposits Uzbekistan and Tien Shan.
