%X The late Paleozoic bivalves of brackish water and fresh water, often referred to as "non marine facies", were widely distributed in the late Paleozoic due to the widespread development of the special facies environment related to transgression and regression in the vast region. At that time, the periodically submerged coastal plains were forming, and these plains became places of strong sedimentation and coal formation. Under unstable hydrochemical conditions, bivalve animals constitute the main part of the fauna, sometimes even the only group. They can not only inhabit the coastal environment, but also tolerate a considerable degree of desalination. They live in the residual water body inside the mainland or infiltrate into the estuarine area. Therefore, they can be used for the correlation of contemporaneous but different facies (Marine and continental) strata, which is very important for the late Paleozoic section in Siberia.In Western Europe, the late Paleozoic non marine bivalves have been successfully used for regional correlation of coal bearing sediments. The faunal zoning of coal bearing basins in England can be correlated to Belgium, France, and even the Donets Basin. For Siberia and Kazakhstan, the late Paleozoic coal bearing strata are widely developed, and a series of large coal basins have been formed, but similar section zoning has not been carried out. On the one hand, the conditions in this region, especially in remote areas (such as the northwest of the Siberian Platform and the southeast of Kazakhstan) have greater diversity in lithofacies and climate, on the other hand, the study of Late Paleozoic "non marine" bivalves in Siberia and Kazakhstan is not sufficient.Generally, the comparison of coal bearing sedimentary areas in Siberia and Kazakhstan is based on flora, and the degree of bivalves used for this purpose is far from enough. This is not only because the actual materials known so far are limited, but also because of the particularity of th
