Correlation of the Middle-Upper Devonian deposits of the North of Kuzbas and the Tom-Kolyvan region

Issues of correlation of the Middle-Upper Devonian sediments of the northern part of the Kuznetsky marginal deflection and the neighbouring Tom-Kolyvan folded zone are considered. The lateral range of suites of the Givetian include as follows: the Barzasskaya and the Dmitrievsko-Pereboyskaya suites (marginal lake); the Yayskaya and the Izylinskaya suites (coastal shelf), the Mazalovsko-Kitatskaya suite, the Askold layers (remote shelf). Facial suites of the Lower Frasnian are as follows: the Yaya-Petropavlovskaya (coastal shelf), the Strelninskaya, the Pozharischevskaya, the Vassinskaya (remote shelf). On the boundary between the Lower and the Upper Frasnian in the Kuznetsk deflection part bordering Alatau there is a proluvial debris cone (the Sergievskaya suite). The Upper Frasnian includes the Kelbesskaya (shelf), the Solominskaya, the Shubkinskaya (remote shelf), the lower part of the Pa-chinskaya (the most remote part of shelf) suites. On the shelf rises reef arrays are formed. The maximum sea concave is coincided with the border of the Frasnian and the Famennian (the Upper Kellwasser event). The Lower Famennian layers are as follows: green-gray calcareous sandstones in the part near the Alatau border (coastal shelf), the Kosoutesovskiye layers and the Mitikhinskaya suite (shelf), the upper part of the Pachinskaya suite (remote shelf). The Middle Famennian includes the Podoninskaya suite (coastal accumulative plain), the Yurginskaya suite (coastal shelf). The Late Famennian includs the Salamatovskaya (remote shelf), the Topkinskaya and the lower part of the Abyshevskaya suite (shelf), red detritic limestones near the Alatau border (coastal shelf). Distinct stratigraphic scheme is to be developed for the southern part of the Kuznetsk deflection with predominantly continental type of sedimentation.
