Key words: wells; Carbonate deposits; microbial Limestones; Detrital-algae; Complex of organic remains; Micrite Walsoort domes.
The article is devoted to a description of the Core Material from the wells of the Late Paleozoic reefogenic formations of the Volgograd Trans-Volga region. Sections of wells 1, 2 Novo-Dmitrievskiy, drilled in 2014-2016, have revealed productive Famennian-Turney organogenic structures (Walsort facies). The main stages of the unique reef formations-the Walsoort facies-are singled out. For the first time in the history of the region in the reef facies of roofing layers of the Famennian stage of the Upper Devonian traced deposits of an additional Zygansk horizon, which was not traced in layered sections. Complexes of sediments on real wells are given.
