Key words: Eastern Siberia, preobrazhensky horizon, Verkhnechonskoye field, lithology of the carbonate rocks, facies, secondary transformations, unconformities.
The basic lithogenetic types of rocks and facies of the Preobrazhensky productive horizon and deposits containing it are established on the basis of detailed studying of a core of new well on the Verkhnechonskoye field. Upper Nepsky and lower Danilovsky unconformity are confirmed. The unconformity in the lower part of the Preobrazhensky horizon is disclosed for the first time.
