Farg’ona botig’i hududida tarqalgan paleogen davri yotqiziqlarining tabiiy ochilmalarinitavsiliy litologik tadqiqetich natijasida formatsiyaichi tanaffuslari va yuvilichlari aniqlangan. Ularning paleogen paleoxavzasi hosil qilganqatlamlar orasida namoyon bo’lich xarakteri va neft konlarini qidirichdagi amaliy ahamiyati yoritilgan.
Tayanch iboralar: formatsiyaichi tanaffuslar, suv osti yuvilichlari, suv tubi oqimlari, paleogen davri yotqiziqlari,cho’kindi yig’ilishi, paleoxavza,litologik tarkib, neft tutgich, invertsiya, paleozoy poydevori.
Detailed and versatile lithological studies of natural outcrops of the Paleogene deposits of the Fergana depressionhave revealed a number of intraformational breaks and erosion. Their character is shown to be confined to certainstratigraphic horizons of Paleogene deposits and is of practical importance in prospecting and exploration of oildeposits.
Key words: intraformational breaks, underwater erosion, Paleogene deposits, sludging, paleobasin, lithologicalcomposition, oil trap, inversion, paleozoic foundation.
