Description of primary interest:
The profile exposed in Głębieniec Stream Valley presents a sequence of flysch deposits of Albian, Cenomanian and Turonian age. The oldest strata of log in Głębieniec Stream valley are the Middle Lgota Beds. They are developed as fine-bedded, laminated quartzitic sandstones intercalating by black, siliceous shales. The Middle Lgota Beds are overlaying by complex composed of siliceous marls, variegated siliceous shales as well as by thick-bedded sandstones of Godula type. The mentioned sequence is developed only in the northern part of Beskid Mały. Siliceous marls are developed as yellow-weathering marlstones or even flysch limestones abundant with trace fossils. A grey, fine-bedded carbonate sandstones and shales complete this sequence. Siliceous marls forming three intercalations in the described series. Variegated shales contain both red and green non-carbonate siliceous shales without sandstones. They contain a single layer of radiolarites. This unit is represented in two horizons but only a lower one is well visible in Głębieniec Stream Valley. The next components of this profile are thick-bedded sandstones and conglomerates with glauconite and exotics of crystalline and sedimentary rocks. They are corresponds with the Lowermost part of the Godula Beds. These sandstones forming two horizons. Glauconite, fine-bedded sandstones and black shales belonging to the Lower Godula Beds complete this profile. The whole described sequence is very gently folded.
