Budowa geologiczna rejonu Sucha Beskidzka - Świnna Poręba (polskie Karpaty fliszowe)
(Wydawnictwa AGH, 2006) Cieszkowski, Marek; Golonka, Jan; Waśkowska, Anna; Chrustek, Monika
Upper Cretaceous and Paleogene rocks of the Silesian and Magura Nappes build up the complex structure of the investigated area, which is stretching along the Skawa River valley between Sucha Beskidzka and Świnna Poręba. Middle and Upper Godula Beds, Istebna Beds, Eocene red shales and Ciężkowice Sandstone as well as Hieroglyphic, Menilite and Krosno Beds form the Silesian Succession. The debris-flow deposits with exotic rocks pebbles and large olistolites were observed within the Krosno Beds. The sedimentary succession is typical for the Siary sub-unit from the Magura Nappe. The present authors proposed the formal lithostratigraphic names for this unit. According to this formalization the following lithostratigraphic units have been distinguished within the Siary succession: Jaworzynka Formation (Ropianka Beds) with Gołynia Shale member and Mutne Sandstone Member within the Paleocene part of profile, Łabowa Formation with the Żurawnica Sandstone Member, the Skawce Sandstone Member, Beloveza Formation, and Maków Beskid Formation with Zembrzyce Shale Member, Wątkowa Sandstone Member and Budzów Shale Member. The Silesian and Magura Nappes rocks are strongly folded, within the Magura Nappes several scales and longitudinal shear zones have been distinguished. The formations of both units are cut by the transversal fault systems of The Magura Nappe has the independent fault systems, some of its dislocations have been acquired, however, from the Silesian Nappe.

Lithofacies and depositional environments of the Paleogene/Neogene sediments in the Hoanh Bo Basin (Quang Ninh province, NE Vietnam)
(Wydawnictwa AGH, 2015) Tha, Hoang Van; Wysocka, Anna; Pha, Phan Dong; Nguyẽ̂n, Quó̂c Cường; Ziółkowski, Piotr
The Hoanh Bo Basin is a multiple period formed basin which is associated with the tectonic mechanism due to the activity of the Chi Linh-Hon Gai and Trung Luong Faults during the late Paleogene – early Neogene time. The basin is filled with continental sediments, comprising mainly polymictic conglomerates, sandstones, siltstones, claystones and shales. Coarser-grained polymictic deposits predominate along the northern and western margins of the basin, while different types of siltstones, claystones, even sandstones occur in its center, as well as along its southern and eastern parts toward the Ha Long Bay. The source rocks for sedimentary materials are mainly originated from rocks of the Hon Gai and Ha Coi Formations. Based on the dominant grain-size class, texture, stratification, degree of clast rounding and sorting, 17 lithofacies were determined in the Hoanh Bo Basin infill. The basin is filled by gravelly, sandy and fine-grained lithofacies just covers a modest area but it represents a full of succession of 4 depositional systems including alluvial fan, fluvial, deltaic and lacustrine environments. Alluvial fan and fluvial environments are characterized by an assemblage of lithofacies such as sand- and mud-supported disorganized breccias (Gb), clast- to sand-supported conglomerates (Gmm), clast-supported inverse-graded conglomerates (Gig), planar-cross-bedded conglomerates (Gp), trough cross-bedded conglomerates (Gt), horizontally stratified conglomerates (Gh), planar cross-bedded sandstones (Sp), trough cross-bedded sandstones (St), ripple cross-laminated sandstones (Sr), horizontally bedded sandstones (Sh), massive sandstones (Sm), massive mudstones, siltstones (Fsm), laminated siltstones and mudstones (Fl), massive claystones (Fm) and coaly lithofacies (C), the deltaic assemblage is dominated by planar-cross-bedded conglomerates (Gp), horizontally stratified conglomerates (Gh), planar cross-bedded sandstones (Sp), horizontally bedded sandstones (Sh), low-angle cross-bedded sandstones (Sl), while the lacustrine assemblage consists of ripple cross-laminated sandstones (Sr), horizontally bedded sandstones (Sh), normally graded sandstones (Sng), massive mudstones, siltstones (Fsm), laminated siltstones and mudstones (Fl), massive claystones (Fm) and coaly lithofacies (C).

Stratygrafia polskich Karpat fliszowych pomiędzy Bielskiem-Białą a Nowym Targiem
(Wydawnictwa AGH, 2007) Golonka, Jan; Waśkowska, Anna
Jurassic, Cretaceous, Paleogene, and Neogene allochtonous rocks of the Outer Carpathians build up the complex area between Bielsko-Biała and Nowy Targ. These deposits belong recently to the Magura, Fore-Magura, Silesian, Sub-Silesian and Skole Nappes. The present authors provided the systematic arrangement of the lithostratigraphic units according to their occurrence within the original basins and other sedimentary areas. The Magura Basin was formed in the Middle Jurassic. The deep--water sedimentation of radiolarites and carbonates dominated at the beginning, since the Late Cretaceous the flysch sedimentation prevailed. The proto-Silesian Basin developed during Late Jurassic and Early Cretaceous times with the syn-rift and post-rift formations. The Silesian, Fore-Magura, Skole Basins formed during Late Cretaceous. Fore-Silesian sedimentary area included the western end of the Sub-Silesian Ridge and slopes of the Silesian and Skole Basins. The western end of the Skole Basin is located within the investigated area. The slope deposits of the Sub-Silesian type and separated basinal flysch facies occurred there. The basins existed during Late Eocene to Early Miocene times: the remnant piggy-back Magura Basin and, in the northern part of the accretionary prism the Krosno Basin with Menilite and Krosno Formations.

Węgiel we fliszu podhalańskim wschodniej części Podhala

The Podhale Basin is a region in Southern Poland, in position between Pieniny Klippen Belt and Tatra Mts. It is filled up with flysh sediments of Paleogene. Typical component of flysh is coalified organic matter. It is in disseminated and accumulated form ( coal laminae to 2,0cm). Rank of the matter is typical for bituminous coal. Coaly beds are the focuses of vitrinite manly composed of colotelinite, while dispersed organic matter is represented by tiny pieces of vitrodetrinite, fusinite and inertodetrynite. It is regional variability point on significantly increasing rank of organic matter from north-western parts of Podhale Basin to South-eastern ones.The variability reflects faulting tectonics of flysh sediments.
