Líně Formation is the youngest basin fill unit of the Upper Palaeozoic Central and Western Bohemian basins. Deposits of the Líně Formation were being laid down in Stephanian C time, after an unconformity between Stephanian B and C. The deposits of Líně Formation are continental red beds usually dominated by mudstones with less common appearance of sandstones and conglomerates, originated mostly as fluvial deposits. Lacustrine deposition originated in deposition of less frequented fossiliferous claystones, carbonates of variegated and grey colors, coal occur occasionaly. The study area was at Kladno part of the Kladno- Rakovník Basin, Roudnice part and west half of Mšeno part of Mšeno-Roudnice Basin. Seismic sections were interpreted and correlations of boreholes based on lithology, gama and resistivity ray were made. Scientific borehole K-1 (Klobuky) drilled in 2009 showing 30 m long succession of Klobuky Horizon was described and interpreted too. The interpretations of approximately N-S oriented seismic sections show depressions on the base of Líně Formation. This morphology seems to affect direction and area of sediment deposition at the beginning of Líně Formation sedimentation in the study area. Well-log correlations show main areas of sediment deposition in the west and north of Roudnice part...
