The youngest and more than 1,000 m thick sequence of the Central and Western Bohemian Basins is represented by the Líně Formation. There are up to 10 often fossiliferous lacustrine horizons and the Horizon of Conglomerates with carbonate pebbles. Comparison of interpreted facies with ichnologic and paleontologic data enable to assign the corresponding paleoenvironments and paleoclimates near the Carboniferous/Permian boundary. The paleocurrent, facies, and fossil communities analyses can clarify paleogeographic situation of the tropical zone of Pangea. Provenance of the unique marine carbonate Paleozoic pebbles will be solved with help of micropaleontology. Large scale tectonic elements will be studied with help of GIS analysis of remote sensing data and digital elevation model. The Ichnofabric Index will be determined in continuous profiles and drill cores. The vertebrate assemblages (obtained also by chemical way) integrated with correlation of well logs can solve stratigraphy.
