In Ordovician times the Łysogóry Region (northern Holy Cross Mts.) was located in the marginal part of Baltica, thus, the sea-level history reconstructed for this palaeocontinent appears to be a good background for discussing relationships between sea-level changes and the studied sedimentary record. However, some stratigraphic gaps, e.g. in the Lower and Middle Ordovician parts of the considered succession are probably due to regional tectonic activity. The upper Middle and Upper Ordovician sedimentary facies of the Łysogóry Region show good correlation with the Late Llanvirn-Caradoc Highstand Interval followed by the Ashgill Lowstand Interval in Baltica (Nielsen, 2004). The most conspicuous facies changes in the Ordovician of the considered region seem to be coeval with 3rd order eustatic events recognized on the sea-level curve from Baltoscandia.
