Abstract: The early Devonian transgressive deposits at Chęciny in the Holy Cross Mts, which rest on a weathered surface of Lower Cambrian claystones, are represented by diverse terrigenous looks containing scarce marine fossils in their higher part. The lower part represents a laical waste, redeposited under continental conditions. The thin development of the transgressive terrigenous sequence (8 m) points to slow subsidence and a rapid advance of marine conditions. These deposits are overlain by carbonate-terrigenous (chiefly dolomitic) rocks containing a diversified open-marine fauna. The paleogeography of the early Devonian is discussed. Evidence is presented for a swell, trending E-W, in the southern part of the Holy Cross area; also for the presence of an epicontinental basin filled with Lower Devonian deposits over 1 km thick in the northern periphery of that area. It is concluded that there is little evidence for the concept of Caledonian geosyncline in southern Central Poland.
