The paper provides a description of primary geological logs, characteristics and formal lithostratigraphy of the uppermost Emsian and lower Eifelian of the Kielce Region of the Holy Cross Mts., central Poland. Nine sections of this interval, representing the whole area of the Kielce Region, and ranging between the Lower Devonian clastics of the Winna Formation and the Middle Devonian carbonates of the Kowala Formation were studied.The succession is divided into the Barania Góra Dolomite and Limestone Formation and the Wojciechowice Dolomite Formation. Six members are distinguished within the former. In the western part of the region these are (in stratigraphical order): Porzecze Claystone Member, Dębska Wola Dolomite Member, Dąbrowa Limestone Member, and Brzeziny Dolomite Member. In the eastern part, the formation is divided into the Janczyce Dolomite Member and the Jurkowice Dolomite Member. Additionally, the Wszachów Dolomite Member and Nowy Staw Dolomite Member are distinguished within the overlying Wojciechowice Formation. The thickness of the uppermost Emsian–Eifelian succession ranges from ca. 200 m in the eastern part to ca. 130 m in the western part of the Kielce Region.
