Geological and Geomorphologic Conditions and Traces of Prehistoric and Historic Human Settlements in the Vicinity of Ulów (Roztocze Region, Southeastern Poland)

Abstract

Abstract The paper presents determinants of location of the multicultural complex of archaeological sites in the vicinity of Ulów, in the Central Roztocze upland region in south-eastern Poland. Archaeological research revealed that in the area assumed to be devoid of settlements, the settlements of prehistoric and historical communities functioned from the Palaeolithic to modern times. The region was also subjected to environmental examination. Location of sites was analysed, taking into account a convenience of communication in a regional scale and local environmental conditions. Analysis of hydrogeological, geomorphological and soil conditions was carried out, taking into account water supply, communication and the farming development. In-depth analysis included micromorphological DTM (Digital Terrain Model) and geological and soil probing. The area was found to be located on the crossing of prehistoric communication routes the course of which depended on the variability of the physiographic parameters of regions. The functioning of new cultures in the same place resulted from specific local conditions such as: easily arable soils, favourable microclimate, and particularly access to water. The presence of a source of water in a plateau area is determined tectonically (strike-slip fault), lithologically (impermeable marl horizon), and geomorphologically (dissection of the aquifer by an erosion-denudation valley).
