Our study concerned magnetic properties of soil profiles taken from polluted regions of Eastern Ukraine around the industrial centres Krivyj Rig, Mariupol and Komsomolsk. Soils represent chernozem and podzoluvisol. The low-field magnetic susceptibility shows enhancement in the topsoil caused by contamination by coarse-grain magnetite connected with industrial pollution. Magnetic mineralogy was determined by means of thermal demagnetisation of SIRM, monitoring of susceptibility changes during warming from -196°C to room temperature and heating to 700°C, and Mössbauer analysis. Granulometry of magnetic particles was investigated by determination of hysteresis parameters, susceptibility, M s , SIRM and ARM ratios and frequency dependence of susceptibility. The chemical parameters, namely pH, organic carbon and iron content in different pedogenic and lithogenic minerals, measured for particular horizons determined pedogenic characteristic of soil profiles. Our study showed that differences in magnetic parameters of non-polluted and polluted soil profiles are not limited to the topsoil, but reach deep layers of the parent material. Industrial pollution promotes formation of the so-called “pedogenic” SP and SD particles in these layers.

The Roztochya Hills and Lublin-Lviv Upland (Volyn Upland) are the north-western spurs of the Volyn-Podil Upland. They consist of the Cretaceous, Neogene and Quaternary deposits. 39 geosites are registered here, 14 of them having the geoprotection status. In these regions more than 60% of the geosites are referred to geomorphological type of geosites. In the paper, 4 objects of geological heritage of Roztochya Hills and the Lublin-Lviv Upland (Volyn Upland) have been proposed for the draft candidate list of geosites of Central Europe.

Roztocze i Wyżyna Lubelsko-Lwowska (Wyżyna Wołyńska) są północno-zachodnimi fragmentami Wyżyny Wołyńsko-Podolskiej. Zbudowane są z utworów kredowych, neogeńskich i czwartorzędowych. Zarejestrowano tu 39 geostanowisk, z czego 14 ma status geoochrony. Ponad 60% geostanowisk należy do kategorii geomorfologicznej. W niniejszym artykule 4 stanowiska dziedzictwa geologicznego, Roztocza i Wyżyny Lubelsko-Lwowskiej, proponuje się umieścił na wstępnej liście geostanowisk Europy Środkowej.
