The first systematic geochemical survey of urban soil in the old industrial town of Maribor, Slovenia, was performed in 2016. Soil properties (pH, electrical conductivity, total carbon, organic ...matter) and 56 aqua-regia soluble elements were determined from 118 sampling sites. A relatively clear distinction between naturally and anthropogenically distributed elements was found by inspection of the spatial distribution of their highest levels and by applying Spearman rank correlation coefficients. The median levels of Cu, Pb and Zn in the soil are significantly higher than the corresponding Slovenian median levels. Their enrichment is typically found in industrialised zones and the old town centre, suggesting that the elevated levels are historical. In addition, current industrial activities, as well as road and rail traffic contribute to increased levels. Additionally, a few isolated locations with significant enrichment of several elements were identified. Widespread diffuse contamination was not identified. Spatial distribution patterns of many elements (e.g., Co, Cr, Fe, V) are influenced by the geological setting of the area, as their highest soil levels are concentrated at the foot of the igneous-metamorphic Pohorje Mountains.
•First systematic topsoil geochemical survey of urban area of Maribor•Levels of 56 elements and soil properties (pH, EC, TC, TOC, SOM) are presented.•Cu, Pb and Zn show the highest spatial variability.•Cu, Pb and Zn enrichments are typical for industrial zones and old town centre.
U članku se analiziraju stambena naselja RE u Sloveniji s obzirom na njihovu kvalitetu i integritet koje su se mijenjale ovisno o socio-ekonomskim okolnostima: najprije u kontekstu socijalističkog ...društvenog poretka u vrijeme Jugoslavije (1945.-1990.), a zatim nakon stjecanja državne neovisnosti u okolnostima slobodnog tržišta. Rad donosi istraživanje stambenih naselja u Mariboru u različitim vremenskim razdobljima. Rezultati ukazuju na kvalitativne razlike u razdoblju skandinavskog utjecaja, kao i parametre inženjerske ekonomije nakon stambene reforme i tržišne ekonomije nakon stjecanja nezavisnosti.
The paper identifies the quality and integrity of residential environment RE in Slovenia that changed according to socio-economic circumstances when the new socialist society in the Yugoslav era (1945-1990) was formed and was substantially changed in the post-independence era of the liberal market society. The research of RE from different periods was conducted in the city of Maribor. The results indicate differences in quality in the period of the Scandinavian influence, engineering economy parameters after the housing reform, and of the market economy after independency.
Kyanite-rich and quartz-rich eclogites occur as lenses within amphibolite-facies quartzo-feldspathic gneisses in the Pohorje Mountains, Northern Slovenia, that form the easternmost Austroalpine ...basement. Major and trace elements indicate that the kyanite-rich eclogites were derived from plagioclase-rich gabbroic cumulates, whereas the quartz-rich eclogites represent more fractionated basaltic compositions. Both varieties are characterized by a LREE-depleted N-MORB type REE signature. Geothermobarometry and
P–
T pseudosections indicate that eclogites equilibrated at 1.8–2.5 GPa and 630–700 °C, consistently with the lack of coesite and with equilibration conditions of the chemically similar eclogites from the adjacent basement units at Koralpe and Saualpe type localities. Decompression reaction textures include (i) clinopyroxene–plagioclase intergrowths after omphacite, (ii) replacement of kyanite by corundum–plagioclase–spinel±sapphirine symplectites, (iii) breakdown of phengite to biotite–plagioclase sapphirine symplectites. The results of this study indicate that Koralpe, Saualpe and Pohorje high-pressure rocks represent former MORB-type oceanic crust that was subducted in the course of the late Cretaceous (approximately 100 Ma ago) collision between the European and the Apulian plates.
