This study compares the differences between the distribution of trace elements and rare-earth elements (REEs) formed under reducing and oxidizing soil conditions during pedogenesis on carbonate bedrock. Terra rossa (TR) soils, representing pedogenesis under oxic conditions, and Cretaceous palaeosols (CP), representing pedogenesis under reducing con...

Environmental geology is scientific discipline dealing with the interactions between humans and the geologic environment. Many natural hazards, which have great impact on humans and their environment, are caused by geological settings. On the other hand, human activities have great impact on the physical environment, especially in the last decades...

A soil geochemical survey of the city of Sisak, Croatia, and its surroundings was done to determine the concentration, spatial distribution and sources of the elements in the soil. Factor analysis indicates 8 factors describe the geochemical variations in the topsoil: 4 anthropogenic, 2 geogenic and 2mixed ones. The main influence in the urban and...

Weathering processes cause significant changes in the engineering properties of rocks. Slope instability in flysch rock formations along the northern Adriatic coast of Croatia is related to the effects of weathering on the shear strength of siltstones from the flysch rock mass. Therefore, changes in geotechnical properties according to weathering g...

Iron (oxy)hydroxides play an important role in a variety of disciplines, among others, environmental and exploration geochemistry, mineralogy, geology and soil science. In selective leaching procedures, either for the removal of (oxy)hydroxide prior to clay minerals analysis or for the determination of metals in reducible soil/sediment fractions, i...

The objective of this work was to build a prognostic water flow model and potentially toxic elements (lead, cadmium, zinc) transport model in the unsaturated zone. Research was conducted in the catchment area of Kosnica regional wellfield, where the unsaturated zone is characterised by Fluvisol. Lower sorption capacities were determined in the firs...

Potentially toxic elements (PTEs) pose a threat to human health as they can easily enter the human body via ingestion of polluted soil/sediment. In order to estimate the bioavailability and assess the health impact on people, measurement of the oral bioaccessibility of a pollutant is crucial. Various laboratory based in vitro tests which mimic huma...

This study presents new insights on the provenance, genesis, and post-depositional history of theMiocene pyroclastic tuffaceous layers (~18 and ~15 Ma) preserved in argillaceous sediments and interbedded within the lacustrine sedimentary succession of the Sinj Basin in central Dalmatia (Dinaride Lake System, Croatia). Analysed tuffs are classified...

The first written document of viniculture and wine production in Istria dates from antiquity, indicating a very long tradition. Istrian wines are very well known for its quality. It has been commonly accepted that quality, taste and style of wine depends on terroir, i.e. the local environment (eg. soil, bedrock, climate). Good terroirs are those pe...

A Bronze Age ceramics and possible raw materials in the area of Turopolje in northwest Croatia have been studied. The main goal of this study is to determine the availability and types of raw materials, as well as to reconstruct the technological processes (preparation of raw material and firing technique) of pottery making at archaeological site K...

A strong debate arises nowadays concerning the concept of terroir, mainly referring to the relationship between soil properties and wine quality. In our ongoing study we investigate soils in three vineyards where Istrian Malvasia, the most widespread cultivar in Istria is grown. Our goal is to compare their mineral composition, physical and chemica...

250 million years ago the area around Hallstatt was covered by a large ocean. Even at that time climate change was a fact: Due to global warming water evaporated and huge amounts of salt crystallized. 7000 years ago people discovered these salt deposits, settled in Hallstatt and started salt mining. Pottery was used in everyday life and also as gra...

This paper presents a conceptual model of the Zagreb aquifer system. The conceptual model can be applied to groundwater status risk assessment and pollution risk assessment at the local scale, thus satisfying both environmental and preventative/limitation objectives of the Water Framework Directive (WFD) and Groundwater Directive (GWD). Its main pu...

Conceptual model of flow and solute transport in unsaturated zone at Kosnica site, which is the basis for modeling pollution migration through the unsaturated zone to groundwater, is set up. The main cha-racteristics of the unsaturated zone of the Kosnica site are described. Detailed description of investigated profile of unsaturated zone, with all...

The subject of this study is Fluvisol developed on the floodplain of Sava River. Goal of the study is one-dimensional transport model on column scale. The purpose of the study is better understanding of sorption and migration of selected trace elements through the soil column. Two undisturbed soil samples for each of two best developed horizons of...

Groundwater dependent ecosystems (GDEs) include valuable ecosystems such as springs, wetlands, rivers, lakes and lagoons. The protection of these systems and services they provide is highlighted by international agreements, i.e. Ramsar convention on wetlands, and regional legislation, i.e. the European Water Framework Directive. Groundwater provide...

Canonical correlation analysis (CCA) is used in this study in order to trace the lineage of overbank sediment from the initial erosion of the parent rocks down to deposition of detrital material in alluvium of the small mountainous watersheds of the Žumberak area, Croatia. It helps to elucidate relations between the hierarchically structured system...

Flysch deposits that crop out in the elongated coastal area of the Vinodol Valley (External Dinarides), and particu-larly in the Slani Potok ('Salty Creek') catchment, are characterized by excessive erosion. Formation of badlands, creeping and sliding processes have been related to crystallization of thenardite. Unusually intense erosion is caused...

The Pleistocene loess and Holocene alluvial sediments are dominant lithological members of Eastern Slavonia. The Upper Pleistocene loess/palaeosol section “Šarengrad”, representing the oldest loess deposits in the region, was investigated using field and laboratory research methods.. Investigated section is located on the south bank of the Danube R...

The soil is generally defined as a surface layer of the earth’s crust made of mineral particles, organic matter, water, air and living organisms. Soil connects the earth, air and water and hosts a larger part of biosphere. Due to extremely slow process of creation, it is considered as non-renewable, or in the best case, conditionally renewable reso...
