Introduction
I am interested in mineralogy, geochemistry and micromorphology of palaeosols at regional unconformities and in environmental mineralogy. I am particularly involved in investigation of clay minerals as sensitive indicators of the geochemical environment of pedogenesis and diagenesis and therefore can be used for palaeonvironmental and palaeoclimatic reconstructions. Recently I am also involved in investigation of natural habitat of carbapenem-resistant bacteria in soils/sediments/technosols.

The quantification of the proportion of end-members in polygenetic soils and sediments is usually based on grain size distribution and geochronological, geochemical and mineralogical data. Most of these techniques have inherent disadvantages, such as selective weathering of the source rock, hydraulic sorting of the sediment during transportation, f...
The geochemical signature of weathering and pedogenesis in a temperate humid climate on two parent material types in the foothills of Medvednica Mt. was studied. Five soil profiles on Miocene marls and three sections of Plio-Quaternary (PlQ) proluvial sediments with overlying soil and weathered material were analyzed. The (clay) mineralogy of all p...
The Minjera bauxites are the first analysed and mined bauxites in the world. They are a group of pyritised bauxites situated in northern Istria, developed during the subaerial exposure phase which marked a major part of the Late Cretaceous and Palaeocene in northern Istria. In this study, the morphology, petrography, mineralogy, geochemistry as wel...

Glauconite formation is generally perceived as a process occurring in deep-marine environments, but in the last
few decades its formation in shallow-marine environments is progressively more recognised and utilized for
palaeoenvironmental reconstructions. One such example is the lower Kimmeridgian to upper Tithonian Zlatni Rt
palaeosol, which is es...
Loess deposits are widespread in continental Croatia, but sporadic in its Mediterranean region. During most of the Upper Pleistocene, sea level was lower and northern part of the Adriatic was a large sedimentary basin. Alluvial sediments, deposited therein mainly by the Po River, were subjected to wind deflation/transport. Part of the entrained dus...
Coherent provenance studies of soils that take into account data processing and the limitations arising from the physiochemical properties of the source material are scarce. In this study, the provenance of four terra rossa soils on the Istrian peninsula and four terra rossa soils on the island of Susak is investigated based on the heavy mineral as...

The soil was sampled immediately and 1, 2, 4, and 6 months after the fire. The fire in...
Pipeline spills and pollution of the environment by crude oil pose a threat to natural resources, especially soil and water. One such incident occurred on 25 September 2018 in the area of Budrovac (Croatia; 46°00′14.6″ N 17°04′16.8″) on agricultural land as a pipeline spill. Bioremediation of the contaminated soil was carried out with organic pollu...
DETAILED ABSTRACT
Soil water regime refers to soil water's quantity, retention, and movement. It is therefore considered one of the
key components of overall soil fertility. Among others, it directly affects the redox potential of the soil, which is often
used to assess soil aeration and the availability of plant nutrients. Instead of taking expens...

Clinically significant A. baumannii isolates have been recorded in wastewaters, natural aquatic habitats and soils contaminated by human waste. The aim of this study was to investigate the potential application of unmodified (NZ) and Ag-modified (AgNZ) na...
Bacteriological pollution, especially that including clinically important bacteria, of the aquatic environment caused by anthropogenic pressure attracts much attention with regard to public health. Reports to date have not addressed the concentration of emerging carbapenem-resistant bacteria (CRB) in riverine ecosystems, and the source of this poll...
Recently, concerns have been raised about the possibility of Acinetobacter baumannii transmission between animals and humans. So far, A. baumannii has been reported in animals with which people can come into contact. The presence of this pathogen in animal manure presents an equally important public health risk. In this study, we report the finding...
Loess-derived sediments represent the most widespread soil parent materials in the Pannonian region of Croatia. Pseudogley, as the most common soil type in this region, developed mainly on such parent materials. Pseudogleys largely correlate with the WRB Reference Soil Group of Stagnosols. On the General Soil Map of Croatia at scale 1: 50 000 (GSM...

The carbapenem-resistant bacteria (CRB) are currently at the top of the WHO priority list of bacteria that pose the greatest threat to human health. Considering that soil is one of the important environments for the emergence of antibiotic-resistant bacteria, we isolated and quantified cultivable CRB in soils across Croatia, including ones affected...
Stagnosols (Pseudogleys) are the most widespread soils in the Pannonian region of Croatia. They largely formed on non-calcareous loess materials. These loess materials probably originated from different sources and were deposited in partially different environments. Hence, the loess-derived parent materials of Croatian Stagnosols may be considered...
In a karst pit above City of Rijeka in Croatia the hazardous industrial waste was continuously disposed from 1955 to 1990, and later it was periodically used as an illegal dump site. The surface part of a technosol at the edge of dump was analysed mineralogically, geochemically and bacteriologically. From the technosol rich in petroleum hydrocarbon...

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...
Illegal dump sites of solid waste are widespread problem in Croatia. They can be the source of pathogenic
and moreover multi-drug resistant bacteria, from which these bacteria can be leached from waste by storm
water and thus spread in nature. In the acid paleosol from Istria predominantly composed of illitic material and illite/smectite mixed-laye...
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...
Three samples of terra rossa were shown to be efficient adsorbents of phosphate

Problem of stratigraphic correlation of open sediment succesion...
Even in karst areas, considerably thick soils can be found in accumulation zones. Here, the degree of groundwater vulnerability depends not only on the thickness, but also on the hydraulic conductivity and retention properties of the soil cover. The hydraulic conductivity of fine-grained karst soils from Slovakia, Croatia and Austria was studied wi...
The aim of this study was to geochemically and mineralogically assess materials from two already closed pits. Total testing and leachate testing (Equilibrium Leach Test and Sequential Leach Test) of topsoil, waste stabilized with lime and underlying rock was performed on composite samples. An analysis of underground water from underlying rock was a...
The geological framework of the Republic of Croatia gives rise to a relatively simple distribution of the mineral construction resources. The Dinaric karst region is characterized by the production of limestone and dolomite both as aggregates and dimension stone, and due to the occurrence of flysch bedrock sequences, it is a major cement producing...
With the use of the optimised three-step BCR sequential-extraction procedure it was possible to assess the mobility of selected elements in soil profiles from Croatian and Slovakian karst terrains. The soils in the Croatian karst were enriched in Cr, Ni, V, Mn, Cu, Cd and Mo, while soils from the Slovak Karst had high Pb and Zn concentrations. It w...
Phase-selective sequential extraction techniques have been used to identify the residence sites of metals in soils developed
over a historical silver-mining site. The operationally defined phases selected for extraction have been assigned to the following
five fractions: adsorbed, bound to carbonates, bound to Fe-Mn oxides, bound to organic matter...
Terra rossa in Istria is situated on the Jurassic-Cretaceous-Paleogene carbonate plain and is considered a polygenetic reddish soil which bears typical terra rossa Fe-oxide characteristics (e.g. Fed and Fed/Fet) and might have been created from Pliocene onward during favourable climatic periods (Pliocene, older Pleistocene and interglacial periods...
In the past, the term “terra rossa” became quite a common indication for all limestone derived red soils in the Mediterranean region. Today, in some classification systems based on the Mediterranean climate as the major soil differentiating criterion, the term terra rossa is used as a name for the soil subclass “Modal Fersiallitic Red soil” when si...
Two types of manganese nodules were observed in the Peru Basin: large botryoidal nodules in basins and small ellipsoidal nodules on slope positions. The sediment in areas with large botryoidal nodules contains a thinner and weaker oxidation zone than the sediment under small ellipsoidal nodules, indicating that diagenetic processes in the sediment,...
Haematite and goethite are the predominant pedogenic mineral phases in terra rossa from Istria. Limited variation of selected Fe oxide characteristics in analysed samples indicates the specific pedogenic environment in which terra rossa is formed. The mean value of the Fed/Fet ratio, taken as an index of weathering is 0.7 and reflects quite a high...
Mineral and ore occurences at Mt. Ivanščica are situated in the Middle Triassic carbonate rocks and are of epigenetic origin. These occurences are characterised by simple paragenesis of primary sulphides of leads and zinc and traces of sulphides of iron and copper. This mineralization is similar to Mississippi Valley Pb-Zn deposits.
The purpose of this study was a geochemical assessment of soils developed on a historical Pb–Ag mining site (galena with approx. 500 mg/kg of Ag) situated near the chapel of Sv. Jakob on the crest of Mt. Medvednica near Zagreb. A total of 100 brown forest (0–25 cm) soil samples were collected from the regular grid covering an area of approximately...
Terra rossa in Istria is situated on the Jurassic–Cretaceous–Paleogene carbonate plain and is considered a polygenetic reddish soil which bears typical terra rossa Fe-oxide characteristics (e.g., Fed and Fed/Fet).

Red paleosol (RP) covering the carbonate basement exposed at the bottom of the loess section was investigated to give a systematic and deeper palaeopedological insight into reddish materials on the island of Susak (Croatia). RP contains different types of Fe and Fe/Mn nodules. After detailed micromorphological analysis with polarizing microscope, nodules were analyzed by the means of scanning electron microscopy (FESEM) with EDXS probe and X–ray diffraction. Some nodules contain features as shown on photographs 1 and 2.
My student found this feature in the Cretaceous clayey paleosol. The outer shell is rich in carbon and the inner part is composed of pure clay. As a clay scientist I have no experience with this kind of features and can only guess that it is of biological origin. If someone has experience any suggestion is highly appreciated.
