Fibrous microcrystalline calcite (FMC) is one of the most common and widespread forms of secondary calcium carbonate in vadose terrestrial environments (caves, soils, surficial sediments, etc.). Many studies have shown positive association of microbial communities with fibrous calcite, however, the controversy remains regarding the role of microorganisms in carbonate mineralization. We have shown uncertainties about microbial biomineralization and presented a hypothesis on a possible passive role of organic matter in FMC precipitation.

COBISS.SI-ID: 37219117During transhipment of cargo at a very strong wind in 2011 in the Luka Koper port came to dusting with iron oxide. As in 2008 we have already sampled the soil in the vicinity of Koper, re-sampling enabled to assess the impact of dust on soil contamination. Comparison of the results from both years did not reveal any statistically significant elevated levels of elements due to hematite dusting. Enrichment factors of Al2O3, F2O3, MgO, Co and Ni do not support soil pollution as a consequence of dusting. The differences in the contents of SiO2, Na2O, MnO, LOI, CTOT and Cr according to the distance from the port are geological: increased volume fractions of sand and more dissolved carbonate in sediments closer to the sea.

COBISS.SI-ID: 1146718The genetic relationship between clays and precipitation of carbonates has lately received an increased interest (e.g., in the exploration of giant oilfields in the southern Atlantic), since a clear correlation between Mg-Si films/needles/gels and carbonate minerals, particularly dolomite, has been recognized. The genetic and diagenetic relationships between Mg-clays and Mg-carbonates of Castañar Cave show that the the presence of colloidal Si-Mg phases in the system, biotic or abiotic in origin, may play an important role in the precipitation of dolomite.

COBISS.SI-ID: 37522477The report is a contribution to the European project DRINKADRIA WP4 dealing with the regional characteristics of climate and climate change in a wider range of Slovenian pilot areas. First we analysed observed air temperature and precipitation from two meteorological stations (Bilje and Portorož) located in western Slovenia. Climate characteristics and variability are presented for 1961 – 1990 reference time period and trends are calculated for the whole span of available data, i.e. 1956 – 2011 for temperature and 1961 – 2011 for precipitation. The second part of the report comprises simulation of present and future climate based on three different regional climate models; Aladin (Bubnova et al., 1995), Promes (Castro et al., 1993) and RegCM3 (Pal et al., 2007)
D.06 Final report on a foreign/international project
COBISS.SI-ID: 1183070With its paleontological inventory, the Lipovica active quarry is one of the richest sites of Middle Miocene fossils in Slovenia. Bivalves and sea urchins are the most abundant. Red algae, gastropods, decapods, bryozoans, brachiopods and vertebrates (mostly shark teeth) also occur. The thorough description of these fossils (120 pages) is an important contribution to the knowledge and conservation of the Slovenian natural heritage.
