Areas around seaports are prone to environmental damage. In the port of Koper, Slovenia, hematite was being transhipped during a strong wind in March 2011. The broader area was accidentally covered with hematite dust. Some members of the public and media claimed the dust was toxic and was harmful to the population. Since the soils had already been geochemically mapped, we repeated the sampling to compare the geochemical composition of the topsoil. No soil contamination was established. The enrichment factors show depletion of majority of elements. According to the distances from the dust source, SiO2, Na2O and Cr have decreasing, and Fe2O3 increasing trends. The SiO2 and Cr content correspond to the concentration of sand, and the dissolution of carbonate closer to the sea. Co and Ni are probably bound to the clay minerals. Cu, Pb, and Zn could have some anthropogenic contribution.

COBISS.SI-ID: 38586669The volume is the first Slovenian statistics textbook for geologists, so the approach is adapted to the characteristics of geological data. The author combines theoretical explanation with examples and practical solutions of problems of her own research practices. Of particular importance is the introduction of the reader in a probabilistic scientific thinking, which as opposed to descriptive, deterministic approach, attributes the appropriate probability to each outcome of the investigation.

COBISS.SI-ID: 268529408The representative successions of the Bled, Tolmin and Bovec basins, and the Julian High are described and illustrated. The stratigraphy of these locally recognized basins is correlated regionally and discussed in the larger framework of the evolution of the Adriatic continental margin. The paper is written as a field-trip guide for a post-conference excursion of the 29th IAS Meeting.

COBISS.SI-ID: 2076245Castanar Cave is a touristic cave in Extremadura, Spain, which has been object of numerous geological, environmental and biological studies in the last 15 years. All this information is presented in this fully illustrated book, addressed to the general public. The chapter “La cueva está viva y es un laboratorio natural” focuses in the description of the speleothems. It explains the basics of karst proceses and speleothem deposition, describing each morphological type. The mineralogy and diagenetic processes that affect the cave deposits are also explained.
F.27 Contribution to preserving/protecting natural and cultural heritage
COBISS.SI-ID: 39964461Laboratory experiments were done to test insecticidal activity of diatomaceous sediments from several localities in Slovenia, Greece and Serbia. The tests were carried out at different temperatures, humidity and concentrations of the agent. We observed that the most significant factor increasing insecticidal activity is silica content. The samples from Slovenian localities were more effective at higher relative humidity (75%) while the efficiency of other samples increased with lowered humidity. This fact is related to higher content of clay minerals in Slovenian samples. The results are an important contribution to the development of environmentally friendly insecticides.
