Recent marine sediments from Makirina bay are according to their organoleptic properties, treated as peloid or healing mud, already frequently used by local people and tourists as pomades. The application of peloids in balneotherapy is mainly intended for therapeutic treatment generally related to muscle-bone skin pathologies and purposes of wellness and relaxation. Recent studies point out that one of the main factors determining the final characteristics of peloids are grain size distribution, mineralogy, cation exchange capacity (CEC), elemental and microbiological composition of initial geological material. As reported by previous studies Makirina Bay peloid is represented mostly by sandy silt with relatively high CEC value (63.82 meq/100g). Peloid mineral composition is dominated by dolomite and quartz, followed by illite/muscovite, aragonite, halite, calcite, and pyrite. The average concentrations of potentially toxic elements (PTE) in Makirina bay peloid determined in this research are: As (17.6 mg/kg), Cr (92.09 mg/kg), Cu (44.5 mg/ kg), Mo (31.8 mg/kg), Pb (28.9 mg/kg) and Zn (69.2 mg/kg) and are comparable to previous results. PTE contents in benthic algae Codium bursa (C. bursa) are: As (8.8 mg/kg), Cr (15.7 mg/kg), Cu (5.6 mg/kg), Mo (0.7 mg/kg), Pb (3.6 mg/ kg) and Zn (16.3 mg/kg). Calculated Transfer factors (TF) from surficial peloid (0-5 cm) to benthic algae C. bursa are <1 for all analysed PTE, indicating no PTE transfer or bioaccumulation of PTE in C. bursa. Results of microbiological research correspond to previous studies and showed no coliforms and E. coli presence in Makirina bay peloid. Our studies have shown the adequate comparability of Makirina Bay peloid with peloids already successfully used in various spa centres around the world in purposes related to wellness and therapy, but additional researches (determination of Cr and Mo mobilities) are necessary before potential use of Makirina bay peloid.

Poljšica and surroundings are known for numerous interesting fossil remains. Among the rarest fossil remains are vertebrates, and in the Poljšica Oligocene these consist exclusively of fish remains. In this contribution are considered six teeth of sharks, five belonging to species Carcharias cuspidatus (Agassiz, 1843), except a single problematic tooth that can be attributed most probably to genus Cosmopolitodus.

This contribution presents remains of very rare bivalves from Miocene beds of Meljski hrib, Vukovski dol and surroundings of Lenart in Slovenske gorice. Determined were bivalves Solemya doderleini (Mayer, 1861), Lentipecten denudatus (Reuss, 1867), Limaria labani (Meznerics, 1936), Cubitostrea digitalina (Dubois, 1831) and Ostrea lamellosa Brocchi, 1814. In northeastern borders of Maribor were found in sandy and micaceous marlstones of Meljski hrib next to bivalves also remains of ophiuroids. The studied inventory of mollusks and echinoderms belongs to Miocene beds of the southern part of the Styrian basin of the Central Paratethys.

The expert decision support system for groundwater management in the shallow alluvial aquifers links numerical groundwater flow models with the water permits and concessions databases in order to help groundwater managers to quantify sustainable yield for a given groundwater body and provide additional information for sustainable groundwater management. Stand alone numerical groundwater models are used in the process of the assessment of groundwater quantitative status as well as for assessing local yield quantity during the period of maximum water demand and minimum groundwater recharge.

Geotourism is a special form of tourism which focuses on visiting geological and geomorphological sites. In the article we discuss the basic terms regarding geotourism, geodiversity and geoconservation, and then present the main features of rock shelters, i.e. landforms whose formation has not yet been elucidated. In our opinion rock shelters in Slovenian Istria have a potential to become sites for geotourism. We evaluated the geotourism potential of five rock shelter locations: Veli Badin, Štrkljevica, Mišja peč, Stena and Kavčič. The results of the evaluation show that three of the chosen rock shelter locations have a potential to develop as geotourist sites. Research confirmed our assumptions that the lack of scientific knowledge about rock shelters is a weakness from the geotourist point of view. Beside more detailed research on rock shelters, other activities, e.g. management of the sites, creating tourist activities, information material etc. are also needed if we want rock shelters to become geotourist sites in the future.
