Geologija , 2006,
Abstract: Samples of Mytilus galloprovincialis were collected from entire Eastern Adriatic coast to determine δ18O and δ13C performed on calcite and aragonite shell layers. The aim of this work was to check whether shells of M. galloprovincialis are good environmental indicators (water temperature, salinity). Based on measured isotopic composition of oxygen in shell layers and assumed isotopic composition in water temperatures of calcite and aragonite of shell layers were calculated. The calculated temperatures for M. galloprovincialis shell growth of calcite and aragonite shell layer are in good agreement with measured temperatures of sea water. According to our results of δ18O and δ13C in shell layers we canseparate the locations of the investigated area into three groups: those with more influence of fresh water, those with less influence of fresh water and those of marine environments.
Reasons for Elevated Radon Levels Inside the Building in Diva a
Petra ?vab,Janja Vaupoti?,Tadej Dolenec
Geologija , 2006,
Abstract: A radon (222Rn) survey at a workplace in a public building in the town of Diva a, Slovenia, showed radon concentrations as high as 20,000 Bq m–3, with average values of 9020 Bq m–3 in winter and 2890 Bq m–3 in summer. The main radon source is an under-floor channel connecting rooms on the ground floor.Elevated radon levels at the site are possibly related to a fracture zone connected to a nearby fault.
Rapakivi texture in porphyritic dikes within the Karavanke Granitic Massif (Slovenia)
Meta Dobnikar,Tadej Dolenec,Giuliano Bellieni
Bulletin of the Geological Society of Finland , 2002,
Abstract: The northern Karavanke Granitic Massif straddles the Slovenian–Austrian border. The investigated area lies in northern Slovenia, and extends from the western Slovenian–Austrian border to the east for about 30 km, with a maximum width of 2 km. The massif exhibits a bimodal magmatic association comprising mainly syenogranite and syenite with contemporaneous gabbroic rocks. Rocks of intermediate composition are less abundant and show field, textural and chemical features suggesting that they have formed as a result of the interaction (mixing and mingling) between felsic and mafic magmas. Plagioclasemantled alkali feldspars occur in dikes of porphyritic syenite, which cut larger bodies of gabbroic rocks. Field, mineralogical, petrographic and geochemical evidences suggest that the porphyritic syenite is a hybrid rock, formed by the interaction of mafic and felsic magmas. The formation of plagioclase-mantled alkali feldspar can be explained by the introduction of alkali feldspar from felsic, syenogranitic magma into more mafic magma, causing local undercooling in the portion of mafic magma surrounding the crystals. This resulted in the growth of cellular plagioclase, with quartz infilling, in a thermally and compositionally equilibrating system.
