Late Pleistocene vertebrate - bearing deposits at San Teodoro Cave (North-Eastern Sicily): Preliminary data on faunal diversification and chronology
2008
Abstract This paper deals with the chronology and the possible correlations among levels of different excavated areas in the Pleistocene vertebrate-bearing deposits at the large San Teodoro Cave (North-Eastern Sicily). Two trenches have been excavated along the eastern side of the cave, located at a distance from the entrance, respectively, of 8 m ( α trench) and 28 m ( β trench) and at different depths. Lithological features, biometrical data from small mammals and ecological data from molluscs point to similar environmental conditions for the α trench deposits and those located along the eastern wall of the cave in the eastern part of the β trench. The same evidence, and the taphonomic fe…
Carbon stocks in a 50‑year‑oldEucalyptus camaldulensisstand in Sicily, Italy
2015
Eucalyptus stands in semi-arid areas may contribute to enhance carbon (C) stocks in both biomass and soil. However, the limited information available is mainly focused on short-rotation plantations. In this study, the above- and below-ground C pools in five 50-year-old Eucalyptus camaldulensis Dehnh. stands planted on Miocenic evaporitic deposits in Sicily, Italy, with a xeric and thermic pedoclimate, were measured. Above-ground biomass was determined by partitioning and weighing branches, stem and leaves. Below-ground C pools included the determination of litter, root biomass, and soil organic and inorganic C. In terms of the above-ground biomass, the E. camaldulensis stand accumulated on …
Devona Daugavas svītas dolomītu litoloģiski rūpnieciskie tipi atradnēs Rīgas apkārtnē
2020
Bakalaura darbā “Devona Daugavas svītas litoloģiski rūpnieciskie tipi atradnēs Rīgas apkārtnē” ir raksturota Daugavas svītas dolomītu uzbūve ģeoloģiskajā griezumā, dolomītu veidu izplatības likumsakarības 5 dolomīta atradnēs Rīgas apkārtnē un Doles salas dolomīta atsegumā, kā arī nodalīti dolomītu litoloģiski rūpnieciskie tipi. Pētījuma ietvaros veikti lauka darbi, kuros veikta atseguma sienu dokumentācija. Pētījuma rezultātā secināts, ka 1. tipa ļoti izturīgie un 2. tipa izturīgie dolomīti ir visplašāk pārstāvēti Tūrkalnes, Kranciema un Kalnciema atradnēs.
