20.500.12556/DiRROS-15464 Characterization of atmospheric deposition as the only mineral matter input to ombrotrophic bog Ombrotrophic peatlands contain a very small percentage of mineral matter that they receive exclusively from atmospheric deposition. Mineral matter deposited on the Šijec bog was characterized using scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS). We collected solid atmospheric deposition from snow, rainwater, and using passive samplers. Samples were collected at average atmospheric conditions and after two dust events. Size, morphology, and chemical composition of individual particles were determined. We distinguished four main particle groups: silicates, carbonates, organic particles, and Fe-oxyhydroxides. Silicate particles are further divided into quartz and aluminosilicates. Proportions of these groups vary between samples and between sample types. In all samples, silicate particles predominate. Samples affected by dust events are richer in solid particles. This is well observed in passive deposition samples. Carbonates and organic particles represent smaller fractions and are probably of local origin. Iron-oxyhydroxides make up a smaller, but significant part of particles and are, according to their shape and chemical composition, of both geogenic and anthropogenic origin. Estimated quantity and percentage of main groups vary throughout the year and are highly dependent on weather conditions. Dust events represent periods of increased deposition and contribute significantly to mineral matter input to peatlands. atmospheric deposition SEM/EDS mineral matter peatland true false true MDPI Angleški jezik Ni določen Neznano 2022-09-08 13:53:54 2022-09-08 13:53:54 2022-11-16 14:36:12 0000-00-00 00:00:00 2022 0 0 22 str. no. 8 vol. 12 2022 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2022-08-02 55 2075-163X 10.3390/min12080982 120692227 minerals-12-00982-v2.pdf minerals-12-00982-v2.pdf 1 E289950E2D9FAB24B90C1A5A256635B3 7b02f3d6bc560eb9abb9f74204246d998b5542cc7d374ba8c021c684f9c02089 8da343c4-2f5d-11ed-bea5-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20467 minerals-12-00982-s001.zip minerals-12-00982-s001.zip 1 B4E66E93330F35DEC9FCF5CDA1033A40 5dbe3a1ba9ef88d1310614105feb3d2d96c21418eb947208a42271b8a16d79fc 7c31dddc-2f5d-11ed-bea5-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20466 Geološki zavod Slovenije 0 0 0
