“…Aeolian dust accretion in terra rossa soils can also originate from a wide range of alluvial deposits, such as sand dunes, desiccated alluvial planes and Quaternary loess (Amit et al, 2020;Erel & Torrent, 2010;Lehmkuhl et al, 2020), especially during cold and arid periods of sea level lowstands and subsequent continental shelves' exposure (e.g., Razum et al, 2023). In the Mediterranean alpine hinterland, thin drapes of Sahara dust-rich soils are found on glacial plateaus, moraines and outwash plains (e.g., Rellini et al, 2009), but also on non-glacial karst plateaus (e.g., D'Amico et al, 2023). Most of the Mediterranean mountains are built up by carbonate rocks; hence, the aeolian input to alpine soil formation occurs in parallel with colluvial deposition of carbonate erosion and dissolution products that form a characteristic insoluble residue incorporated in the soil sequences (Durn, 2003;Kirsten & Heinrich, 2022;Varga et al, 2016).…”
