The contribution of tephra constituents during biogenic silica determination: implications for soil and palaeoecological studies
Biogenic silica (BSi) is used as a proxy by soil scientists to identify biological effects on the Si cycle and by palaeoecologists to study environmental changes.Alkaline extractions are typically used to measure BSi in both terrestrial and aquatic environments.The dissolution properties of volcanic glass in tephra deposits and their nanocrystallin
