Abstract
The enrichment of some metals (Al, Mg, Na, K, Cu, Zn, Cd) in volcanic gases is measured by an emanation coefficient, ex, relating the amount of the element x in lavas and in aerosol. Concerning the most volatile species, it appears that practically all the volcanic aerosol are produced by evaporation followed by gas-to-particle conversion and the spattered fraction appears to be negligibleFile in questo prodotto:
