Nucleation delay in water-saturated rhyolite during decompression in shallow volcanic systems and its implications for ascent dynamics

We developed a model of feldspar nucleation delay during decompression in water-saturated rhyolite based on classical theory (CNT). With the thermodynamic and kinetic parameters proposed this study, agrees with experimental results study to within factor two. To account for variety conditions encountered by magma ascent, we propose expanding model, isothermal decompression, wider range pressures temperatures (i.e. non-isothermal conditions). present new measurements growth rates rhyolite, emphasizing importance accurately calculating order estimate rates. Using these data, method estimating ascent rate microlites. The findings hold promise better understanding volcanic timescales conduit, as well possibility extending our more complicated scenarios changing pressure temperature.
