MagmaVisc

Calculate silicate melt viscosity from major oxide composition and temperature

Scientific AIFree

MagmaVisc computes viscosity of silicate melts using the GRD model calibrated against 14,600 experimental measurements spanning basaltic to rhyolitic compositions. The tool accounts for dissolved water and fluorine content effects on non-Arrhenian viscosity-temperature relationships. Output includes fragility index and glass transition temperature estimates for volcanic eruption style classification.
