Fig. 7: Nanolite-bearing viscosity of AND100 samples.
From: Nanoscale chemical heterogeneities control the viscosity of andesitic magmas
Normalized viscosity as a function of temperature and FeOtot + TiO2 content (wt%) of their STEM-EDS-derived residual matrix composition (Fig. 5; Table 2). Viscosity is normalized to the AND100 melt (Table 1; Fig. 2). The MP sub-index represents the temperature (°C) of micropenetration measurement. The black curves correspond to the viscosity as a function of FeOtot + TiO2 content (wt%) at 660, 723 and 808 °C respectively. A viscosity calculator is provided as Supplementary Data.
