TL;DR: In this paper, a model that predicts the non-Arrhenian Newtonian viscosity of silicate melts as a function of T and melt composition, including the rheologically important volatile constituents H2O and F, is presented.

TL;DR: In this paper, a non-Arrhenian model for multicomponent silicate melt viscosity has been proposed, which accommodates the effects of composition via an empirical parameter, termed the structure modifier content (SM).

TL;DR: In this article, the authors investigated the viscosity of hydrous Etna lava in order to better understand eruptive processes which characterize this volcano, and they found that at temperatures ranging from 1,050 to 1,150°C and with water contents between 0.5 and 2.3% (eruptive conditions), their results were in reasonable agreement with those calculated using Shaw's model, and much lower than those experimentally determined in a previous study.

TL;DR: In this article, the authors investigate the high temperature (1131°C) of a basaltic volcano and investigate its behavior in terms of the textural evolution and rheological properties of eruptive products.

TL;DR: In this paper, a lower limit for the time-temperature envelope that gives rise to densely welded deposits and constraints on their emplacement temperature has been determined for natural multicomponent melts using differential scanning calorimetry.
