Kinetic aspects of basaltic glass dissolution at 90°C: role of aqueous silicon and aluminium
TLDR
In this article, the steady-state dissolution rates of a synthetic basaltic glass were measured in an open-system mixed flow reactor as a function of solution composition at a temperature of 90°C and over the pH range 7.8 to 8.3.About:

General kinetic description of multioxide silicate mineral and glass dissolution
TL;DR: In this paper, a general kinetic description of major rock forming multioxide silicate dissolution is developed by assuming the relative rates at which various metal-oxygen bonds are broken within a multioxide structure are consistent with the relative dissolution rates of the single (hydr)oxides.

Reaction mechanisms in the geopolymeric conversion of inorganic waste to useful products
TL;DR: A conceptual model for geopolymerisation is presented, allowing elucidation of the individual mechanistic steps involved in this complex and rapid process, based on the reactions known to occur in the weathering of aluminosilicate minerals under alkaline conditions.

Mechanism, rates, and consequences of basaltic glass dissolution: II. An experimental study of the dissolution rates of basaltic glass as a function of pH and temperature
TL;DR: In this paper, surface reaction controlled basaltic glass dissolution rates at far-from-equilibrium conditions were quantified, and the dissolution rates were interpreted within the context of a multioxide dissolution model.
