Journal ArticleDOI
Dissolution of basaltic glass in seawater: Mechanism and rate
TL;DR: In this paper, a series of experiments designed to study the structure and chemical composition of alteration layers formed on the surface of artificial tholeiitic glass altered in artificial seawater were performed at 60°C, 1 bar and 350 bars in non-renewed conditions.
Journal ArticleDOI
Kinetic aspects of basaltic glass dissolution at 90°C: role of aqueous silicon and aluminium
TL;DR: 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.
Journal ArticleDOI
Nature and role of natural alteration gels formed on the surface of ancient volcanic glasses (Natural analogs of waste containment glasses)
TL;DR: In this article, an overview of the geochemical alteration of basaltic glass, considered for over 20 years as a suitable natural analogue for nuclear borosilicate glasses, is provided.
Journal ArticleDOI
Dissolution of subglacial volcanic glasses from Iceland: laboratory study and modelling
TL;DR: In this article, the chemical composition of palagonite (alteration crust formed on the surface of the glass) is almost identical with that of the clayey material filling the intergranular spaces of the rock.
Journal ArticleDOI
Geochemical evolution of basaltic rocks subjected to weathering: Fate of the major elements, rare earth elements, and thorium
TL;DR: In this article, the dissolution reaction progress (mass of dissolved glass per liter of solution) governs the chemistry of the secondary phases, which control the residence time of the solution through their influence on rock permeability.
