Phase equilibrium experiments were performed in the MgO–SiO2–H2O system, along with fluorine (MSH + F), at conditions between 800–1000 °C and 2.0–2.5 GPa to constrain the solubility of fluorine in humite-group minerals and to determine fluor

Engine durability tests are used by manufacturers to demonstrate engine life and minimum performance when subjected to doses of test dusts, often Arizona Road Dust. Grain size distributions are chosen to replicate what enters the engine; less attenti

Pyroxenes of general stoichiometry Mg(Ge x Si1−x )O3 were encountered in attempts to synthesise Ge-substituted talcs at 0.2 GPa, 650–700 °C. Orthopyroxenes (Pbca) of compositions x = 0.21, 0.30, and 0.34 were identified, and also a P21/c clinopy

An amphibole close to eckermannite in composition, ideally Na3Mg4AlSi8O22(OH)2, was encountered in experiments on a bulk composition close to that of glaucophane at 6.2 GPa, ∼550–650 °C. The synthetic amphibole has an average composition corresp
