Granite is one of the most important components of the continental crust on our Earth; it thus
has been an enduring studied subject in geology. According to present knowledge, granite …

Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

Improvements in experimental, analytical and computational methodologies together with
published studies yielding seemingly contradictory results prompted us to return to the …

Silicic magma systems are of great scientific interest and societal importance owing to their
role in the evolution of the crust and the hazards posed by volcanic eruptions. MELTS is a …

The application of the Ti-in-zircon thermometer to granitic rock requires consideration of a_
TiO _ 2 a TiO 2 and a_ SiO _ 2 a SiO 2 during zircon crystallization. Thermodynamic …

A clear understanding of the processes responsible for observed rock microstructures is
essential for making reliable petrogenetic interpretations, including inferences made from …

Synthetic quartz was grown in rutile-bearing H2O (±NaCl) fluids at 600–800° C and 1–
10kbar by dissolution and reprecipitation of quartz in a small thermal gradient. Rapid …

Titanium is one of many trace elements to substitute for silicon in the mineral quartz. Here,
we describe the temperature dependence of that substitution, in the form of a new …

Quartz and rutile were synthesized from silica-saturated aqueous fluids between 5 and 20
kbar and from 700 to 940° C in a piston-cylinder apparatus to explore the potential pressure …

A model for the thermodynamic properties of rhombohedral oxide solid solutions in the
system Fe~ 2~ O~ 3~-FeTiO~ 3~-MgTiO~ 3~-MnTiO~ 3~(containing minor amounts of Al~ 2 …
