Pegmatites are texturally complex igneous rocks marked by some combination of coarse but
variable crystal size, mineralogical zonation, prominent anisotropy of crystal orientations …

Knowledge of temperature and pressure, however qualitative, has been central to our views
of geology since at least the early 19th century. In 1822, for example, Charles Daubeny …

A revised regular solution-type thermodynamic model for twelve-component silicate liquids
in the system SiO 2-TiO 2-Al 2 O 3-Fe 2 O 3-Cr 2 O 3-FeO-MgO-CaO-Na 2 OK 2 OP 2 O 5-H …

For petrological calculations, including geothermobarometry and the calculation of phase
diagrams (for example, P–T petrogenetic grids and pseudosections), it is necessary to be …

Abstract Cameron et al.(1949) devised the nomenclature and delineated the patterns of
internal zonation within granitic pegmatites that are in use today. Zonation in pegmatites is …

We introduce a novel scheme that enables natural silicic glasses to be projected into the
synthetic system Qz–Ab–Or–H 2 O in order to relate variations in volcanic glass chemistry to …

Most granitic batholiths contain plutons which are composed of low-variance mineral
assemblages amenable to quantification of the P–conditions that characterise emplacement …

Although many formulations of plagioclase+ liquid equilibria have been calibrated in the last
decade, few models specifically address the issue of temperature (T) prediction. Moreover …

More than 5000 km 3 of nearly compositionally homogeneous crystal-rich dacite (∼ 68 wt%
SiO 2:∼ 45% Pl+ Kfs+ Qtz+ Hbl+ Bt+ Spn+ Mag+ Ilm+ Ap+ Zrn+ Po) erupted from the Fish …

Abstract The 1.43 Ga Sherman batholith, southeastern Wyoming, USA, shows extreme A-
type petrochemical characteristics compared with other Mid-Proterozoic granite batholiths of …
