  author={Gnoncn R. RossvreN and S. Gnnw},
Polarized infrared spectra of a suite of sillimanite samples from high-grade regionally metamorphosed rocks and associated quartz veins and pegmatites (upper-amphibolite to pyroxene granulite facies), from xenoliths in basaltic rocks, and from alluvial deposits indicate that hydroxyl is the dominant hydrous species bound in sillimanite. Absorption bands at 3556, 3329, 3300, and 3248 cm-L are characteristic of many of the samples. Heating experiments indicate that only above 700'C is weight loss…

Co-ordination of boron in sillimanite
Ion-Microprobe analyses of six sillimanites associated with kornerupine show that the sillimanite can incorporate from 0.035 to 0.43 wt. % B_2O_3 (Grew and Hinthorne, 1983). Boron appears to
Planar OH-bearing defects in mantle olivine
Olivine, (Mg, Fe)2SiO4, is the predominant mineral in the upper mantle and a study of its defect structure is fundamental to an understanding of the rheological laws that describe mantle flow.
Boron in Sillimanite
Sillimanite in six granulite-facies, kornerupine-bearing rocks contains 0.035 to 0.43 percent B2O3 and 0.23 percent MgO (by weight), which is too low to appreciably affect the stability relations of sillimanite with kyanite and andalusite.

Pressure-Temperature-Time Paths and a Tectonic Model for the Evolution of Granulites
Petrologic studies and application of well-calibrated mineralogic thermometers and barometers reveal several important features common to many granulite terrains: (1) "Peak" metamorphic pressure and
