The 29Si MAS NMR spectra of nine pyrope-grossular garnet solid solutions were recorded along with their mid and far infrared spectra. The 29SiMAS NMR spectra ofpyrope and grossular measured previously show one single resonance at -72.0 and -83.9 ppm, respectively. A maximum of up to 13 resonances were observed in composition PYsoGrso indicating that 29Si MAS NMR spectroscopy can record both first and second shell dodecahedral interactions in garnet. Complete resonance assignments were done by…

Grossular: A crystal-chemical, calorimetric, and thermodynamic study

Abstract In spite of the amount of research that has been done on grossular, Ca3Al2Si3O12, there is still uncertainty regarding its exact thermodynamic properties. Because of insufficient sample

Correlations between Garnet Species and Vibration Spectroscopy: Isomorphous Substitution Implications

Excess mixing volume, microstrain, and stability of pyrope-grossular garnets

Abstract Synchrotron X-ray diffraction (XRD) was used to measure the unit-cell parameters of synthetic pyrope (Mg3Al2Si3O12), grossular (Ca3Al2Si3O12), and four intermediate garnet solid solutions.

Prevalence and origin of birefringence in 48 garnets from the pyrope-almandine-grossularite-spessartine quaternary

ABstract Forty garnets are anisotropic among 48 in a suite spanning the quaternary system Mg3Al2Si3O12-Fe3Al2Si3O12-Ca3Al2Si3O12-Mn3Al2Si3O12 (Py-Al-Gr-Sp). The eight isotropic specimens are too thin

Structural investigation of pyrope garnet using temperature-dependent FTIR and 29 Si and 27 Al MAS NMR spectroscopy

Pyrpe garnet, Mg 3 Al 2 Si 3 O 12 , has a relatively large third-law entropy that is thought to be strongly influenced by the structural environment and the motion of Mg in the dodecahedral site.
