Publication Top Notes:

1. Mixing properties of aluminosilicate garnets: constraints from natural and experimental data, and applications to geothermo-barometry

Authors: J. Ganguly, S.K. Saxena
Journal: American Mineralogist, Vol. 69(1-2), pp. 88–97, 1984
Citations: 725
Summary:
This seminal work investigates the mixing properties of aluminosilicate garnet solid solutions using both natural and experimental data. Ganguly and Saxena developed thermodynamic models for the mixing behavior of garnets in the pyrope-almandine-grossular system. The study provided key constraints for the use of garnet as a geothermobarometer—a tool for estimating pressure and temperature conditions of rock formation—thereby advancing petrologic modeling and metamorphic studies.


2. Thermodynamics of aluminosilicate garnet solid solution: new experimental data, an optimized model, and thermometric applications

Authors: J. Ganguly, W. Cheng, M. Tirone

Citations: 452
Summary:
This paper presents new experimental data and an improved thermodynamic model for aluminosilicate garnet solid solutions. By refining activity-composition relations, the authors developed a more accurate method for garnet-based thermometry. The model has found widespread application in metamorphic petrology, allowing for more precise temperature estimations in high-grade metamorphic rocks.

Authors: Hany Lee, J. Ganguly
Journal: Journal of Petrology, Vol. 29(1), pp. 93–113, 1988
Citations: 439
Summary:
This study experimentally determines equilibrium compositions of garnet and orthopyroxene in the Fe-Mg-Al-Si-O system at high temperatures and pressures. The resulting thermodynamic data have been used to calibrate geothermometers and geobarometers, facilitating better interpretations of metamorphic conditions in ultramafic and mafic rocks. The work is foundational in linking mineral compositions with metamorphic P-T paths.

Authors: S. Chakraborty, J. Ganguly
Journal: Contributions to Mineralogy and Petrology, Vol. 111(1), pp. 74–86, 1992
Citations: 386
Summary:
This research focuses on the diffusion behavior of cations (notably Fe and Mn) in garnet minerals using diffusion couples of spessartine and almandine. The study provided essential diffusion coefficients and insights into the time scales of metamorphic processes. These findings are pivotal for understanding compositional zoning in garnets and for modeling the kinetics of mineral reactions.

Authors: K. Bose, J. Ganguly
Journal: American Mineralogist, Vol. 80(3-4), pp. 231–238, 1995
Citations: 373
Summary:
This paper revisits the quartz–coesite phase transition through a series of reversed experiments at various temperatures. The authors refined the equilibrium boundary and derived updated thermochemical data, which are crucial for understanding ultrahigh-pressure metamorphic conditions. This work significantly contributed to the identification of coesite as an indicator of extreme metamorphic environments, such as those found in subduction zones.
