Relating deformation fabrics to multiple metamorphic events preserved in metapelites of the Belt-Purcell supergroup in the Snow Peak area of northern Idaho
… metamorphic and deformation events by studying garnet growth and structural fabrics preserved in the metapelites in the Snow Peak area. All the samples within the M1/D1 affected area have the earlier foliation (S1) as the dominant matrix foliation. S1 in these samples was overprinted by S2 which …

Multidisciplinary analysis of a polymetamorphic terrane, western New England
… at lower Acadian overprinting temperatures. Garnet developed texturally and chemically distinct rims which appear to reflect prograde Acadian metamorphism in higher-grade parts of the Acadian metamorphic zone. Previous studies of garnet zoning have emphasized volume and surface diffusion as …

Metamorfismo varisico dell’Unità tettonica del Monte Grighini,Sardegna centrale
… grade metamorphism evidenced by mineral such garnet, staurolite, andalusite and sillimanite, and by the presence of a syn-kinematic late-Variscan intrusive complex related to a shear zone marked by ultramylonites and cataclasites. Geological map in scale 1:25000 of the Monte Grighini Complex …

Petrologic and Fluid Inclusion Constraints on the Tectonic Evolution of the Manhattan Prong, Southeastern New York
… P-T conditions of 4-5 kbar and 650-700 oC. Garnet porphyroblasts, homogenous with respect to major elements but zoned with respect to P and Y, contain ubiquitous, primary, CO2-rich fluid inclusions which have a Th = 10-24 oC. Manhattan Schist collected adjacent to the Croton Falls and Peach …
