Cation Exchange Between Piemontite and Garnet in Piemontite-Quartz Schists from Asemi-Gawa Area of Central Shikoku, Sanbagawa Metamorphic Belt, Japan
In the Asemi-gawa area of intermediate high-pressure and low-temperature Sanbagawa metamorphic belt in central Shikoku, Japan, piemontite-quartz schists are common in which cation exchange between piemontite and garnet has been studied. Piemontite in contact with garnet usually contains two zones in which core is enriched in Mn3+ and surrounded by a rim rich in Fe3+. Garnet is Ca-Fe-bearing spe...

متن کاملA Detailed Study of Morphology and Chemistry of Garnet Crystals with Suggestion of New Subdivisions: Data from Pelitic Schists, Hornfelses and Aplites of Hamedan Region, Iran
The study area is a part of the Sanandaj-Sirjan metamorphic belt comprising lowto high-grade regional and contact metamorphic rocks that are intruded by various plutonic bodies. Garnet crystals are abundant in pelitic schists, amphibole schists, migmatites, hornfelses and aplites. They are mostly almandinerich (XAlm>60) pyralspite garnets and show dodecahedron, trapezohedron and mixed (dodecahe...

15 صفحه اولA study of various occurrences of the Al2SiO5 polymorphs in the rocks/veins of the Hamedan region, Iran: with special reference to origin of quartz-kyanite veins
The study area is a part of so-called Sanandaj-Sirjan zone or Zagros imbricate zone of the Zagros Orogen, Iran. The Hamedan region comprises a metamorphic sequence of low- to high-grade regional and contact metamorphic rocks intruded by mafic, intermediate and felsic plutonic bodies. The sequence comprises pelitic, psammitic, mafic, calc-pelitic and calc-silicate rocks. Pelitic rocks are the m...
