chloritoid is crystallised with chlorite, white mica and garnet in chlorite zone metapelites ofthe regional metamorphic rocks of the sanandaj-sirjan metamorphic belt in southern iran. chemistry ofcoexisting minerals is studied using microprobe analysis. application of the chlorite-chloritoidgeothermometry gives temperatures of 515°c and 557°c. the chlorite-garnet fe-mg exchangegeothermometer in...

Pichagchi pluton is situated in the northeastern part of the Soursat complex in Sanandaj-Sirjan metamorphic belt of Iran. The pluton with the age of 74.20 Ma is composed mainly granodiorite, diorite, and tonalite in which mafic minerals are biotite and amphibole. In this study, composition of minerals used to describe the nature of the granitic magma and estimate the pressure and temperature at...

marbles containing high-pressure mineral assemblage was found from the sanandaj-sirjan metamorphic belt in the nahavand area in western iran.  the high-pressure marbles occur as small bodies or lenses within pelitic schist layers and show compositional banding of carbonate- and silicate- rich bands.  textural analysis revealed two metamorphic stages.  the early stage is testified by relicts of ...

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...
