MOAZZEN Department of Geology, Tabriz University, 29 Bahman Blvd. Tabriz, I. R. of Iran, 51664 Journal Article 2002 06 17 Chloritoid is crystallised with chlorite, white mica and garnet in chlorite zone metapelites of<br />the regional metamorphic rocks of the Sanandaj-Sirjan metamorphic belt in southern Iran. Chemistry of<br />coexisting minerals is studied using microprobe analysis. Application of the chlorite-chloritoid<br />geothermometry gives temperatures of 515°C and 557°C. The Chlorite-garnet Fe-Mg exchange<br />geothermometer indicates temperatures between 442°C and 460°C for various pressures. A comparison<br />of the results from two geothermometers, along with a study of mineral assemblages in the rocks show<br />that the chlorite-chloritoid thermometer overestimates the temperature by about 70°C. https://ijsts.shirazu.ac.ir/article_2835_565c10a8efae58077c565b16fa82e271.pdf
