Abstract

The KHUT AND PANAH-KUH SKARN deposit is located at about 50 km northwest of Taft in Yazd province. The analyses of major and REE's by microprobe and LA-ICP-MS show that there are two major types of GARNET at Khut and Panah Kuh SKARNs. The GARNETs in the Khut SKARN range from (Ad74.30Gr24.81- d32.06Gr66.61) to almost pure andradite (Adr>96) in composition whereas all Panh-Kuh SKARN GARNETs are almost pure andradite and isotropic. The REE become commonly enriched in GARNETs during metasomatic process. On the Fe/Ti versus Al/ (Al+Fe+Mn) diagrams, these rocks suggests that over 50% of hydrothermal fluid phase has been effective in the formation of GARNETs. Comparison of chondrite- normalized REE patterns GARNETs exhibit that all GARNETs have light REE (LREE) enrichment and heavy REE (HREE) depletion, with different Eu anomalies. Fe-enriched GARNETs are characterized with positive Eu anomaly whereas grandite show negative Eu anomaly. Differences in the magnitude of the anomaly reflect local heterogeneities of the system such as protolith as well as metasomatic fluid. The same abundance pattern of REE in the SKARN and GARNET suggests that GARNET is the most important REE host mineral. Therefore, the study of REE geochemical behavior is benefiial in understanding the evolution of metasomatic fluids.
