Title

PETRO GENESIS OF SKARN RELATED CU-PORPHYRY INTRUSION DEPOSIT, ALI-ABAD- DARREH ZERESHK, YAZD

Pages

  79-92

Abstract

 The study area is a part of Cenozoic magmatic belt of Central Iran, which is located in the West of Yazd porovince. Contact metamorphism and SKARN occurred in conglomerate part of Sngestan Formation. The Oligocene intrusion bodies of Ali-Abad-Darreh Zereshk are leucocerate and have the chemical composition of granite to granodiorite with calc-alkaline affinity from volcanic arc geological setting. The main mineral assemblage of SKARN in order of imprtance is as follow: GARNET+epidote+quartz+calcite + pyrite+iron oxides. Brown GARNETs are the SKARN characteristic mineral. EPMA analysis has shown that the chemical composition with GARNET belong to ANDRADITE-grossular solid-solution (And 65, Gross 30) with more ANDRADITE component. The high permeability and presence of carbonate pebbles in conglomerate are two important factors for fluid flow and genesis of GARNETs. Distinct oscillatory zoning in GARNETs is resulted from the change of fO2 in fluids. The evolution of Ali-Abad SKARN is took place in the range of 380 to 530 oC, 0.5 Kbar pressure and high fO2. Also close association of this SKARN with Ali-Abad intrusive with CU-PORPHYRY mineralization shows that this SKARN is a CU-PORPHYRY type SKARN.
