Garnet genesis in altered conglomerate of Sangestan Formation, Damak Aliabad (west of Taft, Yazd Province)

The conglomerates of Sangestan Formation (Lower Cretaceous) have been metamorphosed in the vicinity of the leucogranitoid rocks of the Shir-Kuh batholith and have created the mineral assemblage of garnet- epidote-quartz-calcite-pyrite in the contact halo. Following the contact metamorphism, hydrothermal alteration (pyrite formation and silicification) has likely occurred. Based on the trace element contents of the garnets, the skarn in the contact halo is Cu-Pb-Zn bearing calcic skarn type. The above mentioned minerals, apparently, indicate that there is a genetic relationship between intrusion related Cu-mineralization and the skarnification in the study area.
