Abstract

Hormuz series in Zendan salt dome, Neoprotozoic-Early Cambrian rocks is located near Bandar-e-Lengeh in western Hormozgan Province. In this salt dome, iron calcic skarns are present near the basic igneous bodies that have copper hydrothermal deposits. Carbonate sedimentary sequences, carbonate tuffs and igneous rocks are the host rocks of these skarns. The calcsilicates in the endoskarn include grandite garnets, feldspars, clinozoicite/epidotes, actinolite, wollastonite and vesuvanite. The calcsilicates in exoskarns are garnets and is mostly andradite, epidote, actinolite and wollastonite. Based on microprobe analysis, the type of garnet within skarn varies from And30Gross70 to And100Gross0. Based on crystal chemistry study, the elements such as Zn, Mn, Cu in exoskarns and endoskarns have a systematicaly distribution. Fluid inclusions study of the andradite mineral have indicated that Zendan skarns are formed at temperatures of 600 to 650°C.
