ABSTRACT: İn this study, detailed geology`, mineralogy, alteration ofs karn deposits in Çambaşı (Ordu) and Dereli (Giresun) areas were investigated and compared. In the studied area, two types of exoskarns were identified as garnet-pyroxene and epidote skarns. Mineralogy and mineral chemistry of these skarn zones were investigated. Garnets in Çambaşı (Ordu) skarn deposits are grossular-andradite (GrSfwo 43~^r0.06-0.56^ whereas in the Dereli (Giresun) area pure andradite and grossular-andradite (Adr0 47.0 996^0.0(1-0. $/). The clinopyroxenes in Çambaşı (Ordu) and Dereli (Giresun) areas, are classified as diopside. It was found out that the correlation between the composition of garnets and clinopyroxenes related to metal that skarn contains. The compositional distubution of the garnets and clinopyroxenes in the studied areas display a distribution pattern similar to garnets and clinopyroxenes from world-class Fe-Cu skarn.
