ABSTBACT: Similar features exhibited by numbers of skarn zones is thought to be a reflection mi thesimilarities of the conditions operated during the skarn formation. Studes on varlDn« skarn reveal that ikarnproducing metasomattc transport can be of diffusion or infiltration types. Skarn zones mî Uludaf in view of thecondition of formation and the tMctaaem that they are exMbi^g» the difusion mechanism Is thought to beeffective in endoskarns development. The exoskarns, however, are the product of infîltratîon controlledmetasomattc transport, and the zonation within exoskarn is believed to be the result of the selective precipitationdue to pH variation from the plutonfo body towards the marbles of Uludağ,
