Abstract: 

The Masjeddaghi area is a part of Alborz-Azarbaijan Zone and located in the Jolfa 1:100000 geological map sheet. The Oldest rock units cropped out widely in the south and northeast of the area belong to the Eocene flysch-type sediments. The Other outcrops consist mainly of volcanic rock complex of andesites and trachyanuesites affected by quartz monzonite Intrusion and caused alteration of phyllic and carbonate phyllic type. The mineralization in volcanic complex is also Accompanied by quartz and barite veins. The study of alterated zone around veins shows sericite, silicified, prophillitic, Chloritic and alunite (jarosite) alterations. Investigation of alteration zones around mineralized veins shows epithermal gold ore in which alunitic alteration (jarocite) is the most important characteristics. The result of the study on alteration and extension of altered zones in the whole study area give rise to the probability of porphyry type copper deposit (potassic. phyllic. argillic and prophylitic alteration zone).
