The Saveh-Kashan-Qom copper belt, in the northern part of the Urumieh-Dokhtar Magmatic Arc (UDMA), consists of one of the oldest gold and copper zones in Iran (Samani, 1998; Rajabpour et al., 2017); where the Upper Eocene-Oligocene Mard Abad-Bouin Zahra volcanic suite is situated in this belt. This volcanic suite hosts several copper deposits/occurrences including the Jarou, Gomosh Dash, Ghezel Cheshme, Bidestan and Afshar Abad that are known as "Kuh-e Jarou Mining District". The Kuh-e Jarou Mining District have a total potential ore reserve of 2 Mt Cu with an average grade of 3 wt%. (Zar-Azin Gostar Consultant Engineering Co., 2009). The Upper Eocene volcanic and pyroclastic rocks of rhyodacite, trachyandesite, andesite, and trachytic tuff with high-K calc-alkaline to shoshonitic affinity consist of the main host rocks for Cu mineralization. These units are primarily intruded by the post Eocene intrusive bodies. Since most of the previous studies in this area have been focused on petrology volcanic and intrusive rocks and therefore the geochemistry and genesis of ore bodies have not been fully understood. However, the main purpose of this study is to investigate the mineralization style, geometry, and textural-structural features of orebodies, alterations, and fluid inclusions with an implication for the genesis of the Jarou, Gomosh Dash, Ghezel Cheshme, Bidestan and Afshar Abad copper deposits. In addition, this research provides more insights into the understanding of geology and mineralization conditions in the study area with an implication for the future exploration.
