Discovery of the Hendou-abad copper mineral district and its association to dikes: A reconstruction scenario for exploration of Cu-porphyry, northeast Isfahan, Iran

Abstract The Hendou-abad copper mineral district is located along the eastern margin of the central part of Urumieh–Dokhtar Magmatic Arc (UDMA). The mineralization is hosted in the Late Eocene basaltic andesite and trachybasalt, where it is associated with epidote, calcite, and quartz as alteration minerals, and red, white, and green breccias. Two main events of mineralization with alteration have been distinguished: hypogene and supergene. Abundant parallel dike swarms intrude Late Eocene volcanic rocks of the Henduo-abad. The Hendou-abad dikes are seen as a few cm to 4 m wide and
