Metallogeny of the Neo-Tethys arc in central Iran

摘要

Cenozoic closure of the Neo-Tethys oceans between Arabia and Eurasia resulted in the colli-sional juxtaposition of several small microcontinental blocks separated by ophiolite-bearing suture zones in central Iran. Pre-collisional Eocene-Miocene subduction-related magmatism is best developed in the Uru-mieh-Dokhtar belt along the northern margin of Neo-Tethys II, and several large porphyry copper deposits are located in this belt. Syn- or post-collisional alkalic magmatism scattered throughout the orogen offers potential for epithermal gold mineralization.
