Chalcopyrites: JGZ-78

Cu isotope analysis for chalcopyrites

The chalcopyrite JGZ-78 is collected from Jiguanzui copper-gold deposit at Hubei Province, China, in the middle and lower Yangtze metallogenic belt. The main metallic minerals are chalcopyrite and pyrite which are eutectoid to semi-euhedral crystals that are symbiotic with calcite.
