Chalcopyrite: 14ZJ12-1

Cu isotope analysis for chalcopyrites

The natural chalcopyrite 14ZJ12-1 is collected from Xiaseling Cu-W deposit at Linan County, Zhejiang Province, China. The main metallic minerals in the quartz-vein are wolframite, chalcopyrite, pyrite, etc. which are eutectoid to semi-euhedral crystals. The chalcopyrite JGZ-29 and JGZ-78 are 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.
