Chalcopyrite: LL-Cpy

S-Fe-Cu isotope analysis for chalcopyrite

The sulfide samples (Figure 1a-c) in this study were collected from the Linglong golden deposit located in the Jiaodong area in the eastern part of the North China Craton. The deposit is one of the largest quartz vein-type gold deposits in Jiaodong, where the ore formation is mainly controlled by a NNE-NE trending fault zone. Here, the masses of these three massive sulfides are 6.4, 0.7 and 1.0 kg. Pure chalcopyrite fragments were picked and packed, called as LL-Cpy.
