Mineralogy and trace element geochemistry of the Co- and Cu-bearing sulfides from the Shilu Fe–Co–Cu ore district in Hainan Province of South China

Hosted within the metamorphosed, neritic siliciclastic rocks and sedimentary carbonates of the Proterozoic Shilu Group, the Shilu Fe–Co–Cu ore district in Hainan Province of South China comprises the upper Fe- and the lower Co–Cu ore layers. Combined with the field observation, the mineralogical and geochemical studies of sulfides using electron microprobe and laser ablation ICP-MS analyses recognized three types of Co–Cu ores. Type I is...
