Highlights

Recently，the exploration of cobalt resources in the Jingchong-Beishan area，the east of Changsha-Pingjiang fault zone，northeastern Hunan Province，has made great advances.Some Co （-polymetallic） vein deposits including the medium-size Jingchong Cu-Co polymetallic deposit and Hengdong Co-Cu deposit，and Dayan Au-Co occurrence were discovered in this region.Based on the detailed field observation，this study identified the ore stages，and concluded the metallogenic characteristics of Changsha-Pingjiang cobalt ore belt as well as the ore-forming factors.The combined microscopic observation and in-situ analytical methods revealed that the metal Co was mainly incorporated in fine-grained pyrite and arsenopyrite as stoichiometric substitution，with subordinate occurrence as independent mineral cobaltite.The complicated texture and chemical compositions of Co-beating pyrite and arsenopyrite indicated that pyrite associated with arsenopyrite has the higher Co concentration （up to 13.48%），greater than that in arsenopyrite-exclusive assemblages.Therefore，the mineral assemblage of fine-grained pyrite and arsenopyrite can be used as the mineral fingerprint to trace the high-grade Co ores during the prospecting exploration.Subsequently，the preliminary mineral processing technology was proposed.
