Abstract:
Volcanogenic massive sulfide deposits occur widely in the ophiolite of the Erlangping Group of the Eastern Qinling Mountains. Early to late stage volcanic evolution resulted in the formation of iron formations, sulfide deposits and pyrite mineralization beds. The sulfide deposits have the stratabound nature and show zoning controlled by different distances from the eruption center. Moreover, there are metallogenetic specializations of thick bedded basic lava hosted iron deposits and acid volcanic rock hosted copper zinc deposits or lead zinc copper deposits. The deposits also contain gold silver mineralization.
