Mesozoic sandstone-type copper deposit in Central Yunnan region is of zoning order of chalcocite-bornite-chalcopyrite-pyrite. The classical theory suggests that such a sequence of sub-zoning is mainly controlled by the Eh value. Theoretical analysis is consistent with the analysis of the cement component in practical mineral zoning, namely the mineral is rich in alkaline cement(carbonate cement), which is significant for the future prospecting in Dayao copper deposit.
