摘要
Banchang Cu deposit locates inside eastern Qinling orogenic zone,and most exposure strata are spilite of Erlangping group and marble of Qinling group.The ore bodies are distributed in bands on the surface,and ore bodies that point upward occur repeatedly in layers,stratoid structure and imbricate arrangement.The correlation between ore body and wall rock is gradual transition,and the ore bed spreads with ore-bearing silicolite.It shows that the partition curves of mineralized strata,mineralized silicolite,non-mineralized silicolite and non-mineralized marble are similar to each other in light of the partition diagram of 24 microelements.It is also discovered that the result of ribbon carbonatite δ18O in silicolite is 18.809‰~21.572‰,and the result is similar to submarine sedimentation-exhalation.According to the analysis,the authors believe that the genesis of Banchang Cu polymetallic sulphide deposit is a submarine sedimentation-exhalation metal sulphides deposit.
