Research Of Distribution Law Between The Cu And Its Associated Au‐Ag‐Re‐Co Elements In Fujiawu Dexingcopper (Molybdenum) Deposit

The paper taked Fujiawu Cu(Mo)deposit as the research object,Through collect geochemical profile data and Use ICP-MS test the trace elements and Au,Ag in Dexing Fujiawu porphyry Cu deposit, and use PIMA technology to determine the alteration zone, then study dilution and enrichment characteristic of trace elements with enhanced Cu mineralization present and the relationship between the main ore-forming elements with the trace elements in the alteration belt, and analyse themetallogenic elements combination. Research shows that,Fujiawu Cu(Mo)Deposit of granodiorite Porphyry and phyllite enrich Cu、Pb、Bi、 Sb、Au、Ag、W、Mo、Re、Cs,deplete Zn、Sc、radioactive elements and rare earth elements,Cd、In、Ga、Tl、Ba、Sr、Sc 、Rb、Be、V、Ni showed both dilution and enrichment,while Co mainly enrich in phyllite,deplete in granodiorite porphyry,Cr and Co showed an opposite trend;Re mainly occurs in the rock mass near the contact zone,Occurrence of Co is associated with middle-weak alteration belt outside of the porphyry body contact zone, Au mainly enriched in the outside belt of rock mass contact zone, Ag have higher enrichment inside and outside the contact zone of rock mass. Factor analysis shows that Cu-Ag-Zn-In、Er-Y-Ce-Pr-Ho-Eu-Gd-Tm-Dy-Y-La-Nd-Tb-Sm-Lu-Re-Mo-Cd-U、Co-Ni and |Au|-W are related to mineralization..Through the research,not only can enrich and rich porphyry Cu(Mo) ore deposit geochemical exploration methods. and provide theoretical guidance for mining area comprehensive utilization of associated(with) elements.
