塞尔维亚Mali Krivelj斑岩型铜矿床热液蚀变作用及元素迁移规律
Hydrothermal alteration and elements migration features of Mali Krivelj porphyry copper deposit in Bor metallogenic belt,Serbia
摘要
Abstract
The Mali Krivelj porphyry copper deposit is located in the Bor metallogenic belt in the western segment of the Tethyan metallogenic domain.Typical samples of fresh andesite and rocks in different alteration zones are col-lected for the trace element testing and element mass-balance calculation to research the hydrothermal alteration and elements migration during mineralization.The analytical results show that the phyllic zone and the chlorite-sericite alteration zone have similar elemental migration laws,Sr,Ba,Zr,Th,U,Ti,Co,Ni and REE elements emi-grate in a certain degree,while Rb,Cs and other elements migrate in a certain degree,a large number of magnetite develops in the chlorite-sericite zone,while a large number of quartz + sericite + pyrite occur in the phyllic zone.All of these show that the fluid reducibility gradually increases with the continuous evolution of the fluid.The al-teration in propylitic zone is weak,and the overall elemental migration is not high.Cu has a good positive correla-tion with Cr,Rb,Ti/Sr,Rb/Ba and Cr/Zn,and a certain degree of negative correlation with REE,Ba,Zn,Mn and Sr,which indicates that the whole rock element migration law of porphyry deposits can also be used as geochemi-cal exploration indicators to a certain extent,and provides support for finding porphyry mineralization center.关键词
