| Abstract: | The Yejiwei porphyry tin deposit is a large-scale but low-grade tin deposit with polymetallic association in Dongbo orefield. The deposit is spatially associated with the Yejiwei porphyry offshoot, which exhibits evident altered roock zoning. Tin mineralization occurs in disseminated and veinlet-disseminated forms and is related to certain alteration processes.The Yeijiwei porphyry tin deposit is very similar to the Yinyan porphyry tin deposit in many aspects, such as ore-bearing rock, mineralization and alteration. But these two deposits are different in regional geological setting. Therefore, the discovery of the Yejiwei porphyry tin deport enlarges our thinkings of prospecting for tin deposits in Hercynian-Indocinian depressions in South China, which are characterised by occurrence of cassiterite and polymetallie sulfide. |
