Cd occurrence status and its enrichment characteristics of the sphalerite in lead-zinc deposits,eastern Beihuaiyang district
This paper studied Cd occurrence status and its enrichment characteristics of the sphalerite from the typical lead-zinc deposits in the eastern section of Beihuaiyang district based on the petrographic observation and EPMA analysis.The results show that Cd resource is mainly occurred within sphalerite,with a small a-mount occurring in galena and pyrite.The mass fraction of Cd in sphalerite is negatively related with Zn,in-dicating that Cd replaces Zn in an isomorphic manner and enters the lattice of sphalerite.The statistic results suggest that there is no significant relationship between Cd enrichment in sphalerite grains and their colors.In the eastern Beihuaiyang district,the Cd enrichment of sphalerite in the lead-zinc deposits exhibits a descending trend from the explosive breccia type(Gongdongchong)to the skarn type(Yinshuisi),and then to the low-temperature hydrothermal type(Yinchong)deposits.
