广东省典型铅锌多金属矿床镉的分布特征
DISTRIBUTION CHARACTERISTICS OF CADMIUM IN TYPICAL Pb-Zn POLYMETALLIC DEPOSITS OF GUANGDONG PROVINCE
摘要
Abstract
Exemplified by typical Pb-Zn polymetallic deposits in Guangdong Province, the authors studied the content characteristics of cadmium in various mining areas and the distribution characteristics of the cadmium content and w(Zn)/w( Cd) ratios in sphalerite from different types of ore deposits. The results show that different geochemieal backgrounds in different mining areas have exerted great influences on the enrichment degree of cadmium. In various mining areas, Cd and Zn show correlation or even strong correlation, suggesting that they had similar geochemieal characteristics during the ore-forming process. The superimposition of high cadmium content and low w( Zn)/w( Cd) ratios mainly occurs in the distribution areas of known Pb-Zn polymetallic deposits, and the enrichment degree of cadmium somewhat decreases in all directions. The enrichment coefficient of cadmium and w(Zn)/w( Cd) ratios in sphalerite from different types of ore deposits show obvious ladder-like variations, which were not only controlled by the temperature and color during the ore-forming processes of different types of sphalerite but also closely related to silver enrichment in the mining area. This study provides scientific basis for understanding distribution characteristics of cadmium and making geological evaluation of cadmium deposits in Guangdong Province.关键词
