黔西北地区铅锌矿硫同位素特征研究

Study on the Sulfur Isotopic Compositions of Lead-Zinc Deposits in Northwestern Guizhou Province

通过对黔西北地区铅锌矿中硫化物硫同位素的分析表明,各铅锌矿床具有硫同位素组成较为均一,但水城与赫章地区硫同位素组成差异显著的特点。综合分析认为,区内铅锌矿床中的硫可能主要来源于含矿围岩之外的多个膏盐层。

Sulfur isotopic compositions of sulfide minerals of lead- zinc deposits in northwestern Guizhou Province were analyzed. The analytical results indicate that the sulfur isotopic compositions are relatively homogeneous in the same ore deposits. However, the sulfur isotopic compositions in Shuicheng are distinct from those in Hezhang. It is suggested through integrated study that the sulfur of lead- zinc deposits in northwestern Guizhou Province was possibly derived several gypsum- bearing strata except for lead- zinc deposits host - rock.
