THE APPLICATION OF R-FACTOR ANALYSIS TO THE ORIGIN OF METALLOGENIC MATERIALS:A CASE STUDY FOR LUZIYUAN Pb-Zn POLYMETALLIC DEPOSIT OF ZHENKANG,YUNNAN

This thesis researches combinations,changes and distributions relations among elements,samples and geological objects in space and time by R-factor analysis,which provides the basis for discussing metallogenic material source and genesis of deposit.On the basis of researching the geological characteristics of Luziyuan Pb-Zn deposit of Zhenkang,Yunnan,the R-cluster analysis and R-factor analysis has been applied to discuss trace elements of fault rocks in theⅠ,Ⅱ ore-zones for levels 1350and 1220.The results demonstrate that the deposit is strictly controlled by structure,the ore-forming process of the deposit is characterized by multi-period and multi-stage.The ore-forming fluid is mainly originated from the deep hydrothermal fluid and partly derived from the ore-bearing strata(∈3s2,∈3s3).Luziyuan Pb-Zn deposit is a hydrothermal filling and skarn-type Pb-Zn polymetallic deposit controlled by tectonics.
