THE METHODS OF CHOOSING INDICATOR ELEMENTS IN GOLD DEPOSITS SURVEY OF KUANDIAN

In this paper, the authors have intro duced some methods of choosing indicator elements in undiscovered gold deposit area of kuandian county. According to the known geochemical theory of gold deposit and geochemical data of gold deposit in metallogenic belt, the authors primarily elect the indica to relements as the project of chemical analysis. In the process of drafting geochemical map, we use the variation character and metallogenic feature of elements to choose so meelements with obvious variation character and higher metallog enic feature. Based on the above, we use statistical and spatial correlations among elements to reserve those elements with obvious correlation to Auelement as the optimum choosed indicator elements.
