Abstract

Introduction: Determination of the background limit and separating anomalies from the background is very important in geochemical data analysis. This is more important for data which are collected from stream sediments samples. Nowadays, one of modern technique for separating anomalies from background is FRACTAL METHODs. This is very useful and suitable for separating data distribution due to their spatial distribution and anomalies geometrical features. Concentration-perimeter method is very useful and high level confidence for separating of geochemical societies, especially in stream sediments data.Aim: In this study, background and anomalies were separated for Cu, Au, Mo, Ag and As in ZAJKAN area from TAROM in Zanjan province.Material and Method: First, 84 stream sediments samples were collected from the area and these were chemical analysis. Also, single and two variation statistical parameters were calculated. Next, based on the results area was grided and grades evaluated were done for these elements by grid evaluation method especially stream sediments. Then, Concentration-perimeter logarithmic diagrams were drawn for these elements and geochemical societies were separated. Finally, elements distribution maps were drawn in the area and their results were comprised by classical statistics and coefficient correlations.Results: Results from usage of fractal CONCENTRATION- PERIMETER model shows that proved anomalies areas of these elements are situated in central and eastern parts of ZAJKAN.Conclusion: The comparison shows that fractal CONCENTRATION- PERIMETER model is better than classical statistics.
