ABSTRACT

The Correspondence Analysis Method (CAM) is actually a Non-structural method that could be used to define the anomaly from the background. To apply this method, representative samples of a large area are necessary but knowing the exact location of each sample is not necessary. Base on this method, the litho-geochemical data would be mathematically process to extract the valuable factors needed to plot a two by two diagram. This method has been applied on available data in Enjerd skarn deposit. Five factors have been calculated by applying this method, which is resulted to a 5 columns final matrix. According to these factors, we could plot variety diagrams, resulting to; the samples No. 21, 28, 19 and 23 for Cu, No. 4, for Zn, No. 22 for Pb, No. 26, 29 and 30 for Co and Ni, show actual anomalies, respectively. In most diagrams Co and Ni are Para genetically related, since they show very clear Co-separation features.
