Abstract :Geostatistical analyses were carried out on 160 rock samplesfor 24 elements from the Div riği iron ore region. The samples were initiaîly treated as one population. Thereafter the indivi dual rock types were divided into several groups and geostatistically analysed. The geostatisti cal methods are described shortly for T'nivariate and Bivariate analyses and, most importantly, the multivariate methods such as Discriminant-, Cluster-, and Factor analyses. The results of the geostatistical analyses yield a division into different rock groups (Discri- minant analysis) and several elementassociation (Cluster-and Factor analyses), which reflect the different rock types. In the individual groups the elementassociation telis ;ore about the geological processes e.g. serpenîinization and hydrothermal aîteration. The difference between Cluster- and Factor analyses is seen in the Faclor analysis, which is a little more differentiated, enahling a more subtIe interpretation of the possible geological environment. The interpretation of the elementassociation suggests that the iron cres are closely associ- ated with mafic to ultramafic rocks, their serpenîinization and aîso later haydrothermal events.Keywords : ÂN ENAMPLE, GEOCHEMICAL, IRON DEPOSiS
