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 insert ignore into journalissuearticles values(Discri- minant analysis); and several elementassociation insert ignore into journalissuearticles values(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.
