dc.description.abstractMany studies have shown systematic correlations between the composition of plutons worldwide and the metal contents of associated skarns. This is the first report of similar correlations between plutons and the skarns of the Akdagmadeni, Akcakisla, and Keskin districts in Central Anatolia. Herein, die genetic associations of skarn occurrences are investigated using the geochemical compositions of the intrusives. In terms of major- and trace-element data, the granitoids associated with skarns show important differences. Three general groups of plutons, are distinguished, and the distinction among them is based largely on major-element data. In general, the granitoids associated with Pb-Zn skarns in all three districts are classified as subalkaline/calc-alkaline, based on TAS and AFM diagrams, respectively. The Akdagmadeni and Keskin granitoids display S-type characteristics, and those of Akcakisla display I-type characteristics. As a whole, the granitoids in all districts display major-element geochemical characteristics (Harker diagrams) that typify plutons associated with worldwide Zn, W, Mo, and Sn skarns. These data probably indicate that some other elements, like W in the Akdagmadeni district, and Mo + Sn in the Keskin district, could be associated with these skarns. Similarly, the granitoids of Akdagmadeni and Akcakisla have trace-element geochemical signatures (Zr versus Ba and Zr versus Rb/Sr diagrams) that typify plutons associated worldwide with Zn, Cu, Mo, and W skarns. This also helps to underline the possible association of W and Mo skarns in the Akdagmadeni district, and Cu skarns in the Akcakisla district. The average K2O/Na2O ratios of the plutons also serve to differentiate the granitoids associated with different types of skarns. The average K2O/Na2O ratio of the Keskin pluton it; 1.23, close to that of plutons associated with major Mo and Sn skarns. On the other hand, the average K2O/Na2O ratio of Akcakisla granite is very close to 1.0, close to that of plutons associated with major Cu (and W?) as well as Pb and Zn. Therefore, these skarns should be investigated in terms of the potential for those elements. This suggests new exploration possibilities for the Akcakisla, Akdagmadeni, and Keskin districts.
