Abstract: The latest K-Ar, 87Sr/86Sr, and REE data for samples from Sasa-Toranica ore district are presented. Whole rock XRF analyses confirm host rock composition as dacites, quartz-latites, trachyandesites and rhyolites. K-Ar absolute ages range from 31 to 14 Ma confirming Oligocene-Miocene age as previously determined by relative methods. 87Sr/86Sr ratios (0.70954 to 0.71126) suggest material is sourced from the contact zone between the lower crust and upper mantle where contamination of primary melt occured. New REE data including negative Eu anomalies along with previously determined La/Yb ratios ranging from 13.3 to 43.0 (Serafimovski 1990) confirm inferred material source. These new data reconfirm previous results, provide insight into the Tertiary magmatic history of the district, and suggest the exact origin of the material that produced the Tertiary magmatic rocks.
