17 samples were analyzed by the following methods and digestions: ICP after borate fusion, titrimetric analysis, gravimetric analysis and XRF. 2 samples were analyzed by ICP after HF-HNO3-HClO4 acid digestion with HCl leach and XRF. 6 samples were analyzed by DC Plasma Emission after fire assay and LECO Sulfur analysis. 3 samples were analyzed by INAA with delayed neutron counting. Interference in the results are due to high levels of Ba.
