54 samples were analyzed for trace elements using Instrumental Nuetron Activation Analysis. Samples that were 4 grams or greater were analyzed for tin using X-ray Fluorescence Spectroscopy after pressed pellet preparation. Samples whose weight was undersized were qualitatively analyzed by XRF and if a strong tin signal was detected, the sample was fused into a lithium tetraborate disk and analyzed quantitatively by XRF. If the qualitative results showed little or no tin present, the samples were pulverized and quantitatively analyzed by Optical Emission Spectroscopy. Detection limits raised due to sample size and composition. Tin noted at 100 ppm shows tin present but error is high due to sample size. Variable detection limits due [...]
