Summary

66 stream sediment samples were assayed for gold by inductively coupled plasma-mass spectrometry (ICP-MS) following Aqua-Regia digestion. Trace element geochemical analyses were performed by ICPMS methods after four-acid, near-total digestion. Digestion involved heating a 0.25 g split in HNO3-HClO4-HF to fuming and then taking it to dryness. The residue was dissolved in HCl. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for theseelements. In addition, some loss of certain elements may result from volatilization during fuming. See publication for a listing of these elements.
