Gold, Pt, and Pd content were determined in geologic materials by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) after collection by fire assay. Fifty-five major (except Si and Na), rare-earth, and trace elements were determined in geologic materials by using a sodium-peroxide sinter digestion followed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and ICP-MS. Tellurium content was determined using multi-acid digestion and hydride generation/hydride generation atomic absorption spectrometry. Niobium, Th, and Zr were determined by wavelength dispersive X-ray fluorescence spectrometry when the results from analysis by ICP-AES and ICP-MS were higher than the upper detection limit of the method.
