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 inductively coupled plasma-atomic emission spectrometry (ICP-AES) and ICP-MS with sodium peroxide sinter digestion. Tellurium content was determined by hydride generation atomic absorption spectrometry with multi-acid digestion and hydride generation
