Slab XRF analysis - The XRF analyses were run on a PANalytical Axios spectrometer using SuperQ software. Nb, Rb, Sr, Y, and Zr were measured using Super's 37mmRbSrYZr routine software program; other elements were measured with the IQ+37mmVac software program. The 37mmRbSrYZr routine uses specific pre-determined peak and background positions for which x-ray intensities are measured for 2-800 seconds (depending on the element). The intensity of the Rh Compton peak is used to estimate mass-absorption coefficients (MACs) for both unknowns and well-characterized natural standards. Peak intensities are computed and converted to concentrations using calibration curves employing at least 10 natural rock standards.

A calcined or ignited sample (0.9 g) is added to 9.0g of Lithium Borate Flux (50% - 50% Li2 B4 O7 - LiBO2), mixed well and fused in an auto fluxer between 1050 - 1100 degrees Celsius. A flat molten glass disc is prepared from the resulting melt. This disc is then analyzed by X-ray fluorescence spectrometry.

A prepared sample (0.200 g) is added to lithium metaborate flux (0.90 g), mixed well and fused in a furnace at 1000 degrees Celsius. The resulting melt is then cooled and dissolved in 100 mL of 4% HNO3 / 2% HCl3 solution. This solution is then analyzed by inductively coupled plasma - mass spectrometry.

Nb, Rb, Sr, Y, and Zr were measured using SuperQ 37mmRbSrYZr routine software program; other elements were measured with the IQ+37mmVac software program. The 37mmRbSrYZr routine uses specific predetermined peak and background positions for which X-Ray intensities are measured for 2-800 seconds (depending on the element). The intensity of the RhCompton peak is used to estimate mass-absorption coefficients (MACs) for both unknowns and well-characterized natural standards. Peak intensities are computed and converted to concentrations using calibration curves employing at least ten natural rock standards. Note: the reported values may...

Typical analysis for rocks and sediments was a 1.1 oz (31 g) gold-platinum-palladium fire assay, followed by a 50 element aqua-regia digestion, and a combination of induced coupled plasma-mass spectroscopy (ICP-MS) and ultra trace induced coupled plasma-atomic emission spectroscopy (ICP-AES)analysis. These analyses were followed by pressed pellet X-ray fluorescence spectroscopy (XRF) analysis for barite, tin, and tungsten. Samples with assay results exceeding element-specific detection limits for the standard analysis were reanalyzed by a variety of element-specific procedures.
