| Description |
43 rock samples from storage were crushed so that 70% of the material passed through a -10 (2 mm) mesh screen. Rock samples were then pulverized so that 85% of the material passed through a -200 (75 micron) mesh screen. Riffle splitters ensured accurate sampling of 30-gram and 200-gram samples. 43 rock samples were analyzed for major and minor oxides using X-Ray Fluorescence Spectrometry following a lithium metaborate fusion. Samples were then analyzed (FA03038304) for trace elements using X-Ray Fluorescence Spectrometry on a pressed powder pellet. |
