| Description |
72 rock samples were crushed so that 70% of the material passed through a -10 (2 mm) mesh screen. Representative aliquots of 200 grams and 30 grams each were taken using a stainless steel riffle splitter. Rock samples were then pulverized so that 85% of the material passed through a -200 (75 micron) mesh screen. 72 rock samples were analyzed for major and minor oxides using X-ray Fluorescence Spectrometry following a lithium metaborate fusion. 72 rock samples were analyzed for trace elements using X-ray Fluorescence Spectrometry on a pressed powder pellet. |
