| Description |
53 rock samples were crushed with a Terminator jaw crusher with chrome steel alloy plates so that at least 70 percent 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. These samples were then pulverized in a chrome steel ring mill so that 85 percent of the sample passed through a -200 (75 micron) mesh screen. Most trace-element analyses were performed on the 200 gram split. 51 rock samples were analyzed for major and minor oxides using X-ray Fluorescence Spectrometry following a lithium metaborate fusion. 51 rock samples were analyzed for trace elements using Inductively Coupled Plasma - Mass Spectroscopy after lithium metaborate fusion. |
