| Description |
60 rock samples were crushed so that at least 70 percent of the material passed through a -10 (2 mm) mesh screen. 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 60 rock samples were analyzed for major and minor oxides using X-ray Fluorescence Spectroscopy following a lithium tetraborate fusion. 60 rock samples were analyzed for trace elements using X-ray Fluorescence Spectroscopy on a pressed powder pellet. Cerium was analyzed using Inductively Coupled Plasma - Mass Spectroscopy after lithium metaborate fusion. |
