| Description |
25 samples were prepped by crushing and pulverizing. 25 samples were analyzed for major, minor oxides and trace elements by the following methods and digestions: for major oxides by XRF after lithium tetraborate fusion; titrimetric analysis for FeO and gravimetric analysis for LOI; trace elements by XRF after pressed pellet preparation. Fe2O3 % is calculated. The same 25 samples were also analyzed for trace elements by the following methods and digestions: NAA, ICP after HCl:HNO3 (3:1) acid digestion, ICP after NaOH fusion, ICP after Multi-Acid digestion, DC Plasma Emission after fire assay, DC Plasma Emission and XRF after pressed pellet preparation. |
