| Description | Igneous and meta-igneous rocks showing little alteration or weathering were collected for major-oxide, minor-oxide, and trace-element analyses to determine bulk rock composition of igneous and meta-igneous lithologies, or to identify the tectonic setting of a sample's protolith from petrogenetically important trace elements. These samples were prepared by ALS Minerals in accordance with their PREP-31 package which involves crushing the entire sample to less than 70 percent passing -10 mesh (2 mm), then splitting off 250 grams and pulverizing the split to better than 85 percent passing 75 microns. A prepared sample (0.200 g) is added to lithium metaborate flux (0.90 g), mixed well and fused in a furnace at 1000 degrees Celsius. The resulting melt is then cooled and dissolved in 100 mL of 4% HNO3 / 2% HCl3 solution. This solution is then analyzed by inductively coupled plasma - mass spectrometry. |

A calcined or ignited sample (0.9 g) is added to 9.0g of Lithium Borate Flux (50% - 50% Li2 B4 O7 - LiBO2), mixed well and fused in an auto fluxer between 1050 - 1100 degrees Celsius. A flat molten glass disc is prepared from the resulting melt. This disc is then analyzed by X-ray fluorescence spectrometry. |
