Meteorite Analysis: STEP 2 EPMA and BSE Analysis

 EPMA & BSE - Electron Probe Micro Analysis and Backscatter Electron Imaging *We highly recommend a preliminary visual (photo) evaluation of a sample prior to submitting it for EPMA & BSE analysis. Many times we can identify common minerals and rock types, saving hundreds of dollars in analysis fees. Please note, most samples are not recommended for EPMA analysis. EPMA - Geochemical analysis of diagnostic elemental ratios within specific mineral grains. BSE - Petrographic analysis of mineral modal abundances, texture, and other petrological characteristics.  SAMPLE REQUIREMENTS, PROCESS & CONDITIONS OF ACCEPTANCE Send Geo Labs a representative sample of approximately 1 inch x 1 inch (25mm x 25mm) with a thickness of at least 1/8 inch (3-4mm). This  sample does not include, and will not be counted towards the 20 grams or 20% (whichever is less) donation sample amount required by Nomenclature Committee. See: donation requirements for submission and official approval. Sampl
