A new Cr-spinel reference material (BL-SP) for in-situ microanalyses

Key Points

• The central aim is to characterize BL-SP as a reference material for in-situ microanalysis of spinel minerals.
• Evaluated homogeneity of major and trace elements using electron probe techniques.
• Conducted a comprehensive characterization of the BL-SP material.
• Demonstrated that BL-SP has consistent compositions of major and trace elements suitable for microanalysis.
