XCT scanning coupled to mineralogy and chemistry on drill cores from LCT-type granitic pegmatites at Bergby, central Sweden

Key Points

• Investigate the application of XCT scanning to analyze minerals in LCT-type granitic pegmatites.
• Utilized 3D XCT scanning for pegmatite core analysis
• Applied attenuation segmentation for quantifying spodumene and petalite
• Compared XCT-derived lithium estimates to bulk ICP-MS assay results
• XCT scanning effectively quantifies spodumene and petalite volumes in drill cores
• Li2 O estimates from XCT show a strong correlation with bulk ICP-MS assays (R2 = 0.75)
