Tracing post-magmatic processes using large-area multi-element LIBS mapping

Elemental mapping of light (Li, Be, B) and trace elements in largearea geological samples represents an analytical challenge. Increased interest in Li and rare-element deposits showed a need for reliable light element mapping. One of the possible solutions is a laser-induced breakdown spectroscopy (LIBS) combined with sophisticated data processing. We studied four large-area (ca. 8⨯8 cm) samples from two rare- element Be-rich granitic pegmatites with moderate contents of Li (Maršíkov, Czech Republic) and high contents of Li+B (Rau property, Yukon, Canada). Cross-sections from host rock to the pegmatite evolved center were used for direct multi-element mapping and tracing post-magmatic metasomatic and hydrothermal processes.
