Resumen
Laser Induced Breakdown Spectroscopy (LIBS) and Laser Ablation Inductively Coupled Plasma-Mass
Spectrometry (LA-ICP-MS) are used simultaneously for spatially resolved mapping of major and trace
elements and isotopes within a Bastnasite ¨ rare earth ore sample. The combination of the two techniques
provides complementary measurements for elements that are separately unattainable due to low
sensitivity and/or strong interferences. Two dimensional (2D) layer-by-layer mapping, 2D cross-sectional
imaging and three-dimensional (3D) volume rendering of elements and isotopes in the Bastnasite ¨ matrix
are presented. These results pave the way for improved 3D elemental imaging through simultaneously
acquired LIBS and LA-ICP-MS measurements.
