Microanalysis

Interdisciplinary, multi-scale integration of microanalytical methods Source: BGR

The exploration of mineral resources relies on the application of state-of-the-art analytics and the development of novel, rapid methods for the exploration of critical resources in rocks and residues across various scales, from satellite imagery to the sub-microscopic realm. The utilization of individual methods occurs in an interdisciplinary and multi-scale approach.

• Imaging Techniques

  Contemporary scanning methods such as µRFA, LIBS, SEM-based MLA, Raman, Kathodolumineszenz, hot cathode cathodoluminescence microscopy, and hyperspectral imaging provide highly spatially resolved chemical/mineralogical overview and detailed data. These methods are relevant for many geological inquiries related to ore deposit exploration.

• Quantitative Methods
  Selected samples are examined with high precision through microanalytical techniques such as microprobe analysis, Raman spectroscopy, LA-ICP-MS, FEG-SEM and fluid inclusion microthermometry using a heating/cooling stage to address questions pertaining to mineralogy, mineral chemistry, compositions of fluid inclusions in minerals, isotope distribution, and high-tech metal potential, as well as to clarify aspects of genesis, origin, and age of geological samples.
