Correlative Raman-SEM and Atomic Force Microscopy in Geoscience 

Confocal Raman Imaging, Correlative Raman-SEM and Atomic Force Microscopy in Geoscience

Raman spectroscopy has long been applied in geoscience, for example for the identifcation and characterisation of minerals, or in the observation of mineral phase transitions in high and ultra-high pressure/temperature experiments. In most cases, measurements have been carried out with a micro-Raman setup delivering few details of the spatial distribution of components, mineral phases or chemical variations. By using Confocal Raman Imaging (CRI), such characteristics can be rapidly evaluated over much larger areas.
