Mapping mineralogy & textures at the micron-scale to reveal Earth's geological history

Geoscientists have been examining and describing rocks for over 150 years, ever since the advent of light microscopes and petrographic thin-sections in the 1850's. The goal today remains much the same. By making detailed observations of a rock's mineralogy and microstructure, it is possible to unravel its history. However, with the advent of advanced geochemical methodologies becoming more mainstream in petrological studies (such as isotopic  and trace element analysis ), the power of petrography to reveal features of interest is often overlooked. Furthermore, learning to identify minerals optically takes time and considerable practice. However, with our automated mineralogy solutions, geoscientsists can now efficiently, objectively, and quantitatively map materials.

New insights into precious metal enrichment on the Isle of Rum, Scotland
A new study of the Rum Layered Suite (NW Scotland)  shows that the ∼2 mm thick chromitite seams host significant platinum-group element (PGE) enrichment (e.g. ∼2 ppm Pt) and likely formed in situ, i.e. at the crystal mush-magma interface. Full story

About Geoscience

The Earth is made up of different materials - mineral, animal and vegetable. Within the inorganic world (mineral), there is considerable variation - more than 4,000 different minerals are known to occur naturally, which combine in various ways to form 3 main rock groups (igneous, sedimentary, and metamorphic), which in turn give rise to hundreds of different rock types, all of which need to be described, identified and quantified by geoscientists for various purposes (scientific and commercial).  

Thermo Fisher Scientific Solutions for Geoscience

Our automated mineralogy solutions allow geoscientists to quickly and objectively create digital mineral and texture maps of rocks, soil, sediment and man-made materials using fully intergrated scanning electron microscope (SEM) based technology, in combination with energy dispersive spectrometry (EDS)  and advanced image analysis. This new methodology has changed the way we look at earth materials, and is driving advancements in the field of petrology.
