Mineral Mapping Research

  • Research at the Core-Net facility focuses on remote sampling techniques that maximize the power of this technology, benefitting research and industry in practical ways.
Drill core

Mineral mapping selected elements

Absorption features evaluated
Drill core analyzed for mineral features.

Depth profile: (a) The wavelength position of the largest absorption feature between 850-970 nm compared to the whole rock geochemistry results for (b) iron, (c) copper, and (d) sulfur. (e) The intensity of the largest spectral feature between 2190-2230 nm compared to the whole rock geochemistry results for (f) aluminium, and (g) potassium.

Relationship between the calculations performed on the absorption features and the results from the geochemical analysis.


Automated drill core scanning spectrometers have been shown to be capable of "rapidly collecting compositional data from the surface of drill core, and these datasets can provide compositional data at a much higher spatial resolution (e.g. every 8 mms) than traditional geochemical techniques (e.g. every 2.5 or 5 meters)." (Tappert et al 2010)
