From remote to intimate sensing of minerals and rocks

GeMMe – Minerals Engineering, Materials & Environment
Accurate geological and mineralogical mapping is of paramount importance to environmental and exploration geosciences. Traditionally, these roles are assigned to skilled geologists relying on unaided vision but excellent understanding of the mineral world.
In order for satellites or computer assisted vision technologies to supplement the professional with reliable information, it is important that mineralogical / lithological mapping be based on a sound understanding of optical principles and on calibrated image acquisition strategies.
Through several examples in remote sensing, core scanning, ornamental stone quality control, particle sizing and modal analysis of ores, this seminar tries to emphasize how important vision technologies are for modern exploration geologists, mining and mineral processing engineers.
A special attention will be dedicated to multispectral and/or multiradial imaging techniques with applications ranging from borate exploration in the Bolivian Sud Lipez province down to mineral mapping in carbonate rocks.
Last but not least, the mathematical tools available for proper size and shape description of geological objects as well as the principle of rose of intercepts for texture analysis will be illustrated with a glimpse into the 3D world.
