Mapping Ni-Cu (PGE) bearing ultramafic rocks and associated gossans with airborne and simulated EnMAP satellite hyperspectral imagery, Nunavik, CANADA
This study investigates the use of AISA optical airborne hyperspectral (2 m spatial resolution) and simulated satellite EnMAP (30 m) to produce detailed lithologic maps in a subarctic region (Nunavik, Canada) where ultramafic rock units associated with Ni-Cu-(PGE) mineralization are exposed in the p...
