  A visible and near infrared (VNIR) to shortwave infrared (SWIR) hyperspectral
dataset of the Early Archaean North Pole Dome, Pilbara Craton, Western
Australia, has been analysed for indications of hydrothermal alteration.
Occurrence maps of hydrothermal alteration minerals were produced. It was found
that using a spatial resolution on the ground of approximately 5 m and spectral
coverage from 0.4 to 2.5 mm was sufficient to delineate several hydrothermal
alteration zones and associated veins, including phyllic, serpentinitic and
chloritic alteration. These results suggest this level of spectral and spatial
resolution would be ideal for localising shallow epithermal activity, should
such activity have existed, on the surface of Mars.
