| Abstract | Airborne hyperspectral methods have been shown to be highly effective for geological mapping and mineral exploration. However, the majority of research and development has occurred in areas of little to
no vegetation cover, typical of hot, arid environments with abundant outcrop and/or regolith. There are fewer case-studies in the public domain that demonstrate the usefulness of hyperspectral remote sensing for the unique geographic and climatic
conditions of Canada's North, exemplified by cold temperatures, minimal surface weathering, minimal vegetation cover, and variable lichen cover.
This talk summarizes hyperspectral research and development activities at Natural Resources Canada
for geological mapping and exploration in Canada's North over the last 10 years. A number of case studies using a variety of airborne hyperspectral data are discussed covering themes such as spectral/lithological mapping, detection of alteration
minerals associated with various mineral deposits including volcanic-massive sulphides and orogenic gold, the effect of lichen and other flora on spectra as well as the effect of weathering on spectra. |
