Application of Airborne, Laboratory, and Field Hyperspectral Methods to Mineral Exploration in the Canadian Arctic: Recognition and Characterization of Volcanogenic Massive Sulfide-Associated Hydrothermal Alteration in the Izok Lake Deposit Area, Nunavut, Canada
Download2022-02-28
Laakso, K.,, Rivard, B.,, Peter, J.M., White, H.P., Maloley, M., Harris, J., Rogge, D.
We have investigated the application of ground, laboratory, and airborne optical remote sensing methods for the detection of hydrothermal alteration zones associated with the Izok Lake volcanogenic massive sulfide (VMS) deposit in Nunavut, Canada. This bimodal-felsic Zn-Cu-Pb-Ag deposit is...

Laakso, K., Peter, J.M., Rivard, B., White, H.P.
Short-wave infrared (SWIR) field and laboratory spectra were used to identify and characterize hydrothermal alteration mineral chemical variability in host rocks proximal to the Izok Lake Zn-Cu-Pb-Ag volcanogenic massive sulfide (VMS) deposit in Nunavut, Canada. The deposit is hosted within a...

Laakso, K., Turner, D.J., Rivard, B., Sánchez-Azofeifa, A.
Rare earth elements (REEs) are a group of metals essential to high technology industries. This high demand, combined with a high supply risk, has led to an understanding that REEs are critical to society. Despite the potential that hyperspectral imaging (HSI) data offers for a fast and...
