Abstract
The paper presents main results of processing and analysis of hyperspectral data during forecasting and exploration in the Lomamsky potential gold ore field (The Republic of Sakha, Yakutia) for identifying hydrothermal-metasomatic rock alteration zones favorable for gold ore localization. The application of the developed technology allows identifying mineral localization areas at the preliminary stage of exploration. Comparison of the results of processing and analysis of space hyperspectral data and terrestrial geochemical surveys shows that spectrometric halos of hydrothermal-metasomatic alterations coincide in most of the areas with elevated and high content of elements of gold and silver primary geochemical dispersion halos. Complex spectroscopic haloes of the hydrothermal-metasomatic alterations of wallrock accompanying precious metal mineralization for promising Bilibinsky and Ekhundinsky areas, were detected.
