Abstract

In the area of the Krivoy Rog-Kremenchug suture zone, the optical characteristics of landscape elements were studied, both at iron ore deposits and above predicted morphostructures on iron ore deposits. Within the predicted morphostructures with a high magnetic field (iron ore rocks of the Krivoy Rog series), measurements were made of the spectral brightness coefficient (CMF) of vegetation cover. The Landsat-8 satellite image was used to perform spectrometry analysis using factor analysis (factor analysis 2 was most indicative) and elevated values of the optical characteristics of vegetation within the morphostructures above ferruginous rocks were revealed. This made it possible to predict deposits of iron ores within the predicted morphostructures with a high magnetic field intensity.
