Remote sensing imaging spectroscopy can also be used in regional exploration (Hook, 1990) because iron ore minerals and their alteration products have distinct spectral signatures (Clark and others, 1993). The magnetic character of iron-formation is dependent on magnetic mineral content, alteration, structural attitude, and remanent magnetization.
