Identification of mineral deposits using airborne electromagnetic spectra
نویسنده
چکیده
Broadband frequency-domain electromagnetic sensors can be used not only to detect but also to characterize and identify a particular mineral deposit based on its spectral response. The concept is similar to identifying a particular landmine based on its unique spectral response, which is known as Electromagnetic Induction Spectroscopy (EMIS). Recent advances in single-coil, broadband sensors have brought a potential application of EMIS to airborne mineral prospecting. This paper describes a method of identifying an ore deposit using the EMIS spectrum and shows examples from a helicopter-towed digital broadband EM system.

Reflectance Spectroscopy Applied to Exploration for Mineral Deposits and Geothermal Systems, and to the Remediation of Mined Lands in the Great Basin of the United States
The Great Basin of the Western United States has thin continental crust and geologic structures that have controlled the emplacement of significant precious and base metal mineralization. Many of the mineral deposits in the Great Basin were emplaced by hydrothermal processes that altered the mineralogy of their host rock assemblages and facilitated concentration of metals. In the 1960’s and 197...

Mineral physics dictate the appearance of rocks and soils across the electromagnetic spectrum. In the Visible/Near-Infrared (VNIR) and Short Wave Infrared (SWIR), many materials absorb radiation at specific wavelengths, allowing their identification by the position and character of absorption features. Electronic processes at wavelengths less ~1.0 micrometers allow (in addition to others) ident...
