Reflectance spectroradiometry applied to a semi-quantitative analysis of the N4ws deposit, Carajás Mineral Province, Pará, Brazil
Reflectance spectroradiometry is a well-known and effective technique for identifying the mineralogy of mineral deposits in the different stages of mineral exploration, from prospection to production (Herrmann et al., 2001, Ducart et al., 2006, Harraden et al., 2013 and Dalm et al., 2014).

| Resumo: | Reflectance spectroradiometry is a well-known and effective technique for identifying the mineralogy of mineral deposits in the different stages of mineral exploration, from prospection to production (Herrmann et al., 2001, Ducart et al., 2006, Harraden et al., 2013 and Dalm et al., 2014). Spectral analyses of these deposits allows for a better understanding of mineralised areas that can provide additional information on the spatial distribution of minerals, assisting the identification of ore zones and associated contaminants. Analysis of absorption bands due to electronic transitions, vibrational modes, charge transfer, and other processes (e.g., see Hunt, 1977) is used for the mineral identification. |
