The data set contains mineral chemical analyses of 20 copper-bearing minerals and their corresponding hyperspectral reflectance spectra. The hyperspectral data were acquired with the HySpex system in a range of 414 – 2498 nm and are presented in a spectral library. The resulting reflectance data are scaled from 0 - 10000. Detailed information about the mineral specimen, sample area and mineral chemistry is presented in the data sheets below. The spectral library presented here is part of a larger collection of spectral libraries including samples from rare-earth minerals, rare-earth-oxides (Koerting et al., 2019a, https://doi.org/10.5880/GFZ.1.4.2019.004) and field surface samples from a copper-gold-pyrite mine in the Republic of Cyprus (Koerting et al., 2019b, https://doi.org/10.5880/GFZ.1.4.2019.005) and are fully described in Koerting et al. (2020). These libraries aim to give a spectral overview of important resources and ore mineralization.
Twenty samples from the collection of the University of Potsdam (UP) and the Federal Institute for Geosciences and Natural Resources (BGR) were hyperspectrally measured with the HySpex system and mineral-chemically analysed by using a scanning electron microscope (SEM) and electron probe microanalyzer (EPMA).
The data set contains mineral chemical analyses of 32 rare earth element (REE) -bearing minerals (REMin) and rare-earth oxides (REO) and their corresponding hyperspectral spectra. The hyperspectral data was acquired with the HySpex system in a range of 400 – 2500 nm and is presented in a spectral library. The resulting reflectance data are scaled from 0 - 10000. The two Rare Earth Element (REE) libraries consist of the spectra of 16 rare earth oxides powders (REO) and 14 REE-bearing minerals (REMin). In addition, it contains the spectra of niobium- and tantalum oxide, two elements technically not part of the REEs. The spectral library presented here is part of a bigger collection of spectral libraries including copper-bearing surface samples from Apliki copper-gold-pyrite mine (Koerting et al., 2019a, http://doi.org/10.5880/GFZ.1.4.2019.005) and copper-bearing minerals (Koellner et al., 2019, http://doi.org/10.5880/GFZ.1.4.2019.003). These libraries aim to give a spectral overview of important resources and ore mineralization.
