Spectral Library of European Pegmatites, Pegmatite Minerals and Pegmatite Host-Rocks – the GREENPEG project database

Abstract. The New Exploration Tools for European Pegmatite Green-Tech Resources (GREENPEG) spectral database contains the signature, obtained through reflectance spectroscopy studies, of pegmatites and minerals as well their host rocks. Samples include Nb–Y–F (NYF) Li–Cs–Ta (LCT) chemical types rocks from pegmatite locations in Austria, Ireland, Norway, Portugal, Spain. spectra (raw continuum-removed spectra), sample photographs, main absorption features automatically extracted by a self-proposed Python routine. Whenever possible, mineralogy was interpreted based on spectra. A detailed description database, its content structure, measuring instrument, interoperability with geographic information system (GIS) tools is available this report. Moreover, examples how data can be used are also provided. advantages added value presented dataset reside scale, representative samples distinct genesis, mineralogy, that reference exploration at global scale via, example, satellite image processing. reported mineral assemblages interest when considering resource estimation or ore Thus, it expected open dataset, Zenodo platform https://doi.org/10.5281/zenodo.6518318 (Cardoso-Fernandes et al., 2022b), will users, ranging academia to industry.
