A LCT pegmatite spectral library of the aldeia spodumene deposit: contributes to mineral exploration. In 2023 IEEE International Geoscience and Remote Sensing Symposium (IGARSS). p. 3704-3707. ISBN 979-8-3503-2010-7979-8-3503-2010-7http://hdl.handle.net/10198/29402Several methodologies can be employed in the prospection of Lithium (Li) in hard-rock (pegmatites). Spectrometry analysis, a Remote Sensing (RS) technique, can be applied to understand the surface spectral response of a sample, both to identify the rock-forming or alteration minerals in its composition and to validate the data collected in situ (by sensors onboard satellites/drones, for example). This paper aims to make available for public use the information acquired on the spectral composition of rock samples from the Barroso pegmatite field in Portugal, within the scope of the INOVMINERAL4.0 project. As a result, a spectral library was created with 47 spectra, collected from 11 different samples. All data is made available in a universal format, thus contributing to open science, corroborating the validation of local spectral data, and stimulating the creation of other databases, in other locations.engReflectance spectroscopyLCT pegmatiteSpodumeneLithiumMineral Explorationconference paper10.1109/IGARSS52108.2023.10281698
