Abstract(s)
Several 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.
