Calibrating a Handheld LIBS for Li Exploration in the Barroso–Alvão Aplite-Pegmatite Field, Northern Portugal: Textural Precautions and Procedures When Analyzing Spodumene and Petalite
Dias, Filipa; Ribeiro, Ricardo; Gonçalves, Filipe; Lima, Alexandre; Roda Robles, María Encarnación ; Martins, Tânia (MDPI, 2023-03-26)In pegmatites containing abundant petalite and spodumene, such as those from the Barroso–Alvão (BA) aplite-pegmatite field, calibrating a portable laser-induced breakdown spectroscopy (pLIBS) equipment to identify and ... -
Interpretation of the Reflectance Spectra of Lithium (Li) Minerals and Pegmatites: A Case Study for Mineralogical and Lithological Identification in the Fregeneda-Almendra Area
Cardoso Fernandes, Joana; Silva, João; Perrotta, Mônica M.; Lima, Alexandre; Teodoro, Ana Claudia; Ribeiro, Maria Anjos; Dias, Filipa; Barrès, Odile; Cauzid, Jean; Roda Robles, María Encarnación (MDPI, 2021-09-15)Reflectance spectroscopy has been used to identify several deposit types. However, applications concerning lithium (Li)-pegmatites are still scarce. Reflectance spectroscopic studies complemented by microscopic and geochemical ... -
Tools for Remote Exploration: A Lithium (Li) Dedicated Spectral Library of the Fregeneda–Almendra Aplite–Pegmatite Field
Cardoso Fernandes, Joana; Silva, João; Dias, Filipa; Lima, Alexandre; Teodoro, Ana Claudia; Barrès, Odile; Cauzid, Jean; Perrotta, Mônica; Roda Robles, María Encarnación ; Ribeiro, Maria Anjos (MDPI, 2021-03-16)The existence of diagnostic features in the visible and infrared regions makes it possible to use reflectance spectra not only to identify mineral assemblages but also for calibration and classification of satellite images, ...
