    Abstract
    Beside the Scandinavian countries and Serbia, Portugal is among the European countries with the most significant lithium resources. The Li-rich occurrences in Portugal are mainly associated with aplite-pegmatite dykes and sills intruded in granitic and metasedimentary rocks of the Central Iberian and Galicia – Trás-os-Montes geotectonic zones (Carvalho & Farinha, 2004). The Gonçalo Li-pegmatites in the Guarda district (currently only used as decorative stone) have significant economic importance. Among other deposits, Gonçalo is a reference site in the focus of the EU FAME project (www.fame-project.eu) that aims to unlock the development potential of the most promising European Sn-W-Li ore types. Results of optical microscopy, QEMSCAN©, Raman and electron-probe microanalysis of the Gonçalo Li-pegmatite deposit have been employed to determine the mineralogical variability of the pegmatites with the aim to determine the deportment of lithium and potential rare-metal by-products and to guide enhanced mineral processing technologies.

    Export search results

    The export button (to the right?) will allow you to export the search results of the entered query to a CSV file. To export the items, click the "Export" button.

    There are two options to select the items you want to export to a CSV. Either you export all results from a search query, or you select a subset of items from the search results.

    To select a subset of the search results, click "Selective Export" in the Export menu.

    After making a selection, click the 'CSV' button. The amount of items that will be exported is indicated in the bubble next to 'CSV'.

    The amount of items you can export is limited, but authenticating will increase this limit.
