Sn-Nb-Ta-T-(Y, REE, Li) deposit associated with the A-type Madeira granite.

Note on the mineral list: Bastos Nero et al. (2009) also mention "waimirite" and "atroarite".

Xenotime-(Y) from the deposit is highly enriched in fluorine, with up to 5.10 wt.% F for the material from core albite-enriched granite.

These pegmatites fit in the CMS (Dill, 2016) classification as the 24dE type because they are hosted in peralkaline igneous rocks and are carriers of REE-Y ores. According to the classification by Černý and Ercit (2005), they belong to the Rare Elements class and the NYF family, as they are rich in REE, Nb, Y and F, and are associated with A-type granites in environments with low pressures and temperatures.
