Abstract

Waimirite and Atroarite are associated with the core of the albite-granite from the Madeira Granite and occur in different places as thin veins. Waimirite is a yttrium fluoride that macroscopically form massive and white rounded aggregates. Atroarite is a alumino-fluoride and macroscopically form dark grey octahedral crystals. The DRX analyses confirm that they are new minerals.
