Mafraito: http://www.mindat.org/photo-367241.html

- Mafraíto: rocha granular (plutonito) grosseira, afim dos gabros e dos teralitos, com fenocristais de anfíbolas (kaersutite e barkevicite), de titanaugite violácea e de labradorite. Contém, ainda, em menores percentagens, biotite, horneblenda verde fibrosa, esfena e magnetite. Descrita por Lacroix, em 1920.
... o nome evoca, erradamente, Mafra. Esta rocha é, sim, proveniente do rio Touro, na serra de Sintra, tendo a confusão resultado da troca das amostras enviadas por Paul Choffat a Lacroix.
Ref.: Sopa de Pedra, Prof. Galopim de Carvalho

- Mafraíto is a rock whose name wrongly evokes Mafra, a village in the Lisbon district. This rock is more exactly from the Touro River, in the Sintra mountain, and the confusion results from the exchange of specimens between Paul Choffat and Alfred Lacroix.
The mafraíto is a gross granular rock (plutonite) in the family of the gabbros and 'teralitos', with phenocrystals of amphibole (kaersutite and barkevicite), violet-titanaugite and labradorite. It also contains in smaller percentages, biotite, fibrous green hornblende, 'esfena' and magnetite. Described by Lacroix in 1920.
