Souzalite occurs as a rare hydrothermal alteration product of
scorzalite in complex zoned
in sedimentary phosphate nodules, and in high-pressure kyanite deposits.
Souzalite is associated with scorzalite
At the type locality, the Córrego Frio mine, Linópolis, Divino das Laranjeiras, Minas Gerais, Brazil, souzalite is a hydrothermal alteration product of, and more abundant than, scorzalite in the pegmatite. The mineral assemblage includes albite, muscovite, quartz, apatite, zircon and tapiolite (AM 33.205).
At Rapid Creek, Dawson mining district, Richardson Mountains, Canada, souzalite occurs with gormanite (Dana).
