Lower Cretaceous alkaline-carbonatite complex (10 km diameter) in Precambrian granito-gneissic basement.

Carbonatite ring, rimmed to the east by fenitized ijolites, within nepheline syenite body.

Younger alkali gabbro/syenite intrusion.

Abundant fluorite occurs in places in the carbonatites (Lapido-Loureiro 1968), and pyrochlore is plentiful in residual deposits.

Geochronology

Mineralization age: Early/Lower Cretaceous : 138 Ma to 126 ± 4 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
