The Sapucaia mine is approximately 60 km due east of Governador Valadares, and 16 km ENE of Galiléia. It lies within the Conselheiro Pena Pegmatite District of the Eastern Brazilian Pegmatite Province. Mining began in the early part of the 20th century, but the time of greatest activity was during the Second World War when the mine produced industrial beryl and muscovite. It still produces feldspar and rare minerals for collectors.
The Sapucaia Pegmatite intrudes garnet-staurolite-muscovite-biotite schists of the São Tomé Formation (Rio Doce Group) and sericite quartzites of the Crenaque Group, all of Neoproterozoic age. The pegmatite forms a lenticular body elongated in a NW-SE direction and dips at about 70 degrees to the NE. Weathering processes and the introduction of metasomatic fluids led to the formation of many secondary phosphates. The pegmatite is lithium-rich and is the type locality for eight minerals, all of them phosphates. Among collectors, the mine is best-known for the phosphates (especially iron-rich ones) and rose quartz. It is NOT known for any tourmaline group mineral or any variety of beryl or spodumene.

541 - 1000 Ma
|Neoproterozoic plutonic rocks|
Age: Neoproterozoic (541 - 1000 Ma)
Comments: Deep-seated to high-level intrusions are included. Many charnockites, anorthosites, and large ophiolites, classified as plutons, are distinguished in the database using the SIGNIF item. Ophiolites were classified as plutons, even where remnants may be extrusive and/or sedimentary.
Lithology: Plutonic rocks
