Located about 7 km SW of Pires do Rio.
Thrust-sense shear zone.
2-4 X 50 meter quartz-calcite-gold vein located at the internal rim of a granite body (endocontact), with mylonitic foliation of the host rock.
The biotite-garnet granite, intrusive in granulite of the Anapolis-Itaucii complex, is hydrothermally altered and deformed.
At the contact, the garnet of the mylonitic granite is replaced by chlorite.
