The Serra da Acauã Stock is inserted in the context of Ediacaran plutonic activity, one of the most important geological features of the Borborema Province, NE of Brazil. The body is divided into two facies: one fine to medium equigranular and other medium to weakly porphyritic unequigranular with K-feldspar phenocrysts. U-Pb determinations in zircon indicated an ediacaran age of c. 578 Ma for its crystallization. Petrographically, the stock consists of hololeucocratic to leucocratic biotite-monzogranites (M = 1.3% – 9.9%), with biotite being the main mafic (0.5 to 8.1%). Opaque minerals, titanite, allanite, apatite and zircon are accessories and the earliest mineral phases. Geochemically, the rocks that form the st...
