Geochemistry, U-Pb geochronology, Sm-Nd and O isotopes of ca. 50 Ma long Ediacaran High-K Syn-Collisional Magmatism in the Pernambuco Alagoas Domain, Borborema Province, NE Brazil

da Silva Filho, Adejardo F.; Guimaraes, Ignez P.; Santos, Lucilene; Armstrong, Richard; Randall van Schmus, William

Description

The Pernambuco Alagoas (PEAL) domain shows the major occurrence of granitic batholiths of the Borborema Province, NE Brazil, with Archean to Neoproterozoic range of Nd TDM model ages, giving clues on the role of granites during the Brasiliano orogeny. SHRIMP U/Pb zircon geochronological data for seven granitic intrusions of the PEAL domain divide the studied granitoids into three groups: 1) early-to syncollision granitoids with crystallization ages ca. 635 Ma (Serra do CatĂș pluton), 2)...[Show more]
