The OPX-Bearing and OPX-Absent granitoids of the Umarizal intrusive suite, a representative example of Ediacaran A-type magmatism in NE Brazil

Ediacaran magmatism represents one of the most prominent features of the Borborema Province (NE Brazil), with the Umarizal intrusive suite a classical example of an anorthosite - mangerite - charnockite - granite (AMCG) association.

Zusammenfassung:Ediacaran magmatism represents one of the most prominent features of the Borborema Province (NE Brazil), with the Umarizal intrusive suite a classical example of an anorthosite - mangerite - charnockite - granite (AMCG) association. This study presents new geochemical and petrological data, discusses its magmatic evolution, and compares the outcomes with similar rocks of Western Africa. The Umarizal suite displays mineral associations that crystallizated under high temperature (
