Geochemistry and petrogenesis of the Mesoarchean granites from the Canaã dos Carajás area, Carajás Province, Brazil: Implications for the origin of Archean granites
Autor: Roberto Dall'Agnol, Gilmara Regina Lima Feio
Publikováno v: Lithos. 154:33-52
Four Mesoarchean (2.93 to 2.83 Ga) granite units, which encompass the Canaa dos Carajas, Bom Jesus, Cruzadao and Serra Dourada granites, were recognized in the Canaa dos Carajas area of the Archean Carajas Province. The Mesoarchean units are composed
