The Queen Maud block is divided into two crustal belts. The western Perry River belt is dominated by Mesoarchean to Neoarchean granitic gneisses and supracrustal rocks; it was incorporated into the Rae domain by at least 2.46 Ga. The eastern Paalliq belt is dominated by the 2.52-2.45 Ga Queen Maud granitoids and the 2.45-2.39 Ga Sherman supracrustal sequence, both of which were formed on Neoarchean crust of the Rae domain. Slave-Churchill collision and convergence occurred ca. 2.43-2.35 Ga resulting in granulite-facies metamorphism, regional scale N-S trending strike-slip shearing, and minor crustal melting in the Queen Maud block. Post-collisional magmatism occurred ca. 2.32 Ga. Between 2.3 and 2.1 Ga mafic magmatism and monazite growth occurred in the western Queen Maud block, possibly as a result of continental rifting. The 2.01-1.91 Ga Thelon Orogeny affects only the western-most Queen Maud block, where 1.93 Ga metamorphism and very weak deformation are preserved.
