Online_Linkage: Description: Abstract: Wijinnedi Lake map area The Wijinnedi Lake area, a 1:50 000 scale map sheet in the southwestern Archean Slave Province, is divided into four lithotectonic domains. The three western domains are separated by Archean ductile shear zones. In the northwest, the structurally highest Wijinnedi domain consists of a 2670 Ma Yellowknife Supergroup felsic volcanic centre in part mantled by more mafic volcanic rocks that are overlain by tightly to isoclinally folded pelite dominated siltstone-fine greywacke turbidite sequence. The lower pressure facies series metamorphic grade ranges from lower greenschist to middle amphibolite but reaches migmatite grade locally at the east end of the domain. To the south the Hinscliffe domain consists mainly of a poly-phase, in large part recrystallized, ca. 2.65 Ga trondhjemite complex complexly intruded by mafic amphibolite synplutonic dykes. To the southeast, the Ghost domain, representing midcrustal structural levels is dominated by plutonic bodies with the areally most extensive tonalite and related tonalite gneiss intruded about 2.64 to 2.63 Ga while a group of mainly granite intrusions were emplaced at about 2.60 Ga. The less abundant Yellowknife Supergroup pelitic metasedimentary rocks and intermediate volcanic rocks are represented by migmatites. Most of the domain is at granulite grade with most of the plutonic bodies crystallizing under granulite grade conditions. The Dauphinee domain in the eastern part of the area, separated from the high grade rocks to the west by a Paleoproterozoic cataclastic shear zone, consists mainly of quartz dioritic to granitic rocks and minor metasedimentary migmatites that are not at granulite grade.
