The Location and Structure of the Precambrian Kisseynew Gneiss Domain of Northern Saskatchewan
The Kisseynew Gneisses occupy a large structural basin which can be traced from Reindeer Lake to Kisseynew Lake in Saskatchewan, and for at least 70 mi (113 km) east of the provincial boundary with Manitoba. The domain is flanked on the south and west sides by metavolcanics and metasediments of the...

The Kisseynew Gneisses occupy a large structural basin which can be traced from Reindeer Lake to Kisseynew Lake in Saskatchewan, and for at least 70 mi (113 km) east of the provincial boundary with Manitoba. The domain is flanked on the south and west sides by metavolcanics and metasediments of the Amisk Series, and by their presumed equivalents of a higher metamorphic grade. The northern boundary is composed of foliated granodiorites.The rocks have been assigned to two lithological groups, the Nokomis and the Sherridon, which correspond to similar divisions of the Kisseynew gneisses in Manitoba. The Nokomis is predominantly a graphite bearing pelitic gneiss containing cordierite and sillimanite, with subsidiary amphibole bearing gneisses and calc-silicates. It is characterized by a low aeromagnetic relief (< 61 300 γ).
