Yellowknife greenstone belt
geological region of the Northwest Territories, Canada
The Yellowknife greenstone belt, also called the Yellowknife volcanic belt, is an Archean greenstone belt in the southern Slave craton, Northwest Territories, Canada. It is mostly made of mafic volcanic rocks (basalt and andesite) and is bordered to the east by batholithic intrusions of the Western Granodiorite Complex and beyond to the north by the Duckfish Lake Granite. Most of the Yellowknife townsite and the Con and Giant gold mines are within the Kam Group. The Yellowknife greenstone belt stands out as a positive topographic feature.
The Yellowknife greenstone belt is composed of metavolcanic rocks of the more than 2.70 billion-year-old Kam Group (consisting of the Chan, Crestaurum, Townsite and Yellowknife Bay formations) and the 2.69 to 2.66 billion-year-old Banting Group (including the Ingraham, Walsh and Prosperous formations). It is crosscut extensively by syn to post-volcanic gabbro dikes and sills and quartz-feldspar porphyry dikes. Gold deposits occur in quartz-carbonate-bearing shear zones within the mafic rocks, and quartz lodes within greywacke-mudstone turbidites.
The public source identifies “Yellowknife greenstone belt” as geological region of the Northwest Territories, Canada. This brief keeps that definition visible, then builds a research path around Yellowknife, greenstone and belt.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Yellowknife greenstone belt”, the useful work is to connect “geological region of the Northwest Territories, Canada” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 25, 2026. The linked authority identifier is Q8051959. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
