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. Intrusive equivalents (gabbro and diorite) are collectively known as the Kam Group. 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.
Famous quotes containing the word belt:
“But the lightning which explodes and fashions planets, maker of planets and suns, is in him. On one side elemental order, sandstone and granite, rock-ledges, peat-bog, forest, sea and shore; and on the other part, thought, the spirit which composes and decomposes nature,—here they are, side by side, god and devil, mind and matter, king and conspirator, belt and spasm, riding peacefully together in the eye and brain of every man.”
—Ralph Waldo Emerson (1803–1882)
