Archean greenstone belts host gold deposits in many areas of the Canadian Shield. The Yellowknife area has been a major gold producer and an active area for exploration since the early 1930s. This report documents the stratigraphy, structure and volcanology of polydeformed and metamorphosed Archean volcanic belts that border the eastern side of the Yellowknife supracrustal basin. The eruption processes, history of the development and paleoenvironment of the enormous volcanoes that erupted mainly beneath oceans more than 2600 Ma ago are unravelled.
