Schematic geological map of Abitibi greenstone belt and surrounding geological features. (Locations of seismic reflection lines are identified by numbers.)

This slide shows the extent of the Abitibi greenstone belt, the most prominent of its type in the Superior Province. It is bounded on the southeast by the Grenville Front we looked at just a minute ago. Another fault borders the belt on the west and northwest, separating it from the Kapuskasing Structural Zone (KSZ). Within the greenstone belt occur several types of rock formations as indicated in the legend. The named townsites are well-known mining communities, and the Abitibi greenstone belt contains many important precious and base metal mines.
