Term applied to elongate or beltlike areas within Precambrian shields that are characterized by abundant greenstone [meta]. An individual belt may contain the deformed and metamorphosed rocks of one or more volcano-sedimentary piles, in each of which there is typically a trend from mafic to felsic volcanics. The resultant volcano-sedimentary complexes are of economic interest as host rocks for presumably volcanogenic metal deposits.

Geological keywords, such as “granite”, “lake”. The definitions are generally taken from the AGI Glossary of Geology. Keywords with a geographic context (e.g. Cape Smith Fold Belt, Selwyn Basin, Grenville Province) are assigned to a separate category.
