Ore deposits are sources of raw materials for industries. This paper examines the types of ore deposits in Nigeria. Ores of iron, tin-niobium-tantalum deposits, and precious metals in the Nigerian basement complex are predominantly associated with the metasediments (gneisses and schists). Associated with the older granites and metavolcanics are ores of nickel, chromium. …
