Liberia has some of the largest iron ore reserves in Africa, with iron content of 30% to 67%, in banded iron formations from the Precambrian. The high grade ores, with more than 60% are primarily hematite, while lower grade ores with 30 to 40% iron are generally magnetite. Liberia also has medium-grade deposits of mixed hematite and magnetite.

The three major, widely accepted tectonothermal events for the WAC; the 3.5 to 2.9 Ga Pre-Leonean and Leonean Orogeny, the 2.9 to 2.8 Ga Liberian Orogeny, and the 2.15-1.8 Ga Eburnean Orogeny. [6] A definitive answer has strong implications on the geodynamic processes controlling the craton stabilization and maturation after the Archean ...
