Short summary
A major mountain building event, called the Lufilian orogeny, deformed the rocks that host copper and cobalt ore in the world-class Central African Copperbelt. Key field evidence in this study shows that a single pulse of deformation caused a set of complexly interacting folds and faults. The specific composition and layering in the rock package has a major influence on how the rock sequence was folded.
