Abstract: The lateritic nickel deposit in the northern Great Dyke of Zimbabwe is strictly controlled by the outcrop of peridotite and landform. The orebodies occur in the foreland valley and gentle slope. The peridotite, pyroxenite-peridotite belt and chromite layer form alternating rhythmic sequence on the top of the Great Dyke. The vegetation in the peridotite cropped area is mostly sparse herb plants; while that in the pyroxenite-peridotite belt is dense trees.
