WebThe mineralised layer in the Great Dyke of Zimbabwe is the most similar to the Merensky Reef, but the area of the intrusion is very much smaller. The Stillwater Complex in North America is also similar to the Bushveld Complex, but the ore zone is patchily concentrated along and vertically within a thicker layer than the Merensky Reef. WebJan 1, 2016 · The ore bodies occur as deformed bands as well as elongated lenses. Massive, banded, spotted and friable textural varieties are present. The ore and associated silicates exhibit gradational contact even if they are affected by faulting and shearing. The rocks exhibit compositional as well as modal variation from south to north.
