This research delves into the magmatic deposits of iron (Fe) and chromium (Cr) resulting from gravitational segregation in granitic systems within S. China, particularly analyzing the Emeishan plume basalt and its associated 256 Ma Fe ores from the Pan-Xi district and Baiyuan-Ebo. It explores the intricate relationships between various geological formations, including the Ma-An-Shan andesitic porphyry, the unique structures of the Kaapvaal Craton, the Bushveld Igneous Complex, and their implications in understanding chromite-bearing and platinum-bearing intrusions, especially within the context of the Great Dike.
