Throughout the Phanerozoic Era, magnetite‐series and ilmenite‐series granitoids are heterogeneously distributed on both sides of the Pacific Ocean. Ilmenite‐series granitoids are dominant in the western Pacific rim, while magnetite‐series granitoids prediminate in the eastern Pacific orogenic belt. Regional distribution patterns of the two series of paired belt are also recognized differently, implying different tectonic and geochemical settings on both sides of the Pacific Ocean. The differences reflect on the predominance of Sn‐W deposits in the western Pacific but sulfide‐forming mineral commodities in the eastern Pacific rims. To determine redox state of granitoids is the first step in mineral exploration of granitoid affinity.
