Evidence for the close relationship between ore deposits and subduction zones is compelling in many places around the Pacific Basin. Distribution of the magnetite-hematite orebodies, as well as that of the often described sulfide bodies, must be explained. The iron ore bodies are considered to be formed as a result of melting of high-iron sediments at depth close to the subduction zone, to have migrated upward, and to have been deposited closer to the subduction trench than were the sulfide deposits. The wide mineralized zones of Bolivia and Peru and of the southwestern United States are difficult to relate to either present or older recognized subduction zones.
