We have seen that deposits of Fe and Mn are vast, with reserves in single deposits as high as 10. tons of metal. For U, the largest deposits have 2 × 10. tons; the largest U.S. deposit (at Grants, New Mexico) has only 45,000 tons of U.O. (Cheney 1981, table 4).

For North American geologists, there has been a tendency, now fading, to regard economic geology as synonymous with the study of hydrothermal deposits. At one ti

Virtually all of the world’s Al and perhaps one third of its Ni comes from such deposits (Lelong and others 1976, p. 147). Aluminum ores overlie a variety of rock types, but Ni is associated exclusively with ultramafics, reflecting the relative abundance of the

Also, note another large group of deposits in the Proterozoic, that occur at the same time as the largest iron ore accumulation. Geochemically, manganese behavior is controlled by the ox
