Iron ore deposits have long been studied for evidence of effects of the evolving ocean-atmosphere system. Manganese does not, however, show as clear a pattern of secular evolution as does iron. The mass-age distribution of manganese ore deposits (Fig. 11) shows three specific episodes of enhanced manganese accumulation:

 · In 2022, Australia's manganese ore production totalled approximately Mt (Table 2; Table 3). The total tonnage of manganese ore mined is approximately twice the tonnage produced because of yields of around 50% after beneficiation. Export data for Australia's manganese products, including manganese ore, were not available.

Manganese ores comprised more than 70 mineral types and form three groups of mineral assemblages: (a) minerals formed during low grade regional metamorphism (T ≈ 200–260 °C, P = 2–3 kbar) that compose the main part of ore bodies, (b) mineral assemblages in segregatic and metasomatic veins filling late stage tectonic fractures, and (c) an assemblage of subsurface …
