The photochemistry of manganese and the origin of Banded

The photochemical oxidation of Fe(2+) -hydroxide complexes dissolved in anoxic Precambrian oceans has been suggested as a mechanism to explain the deposition of Banded Iron Formations (BIFs). Photochemical studies have not yet addressed the low levels of manganese in many of these deposits, which probably precipitated from solutions bearing similar concentrations of Fe2+ and Mn2+.

Manganese Ore Deposits

manganese "manganese deposits" "manganese minerals" "manganese ores" "Mn deposits" Manganese. Manganese is the ninth or tenth most abundant element in the Earth’s crust . Most of its industrial use is in steel making with a much lesser amount going into the production of batteries. It is very similar to iron in its chemical properties.

The photochemistry of manganese and the origin of banded

Jul 01, 1992· When manganese ore deposits are present in BIFs, they are unevenly distributed; lenticular manganese oxide bands are conform- ably enclosed by Fe-rich strata. The manganese ores them- selves may be banded, with layers of hausmannite, crypto- melane, braunite, and manganese carbonates alternating with Mn-poor cherts (DORR, 1945; CRERAR et al

Otjosondu Manganese Mine Wikimapia

The Otjosondu manganese ore is associated with banded iron formation consisting of hematite-quartzite and iron-rich gneisses. The entire Otjosondu area has undergone Damaran metamorphism of at least upper amphibolite grade. The original paragenesis has been altered to a silica-rich metamorphic manganese mineral assemblage. Exploration work was directed at two targets namely detrital manganese

Banded iron formation Wikipedia

Banded iron formations are almost exclusively Precambrian in age, with most deposits dating to the late Archean (2500-2800 Ma) with a secondary peak of deposition in the Orosirian period of the Paleoproterozoic (1850 Ma). Minor amounts were deposited in the early Archean and in the Neoproterozoic (750 Ma). The youngest known banded iron formation is an Early Cambrian
