Native silicon and iron silicides in the Dhofar 280 lunar meteorite
Petrology, 2012The Dhofar 280 lunar highland meteorite is the first one in which native silicon was identified in association with iron silicides. This association is surrounded by silicate material enriched in Si, Na, K, and S and occurs within an impact-melt matrix.

Papua and New Guinea medical journal, 1976
Chemical analysis showed that some foods cooked in a cast iron pot gained significantly in iron content. This was particularly so for rice and green vegetables, but not for the major root staples of Papua New Guinea. It therefore seems unlikely that a campaign to encourage the use of iron pots for cooking would significantly increase the iron content ...

New Magnetic Order in Buried Native Iron Oxide Layers
Physical Review Letters, 2003The properties of a magnetically ordered buried Fe oxide layer are presented. This oxide has a room-temperature magnetization exceeding that of Fe3O4 by 42% and of gamma-Fe2O3 by 89%. The oxide consists of a component (70%) with a net moment of 2.0 micro(B)/Fe ion, while the remaining spins yield no net moment.

Native Iron in the Continental Lower Crust: Petrological and Geophysical Implications
Science, 1985Lower crustal granulite xenoliths recovered from a kimberlite pipe in western Africa contain native iron (Fe 0 ) as a decomposition product of garnet and ilmenite. Magnetic measurements show that less than 0.1 percent (by volume) of iron metal is present.

Native iron in the Palaeoproterozoic Chaibasa Formation: primary or secondary?
Geological Society, London, Special Publications, 2012Abstract Native Fe in the Chaibasa Formation may be the oldest native Fe ever found. The Chaibasa Formation contains pre-1.6 Ga offshore shelf sediments from the Singhbhum Craton in India. The sediments are light green in colour, consistent with a low content of organic matter and a metamorphic grade of greenschist–lower amphibolite facies ...

Native iron: Greenland's natural blast furnaces
Geology Today, 2015We live in an oxidized world: oxygen makes up 22 percent of the atmosphere and by reacting with organic matter produces most of our energy, including the energy our bodies use to function: breathe, think, move, etc. It has not always been thus. Originally the Earth, in common with most of the Solar System, was reduced.

Evaluation of the body iron status of native Canadians.
Canadian Medical Association journal, 1979The serum ferritin concentration was measured in 1417 Indians and 310 Inuit aged 1 to 89 years. The subjects were initially selected to produce a representative sample of the entire native population, but the rate of nonresponse was high, and the results reported in this paper are representative only of the people studied.In males the median serum ...

A Chemoproteomic Approach to Monitor Native Iron–Sulfur Cluster Binding
Iron-sulfur (Fe-S) clusters are essential redox-active metallocofactors participating in electron transfer, radical chemistry, primary metabolism, and gene regulation. Successful trafficking and incorporation of Fe-S clusters into target proteins are critical to proper cellular function.Daniel W, Bak, Eranthie, Weerapana

3. Occurrence of Native Iron in Liberia, in Africa
Proceedings of the Royal Society of EdinburghDr Hayes states that there is evidence establishing the fact that pure native iron exists abundantly in the country back from the central part of the colony of Liberia. Early travellers state that the natives of Africa find iron ore so pure, that they heat and hammer it into form.
