Geological Occurrences and Relevance of Iron Oxides
The environmental dependence of iron oxide formation, itself, enhances the relevance of studying iron oxides as indicators of present and past conditions (e.g., temperature, moisture, pH, and redox state). In this brief chapter we give a succinct and selective view of some key aspects of iron oxide mineral formation and transformations Therefore, recent discoveries of widespread and abundant greenalite nanoinclusions in well-preserved 2.4 to 3.5 billion-year-old South African and Australian BIF cherts suggest that iron silicatesWidespread Deposition of Greenalite to Form Banded Iron

Application of Iron Oxide Nanomaterials for the Removal of
From the sixteen phases of iron oxides/hydroxides amorphous hydrous ferric oxide, goethite (α-FeOOH), hematite (α-Fe 2 O 3), maghemite (γ-Fe 2 O 3), magnetite (Fe 3 O 4), and ferrihydrite (Fe 5 HO 8 •4H 2 O), are the most widely used iron-based nanoadsorbents for heavy metals. This is because of their higher adsorption affinity and The broad perspective of iron oxide nanoparticles (IONPs) in nanomedicine is continuously progressing as researchers in the fields of nanotechnology, biotechnology, medicine, and engineering seek to solve present challenges and also modify existing methodologies.

The effect of [Fe3+]/ [Fe2+] molar ratio and iron salts
Phase structure and surface property. Figure 1 represents the XRD patterns of iron oxide nanocrystals prepared with different molar ratios of [Fe 3+]/[Fe 2+].Because of the surface coating and small crystalline size, the lower intensity and the broader peaks than bulk materials could be observed (Woo et al. 2004).The average Iron and some alloys of iron are also magnetic. Iron is about eight times heavier than water (its relative density is 7.87). When iron is exposed to air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds.Iron Geoscience Australia
