Posted on April 16, 2013 by stevepiercey

Banded iron formations (BIF) and iron ore are globally important resources of iron that have very distinctive textures.  Well-preserved BIF contain iron-rich bands consisting of iron oxides (e.g., hematite, magnetite), iron silicates (e.g., stilpnomelane), and iron oxyhydroxides (e.g., greenalite), that … Continue reading →
