• Akaganeite - Wikipedia

    en.wikipedia.org/wiki/Akaganeite Akaganeite, also written as the deprecated Akaganéite, is a chloride-containing iron(III) oxide-hydroxide mineral, formed by the weathering of pyrrhotite (Fe 1−x S). Akaganeite is often described as the β phase of anhydrous ferric oxyhydroxide FeOOH, but some chloride (or fluoride) ions are normally included in the structure, ...

    www.mindat.org/min-67.html The presence of akaganeite indicates high concentrations of chloride in an acidic environment (Ståhl et al. 2003). Note: The spelling akaganéite is incorrect (Burke, 2008).
  • Akaganeite - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/earth-and-planetary-sciences/akaganeite Akaganeite (β-FeOOHCl) has been found in environments with high chloride concentrations (0.1 mol l −1), low pH (3–4), and high temperature (60°C), e.g., in hot springs and volcanic deposits. Akaganeite consists of 2 × 2 channels (referring to the width of the channels in octahedral units) built by edge-sharing double chains (Figure 2f).
