Troubles With Tubules: How Do Iron-Mineral Chemical Gardens Differ From Iron-Mineralized Sheaths of Iron Oxidizing Bacteria? [PDF]

Although typically lacking carbonaceous matter, many are reasonably interpreted as the remains of filamentous microorganisms coated with crystalline iron oxyhydroxides. Iron‐oxidizing bacteria (IOB) acquire such a coating naturally during life.
