Silica and iron mobilization, cave development and landscape evolution in iron formations in Brazil
Iron formations display some of the oldest and most enigmatic landforms on Earth, presently
restricted to few areas of the planet. The original rock, the Banded Iron Formation (BIF) was …

Enhanced terrestrial Fe (II) mobilization identified through a novel mechanism of microbially driven cave formation in Fe (III)-rich rocks
Most cave formation requires mass separation from a host rock in a process that operates
outward from permeable pathways to create the cave void. Given the poor solubility of Fe (III) …
