A possible iron-dominated catalytic oxidation mechanism in waterlogged archaeological wood from the Mengxihe Palaeolithic site

In marine shipwrecks, wood degradation is described by the sulfur-iron model, in which pyrite forms during burial and then oxidizes to sulfuric acid after excavation. Whether this model applies to freshwater environments remains unclear. Here, we analyzed waterlogged archaeologic...
