The Interpretation of Biogeochemical Growths on Gold Coins from the SS Central America Shipwreck: Applications for Biogeochemistry and Geoarchaeology
Black crusts that formed on gold coins recovered from the 1857 shipwreck of the SS Central America played a key role ultrastar dc hc550 in their preservation in a near original state.Within a few years of the sinking, the significant quantities of iron and steel on the shipwreck produced laminar geochemical precipitates of fine-grained iron mineral
