    Prospecting from Orbit - NASA

    The goal of the project is to construct a series of reports outlining where the world's known metal ore deposits such as gold, copper, and iron occur and where new deposits are likely to be found. As part of this ambitious effort, geologist Larry Rowan and a team of researchers at the USGS are now developing ways to locate potentially mineralized areas from space.

    Bog iron - Wikipedia

    Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO(OH)).. Iron-bearing groundwater typically emerges as a spring.The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the .

    Deep-Earth Structures Discovered That May Signal .

    The authors believe that the metal deposits formed when thick continental rocks stretched out and sagged to form a depression, like a wad of gum pulled apart. This thinned the lithosphere and allowed seawater to flood in. Over long periods, these watery low spots got filled in with metal-bearing sediments from adjoining, higher-elevation rocks.
