Paint Pot and Iron Oxide Concretions - Video

MVAC Senior Research Associate Dr. Connie Arzigian talks about iron oxide nodules. These concretions form where there are iron concentrations in the soil. They are much denser than other rocks, are sometimes shiny, and can be magnetic. Iron nodules form naturally, but people in the past did at times use them for various purposes such as the paint pot featured here.
