Special Info

Type Locality

This is a meteorite which fell in 1516 and not found until 1958. It is sawed on one side, so probably analyzed. You can actually see some alterations to a green mineral, indicating there is a component of nickel in the mineral. The Akaganeite is within the orange crusts at the top and sides and mixed with goethite.
