2 天前  Concretions and nodules, which may also be composed in part of the iron oxy-hydroxides, limonite and goethite, come in a wide variety of shapes. Sometimes they’re shiny on the surface, which might give the impression of a meteorite fusion crust. Note that while pure hematite is rich in iron, it does not attract a simple magnet. Magnetite, on the other hand, is highly attracted to magnet, and it often
