Spectacular slice of Muonionalusta meteorite; Metallic meteorite IVA. Fine octahedrite. Cut and polished section to reveal the Widmanstätten structures. Comes with box and description.
Weighs approximately 18.9 grams and measures approximately 5 x 3.7 cm.
*Widmanstätten structures are present in certain metallic meteorites and lithosiderites. They result from the intergrowth of taenite and kamacite bands (two iron [Fe] and nickel [Ni] alloys), produced by very slow cooling over a prolonged period, on the order of 100 to 10,000 °C/Ma. This explains why this structure cannot be reproduced in the laboratory.
