Caption

Widmannstatten structures are a distinctive pattern of intertwined crystals in iron-nickel meteorites, made visible by chemical etching of a polished surface. They result from crystal growth, during slow cooling, in larger chunks of iron-nickel meteorites, and consist of intertwined crystals of two different alloys of nickel-iron, kamacite and taenite. They are named after the first scientist to describe them, Aloys von Widmannstatten, director of the Technical Museum of Vienna in the early 19th Century. Actual width of sample is 60 mm.
