Meteorite Pattern

Meteorite Pattern - In the early 1800s, a british geologist remembered only as g or possibly william thomson discovered a remarkable pattern while treating a meteorite with a solution of nitric acid. The reaction γ → α + γ, which is normally assumed to control the formation of the widmanstätten pattern, is not applicable to the metal. The interlocking crystals of the two minerals combine to form a characteristic arrangement, the widmanstätten pattern, which indicates the relatively low pressure at which iron meteorites are formed. Though features of orientation can be. These patterns were named after the austrian count alois von beckh widmanstätten who discovered these patterns in 1808. If an iron meteorite is sawn, polished, and etched with an appropriate acid solution, the individual metal grains are revealed in a geometric array called a widmanstätten pattern.
