A table is provided to determine the angles within the widmanstätten pattern as a function of orientation of the slice, and methods are provided to solve the inverse problem, namely to determine the orientation of the slice from measurements of the widmanstätten pattern. The widmanstätten pattern is thought to form by the nucleation and growth of kamacite from taenite during slow cooling of the parent meteorite body (owen and burns 1939). Explore the beauty and rarity of meteorite jewelry and its spiritual significance. The pattern is named for alois von widmanstätten, a viennese scientist who discovered it in 1808.

Web a table is provided to determine the angles within the widmanstätten pattern as a function of orientation of the slice, and methods are provided to solve the inverse problem, namely to determine the orientation of the slice from measurements of the widmanstätten pattern. This pattern is named after one of the first people to observe it some 200 years. Web discover the fascinating story behind the widmanstätten pattern, a unique crystal structure found in muonionalusta meteorites. This pattern is known as the “widmanstätten figure” (see metallurgy, fig. This image shows the widmanstätten pattern of a polished and etched slice of the gibeon iva fine octahedrite. Web when cut surfaces of most iron meteorites are etched with 6% nitric acid. Web widmanstatten patterns are formed by interwoven bands of kamacite and taenite, which can only form over literally millions of years of very slow cooling. The light kamacite bands are bordered by darker taenite ribbons. It has been estimated that it took about 1000 years for these molten remnants of planetary core to cool by just 1 degree celsius! Web.
