Meteorite Pattern - Web the widmanstätten pattern in low p iron meteorites forms either at a temperature below the (α + γ)/(α + γ + ph) boundary or by the decomposition of martensite below the martensite start temperature. Perhaps the most prominent of these are chondrules. Though features of orientation can be. This is formed by the extremely slow cooling rate of the meteorite, which decreases by about 1°c per million years, forming solid diffusion after tens of millions or even. Three basic structural components may be visible on broken surfaces. Web the spiderweb pattern within the fusion crust is made up of contraction cracks, caused by rapid cooling in cold air at high altitude once the stone stopped burning in the atmosphere. The pattern is named for alois von widmanstätten, a viennese scientist who discovered it in 1808. Thomson was attempting to remove oxidized material from a specimen of the krasnojarsk pallasite. It is thought that the william thomson actually discovered these patterns earlier and published his findings in 1804,. 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.

With this information, one can estimate the size of the meteorite's parent body, because larger asteroids cool more slowly than small. 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. The reaction γ → α + γ, which is normally assumed to control the formation of the widmanstätten pattern, is not applicable to the metal.
