Description

This image displays a polished slice of an iron meteorite, revealing a prominent and intricate Widmanstätten pattern of intergrown kamacite and taenite crystals. The surface is predominantly silvery-grey with areas of yellowish-brown, likely due to etching and minor oxidation.

Geological Context

Iron meteorites are remnants of the cores of differentiated asteroids that formed early in the solar system. They represent the metallic material that separated from silicate rock during the cooling and crystallization of these planetary bodies, subsequently fragmented and fell to Earth.
