Physical properties

Formation & geological history

Formed at the core-mantle boundary of a differentiated asteroid about 4.5 billion years ago. The metal and silicate segments solidified together under high pressure before the parent body was shattered by a collision.

Uses & applications

Scientific research, museum display, high-end jewelry, and private collecting. Pallasites are considered the most beautiful meteorites.

Geological facts

Pallasites are incredibly rare, representing less than 1% of all known meteorites. They contain gem-quality olivine crystals, known as peridot when found on Earth.

Field identification & locations

Identify by the presence of translucent green/yellow crystals embedded in a solid iron-nickel matrix. Often found in known fall zones (strewn fields). Authenticity is confirmed via X-ray fluorescence (XRF) or acid etching to show the Widmanst$дtten pattern in the metal.
