Review:
Stony Iron Meteorites (pallasites)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Pallasites are a rare and striking type of stony-iron meteorite composed of a mixture of silicate minerals (mainly olivine and pyroxene) embedded within an iron-nickel metal matrix. They are believed to originate from the boundary region between the metallic core and silicate mantle of differentiated planetesimals that were shattered during collisions in the early solar system. Their unique composition results in visually stunning specimens, often displaying vibrant olivine crystals contrasted against metallic backgrounds, making them highly prized by collectors and scientists alike.
