Pallasite - Wikipedia
The pallasites are a class of stony–iron meteorite. They are relatively rare, and can be distinguished by the presence of large olivine crystal inclusions in the ferro-nickel matrix.
Stony-Iron Meteorites: Their Origin, Classification, Pictures - Geology.com
Pallasites and mesosiderites may be the odd couple of the meteorite world, but their unusual makeup provides us with some valuable clues about the early days of our Solar System, and gives us a glimpse into the processes at work inside ancient asteroids.

Pallasites – Buseck Center for Meteorite Studies
Pallasites are believed to form between the silicate mantle, or outer shell, and molten metal core of a differentiated asteroid. The primary silicate mineral in pallasites is olivine, distinguishable by its greenish hue.

The main pallasite contains several regions of “massive” olivine clusters up to 11 cm in diameter with thin metal veins only a few millimeters in width. Fo86.4 with molar Fe/Mg = 0.1367, Fe/Mn = 40.37, and Ni = 0.03 wt%. Zoning was not observed for Al, Cr, Ca, Mn, or Fe typical of olivines in main-group pallasites.
The Sericho Pallasite Meteorite - Geology Science
2024年7月1日 · The Sericho Pallasite Meteorite is a rare and fascinating type of meteorite that belongs to the group known as pallasites. Pallasites are a type of stony-iron meteorite characterized by a unique and striking composition, consisting of olivine crystals embedded in an iron-nickel matrix.
Pallasite | meteorite | Britannica
As a meteoroid travels through the atmosphere, friction heats it up, creating a glowing trail of hot ionized gases (plasma) called a meteor. If the object survives both its passage through the atmosphere and its subsequent impact on the ground, it is called a meteorite. Over 99 percent of meteorites are fragments of asteroids.
