1.47" Polished Admire Pallasite Meteorite (15.3 g) Slice - Kansas
This 1.47" wide (15.3 gram) sliced and polished piece of pallasite meteorite comes from the unobserved Admire meteor fall. The thin slicing of the pallasite beautifully highlights the olivine (forsterite) crystals' translucency when backlit.
The thin slicing of this meteorite makes it relatively fragile. Please be careful when removing the specimen from packaging.

Pallasite Care - Important!
Pallasites are more susceptible to rust and deterioration from atmospheric moisture than most iron meteorites. Proper care is essential and includes avoiding direct handling with bare hands, as natural skin oils can affect the metal, and keeping the specimen in a moisture-free environment. This is especially important in high-humidity regions such as Florida. All pallasite material we sell has been stabilized and coated, which will help reduce the risk of corrosion; however, ongoing care is still necessary to preserve your specimen. We recommend storing pallasites in a dry environment, ideally with a corrosion inhibitor such as an enclosed display case equipped with a dehumidifier or desiccants.
Regular inspection is also advised. Check your specimen periodically for any discoloration, particularly brown or yellow spots, which may indicate the onset of rust. If rust is detected, prompt action is required to prevent further spread. Light rust can be treated by gently rubbing the affected area with a cotton swab dipped in CLR (Calcium, Lime, and Rust remover). Repeat as needed until the discoloration is removed, then rinse the area thoroughly with alcohol—100% pure alcohol is preferred.
After treatment, the meteorite can be baked for approximately one hour at 150°F (or 200°F for iron-only meteorites) to remove any remaining moisture. Use caution when removing it from the oven, as the metal will be hot. While still warm, a light coating bath of ATF (automatic transmission fluid) or a high-quality light oil is recommended. Once cooled, wipe away any excess oil and return the specimen to its moisture-free storage environment.

About The Admire Pallasite
The first documented pieces of this meteorite were collected in 1881 by a farmer plowing his field near the city of Admire in Lyon County, Kansas. Its fall was not observed. More than a century later, meteorite hunters returned to the site and discovered more pieces. As of today, over 2 tons have been recovered.
It is classified as a PMG (main group) pallasite, of which the major mineral assemblages consist of troilite, schreibersite, olivine (forsterite), kamacite, and taenite. Its olivine crystals still display beautiful translucence when the pallasite is cut thin, but take on much more angular shapes than olivines in other pallasites.

About Pallasites
Pallasite meteorites are a class of stony-iron meteorites. They were once believed to have originated at the core-mantle boundary of asteroids that shattered through impacts, but a recent hypothesis is that they are a mixture of core and mantle minerals.
Pallasite meteorites consist of olivine (peridot) crystals surrounded by iron-nickel matrix. Upon acid etching, some pallasites display interweaving structures known as Widmanstätten patterns (or Thomson lines) in the metallic matrix. These structures are iron-nickel alloy crystals, typically kamacite and taenite, that cooled over millions of years in the vacuum of space.
Pallasites are quite rare: only about 200 are known, and only four have had observed falls. This represents less than 0.2% of all classified meteorites!
