Achondrite Meteorites for Sale

There are two types of stony meteorites, CHONDRITES and ACHONDRITES. On this page you will find Achondrites.

Definitions

  • Chondrite (n) A type of meteorite containing mineral spheres called chondrules.
  • Chondrule (n) Millimeter-sized mineral spheres found in stony chondrite meteorites. Chondrules are formed by re-melting of mineral grains in the solar nebula.
  • Achondrite (n) A class of meteorites that lack chondrules. Achondrites are formed by igneous processes on or near the surface of larger asteroids or planets. Many achondrites resemble igneous rocks on Earth, especially basalt. Meteorites that originate on Mars or the Moon are achondrites.

    ASTEROIDAL ACHONDRITES

    These are achondrites that originate in the asteroid belt as opposed to on the moon or Mars.

    HED Group Achondrites

    The best-known asteroidal achondrites form the HED group. HED stands for Howardite, Eucrite, Diogenite. These rocks have a similar isotope chemistry. Scientists believe that they originate on the asteroid 4 Vesta.

    Where do Achondrites come from? How are they formed?

    Like chondrites and irons, scientists believe that most achondrites originate in the Asteroid Belt between Jupiter and Mars. A few achondrites are thought to originate on the Moon or Mars.

    The classification of ACHONDRITES is seemingly more complex than irons or chondrites. Most achondrites are the result of igneous processes—the processes of melting and recrystallizing of rocks. At the beginning of the igneous process, the rocks that were melted were probably chondrites. Sometimes the melting was partial. Some parts of a rock melted and flowed away from the rest. The liquid then hardened into a rock of a different composition. The material that was left behind formed a rock of still another composition. Both would be described as differentiated rocks. These two rocks would be two kinds of achondrites. A third kind of achondrite would be a rock (like a chondrite) that was simply melted and cooled. The original chondritic texture would be completely replaced by igneous texture.

    (When thinking of igneous rocks, it is important to realize that the cooling was very slow. These rocks have a crystalline texture like igneous earth rocks such as granite or basalt. They do not look like slag or glass.)

    Scientists further group and divide achondrites on the basis of oxygen isotopes and other geochemical indicators. For more information about how this is done, see the books Field Guide to Meteors and Meteorites, Rocks from Space and Meteorites and Their Parent Planets. Our Type Table has some information too.
