| Primitive achondrites then experienced varying degrees of melting, thermal processing, and recrystallization. |
|
| They are sometimes referred to as enstatite achondrites and might somehow be related to the enstatite chondrites. |
|
| The shop offers a wide range of Lunar and Martian meteorites along with many rare achondrites and chondrites. |

| There are a number of other achondrites that do not fit into any of the preceding groups or subgroups. |
|
| Based on their texture, stone meteorites are divided into two types, the chondrites and the achondrites. |
|
