| This means there are a lot of different groups and sub-types of iron meteorite and they can be related to both stony achondritic and chondrite meteorites. |
| While still on the parent body, much of the achondritic material was formed by igneous processes similar to those occurring on Earth today. |
| We have a major research program to investigate the thermal histories of lunar rocks, achondritic meteorites, and Martian meteorites. |
| Stony-irons would then be samples from the boundary between the achondritic upper layers and the core. |
