But isn't majorite itself a solid solution? I don't see a name for the specific species that has no aluminum in it.

@g.z. Minerals in general are solid solutions. Endmember chemucally pure minerals are extremely rare in nature. A mineral gets its own name when it’s dominated by a certain component (majorite in this case). This is as close as it gets.

@g.z. Just like you never see “forsterite” in nature. But if an olivine is sufficiently magnesian, we will call it forsterite even if there’s a bit of Fe and Ni in it.
