Amphoterite

Amphoterite is an obsolete classification of chondritic meteorites that are now classified as LL (Low Iron and Low total metal content) types.

There will be a number after the LL in a meteorites classification type, e.g. LL3, LL5, LL6.

(Types range from 3 to 7) The number indicates the amount of alteration suffered by the chondrules in the meteorite.

A chondrule is a small mineral ball generally 0.1–4 millimetres (0.0039–0.1575 in) in diameter.

An LL3 type is pristine with perfectly discernible chondrules, an LL7 type has been melted or altered by pressure or other force to almost completely obliterate the round chondrules.
