This meteorite will possibly receive an official name of '***' - to be confirmed by the Nomenclature Committee of the Meteoritical Society.

The type specimen (**g) will be on deposit at the University of Plymouth, along with a single, polished block.


Types of Ordinary Chondrite

Not only can ordinary chondrites be defined by their metal content, but they can also be assigned a 'petrologic type' based on textural and compositional features across the meteorite. For ordinary chondrites, this scale ranges from type 3 to type 7. The higher the petrologic type the more altered the meteorite, and this can be seen through a number of features.

One key feature to look out for when defining a petrologic type for ordinary chondrites is the state of the chondrules. Type 3 ordinary chondrites have an abundance of pristine chondrules that are very round and well defined, but as alteration progresses to type 7, chondrule boundaries become blurred and difficult to identify.

MGUK 02 had few obvious chondrules, with lots displaying blurred boundaries that were hard to make out against the rest of the sample. As a result, the sample was assigned petrologic type 6.
