This template can be used to provide comparative, at-a-glance information on meteorite subdivisions.

Meteorite classification is a complex, ever evolving field with inconsistent use of terminology. This template sidesteps the complexity by providing fields for both the name of the subdivision being described and the technical term from meteorite classification that best fits it.

Subdivision is an unofficial term used here to avoid the ambiguity inherent to "Group", "Type", etc. and to "Classification" in this context.

Bold fields are mandatory.

Field Description
Subdivision The meteorite classification term that applies, most likely one of Type/Class/Clan/Group/Subgroup/Grouplet/Duo/... Note that this must be entered as a proper noun for the template to work; initial capital letter followed by lower case.

In addition to appearing at the top of the Infobox, this field places the article into Category:Meteorite <subdivision>s.

Name The official name of the meteorite subdivision without any abbreviation; likely to be in Table 1 below.
Alternative_names Comma separated alternative names.
Image Name of an example image of the subdivision without "File:" or any other wikitext (e.g. Willamette Meteorite AMNH.jpg).
Image_caption Most captions draw attention to something in the image that is not obvious, such as its relevance to the text. See Wikipedia:Manual of Style/Captions.
Image_alt_text Description of the image for visually impaired readers. See Wikipedia:Alternative text for images.
Compositional_type Set to Iron if describing a subdivision of the Iron meteorites or Stony if describing a subdivision of the Iron meteorites.
Type Choose from the first column of Table 1 below.
Class Choose from the middle column of Table 1 below.
Clan A clan name from a referenced source.
Group Likely to be in the last column of Table 1 below.

  • [[Fine octahedrite]]
  • [[Finest octahedrite]]
  • [[Plessitic octahedrite]]
  • [[Ataxite]].
Parent_body Best referenced guess or subdivision name (by convention).
Composition Chemical (irons) or mineral (stony) composition (e.g. 93% Fe, 5.9% Ni, 0.42% Co, 0.46% P).
