Recommended classes in the Meteoritical Bulletin Database are assigned by the database editor. In most cases, this is based on the most recent classification that appears in either the Catalogue of Meteorites, MetBase, the US Antarctic Meteorite Newsletter, the Japanese Meteorite Newsletter, or the Meteoritical Bulletin. However, in a few cases it reflects differences of opinion about the proper way to classify the meteorite. The nomenclature used may also be modified by the editor to conform to an internally consistent classification scheme
The recommended classification eucrite means:
"An achondrite from the eucrite group."
The highlighted words are defined as follows:
achondrite: A stony meteorite that lacks chondrules and originated on a differentiated parent body.
eucrite: Eucrites are the most abundant type of basaltic achondrite, linked by geochemical traits such as oxygen isotopic ratios and certain elemental ratios, of which Fe/Mn is the most widely cited. The main minerals in eucrites are Fe-rich pyroxene and Na-poor plagioclase. The eucrites are strongly linked with the diogenites and howardites; the three groups are collectively known as HED meteorites and may come from asteroid 4 Vesta.
