Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A stony meteorite of a kind consisting largely of pyroxenes and plagioclase.
- ‘The exception is a group of meteorites called howardites, eucrites, and diogenites (nicknamed HED meteorites).’
- ‘Because diogenites have a coarse-grained texture with large interlocking crystals, however, they must have cooled more slowly than the eucrites.’
- ‘The dark ‘shock’ lines are characteristic of this diogenite.’
- ‘Unbrecciated diogenite that shows orthopyroxenes and chromite grains that are partially fragmented and deformed.’
- ‘The Johnstown meteorite is classified as a calcium-poor diogenite, being composed mainly of hypersthene, with minor amounts of plagioclase and olivine.’
- ‘Together, the howardites, the eucrites, and the diogenites form the most abundant class of achondrites in our collections.’
- ‘This analysis suggests that we have discovered the first polymict diogenite - a true scientific sensation.’
- ‘In addition, individual fragments of eucrites and diogenites are often found within the howardites.’
- ‘This photo of a diogenite is magnified 40 times - exactly the same amount as the eucrite.’
- ‘Howardites are polymict breccias composed of angular clasts of eucrites and diogenites welded together by pulverized mineral dust.’
- ‘In order to preserve the observed zoning profiles, NWA 4215 clearly cooled significantly faster than other diogenites.’
- ‘This research represents a continuing effort to understand the petrogenesis of diogenites and their relationship to eucrites.’
Late 19th century: from Greek Diogenēs ‘descended from Zeus’ + -ite.
