Exempel på hur man kan använda CHONDRITIC i en mening

• Geochemical evidence suggests that the impactor was likely a chondrite asteroid or a comet with a chondritic component.
• 1 grams, the meteorite's exterior is fully crusted, showcasing regmaglypts, while its interior reveals a light-gray chondritic texture.
• Carbonaceous chondrites or C chondrites are a class of chondritic meteorites comprising at least 8 known groups and many ungrouped meteorites.
• The CK chondrites, a group of carbonaceous chondrite (which are a class of chondritic meteorite) were named for this meteorite.
• Wasson (2003) – For important studies on the classification, origin, and early history of iron meteorites and chondritic meteorites, and on the mode of formation of chondrules.
• It is a chondritic type, but the samples showed unusual radionuclide profiles when analyzed in 1962: the Michigan State University sample was unusually high in potassium (higher than any other chondrite), rubidium (higher than any other meteorite), and caesium, while the Smithsonian Institution sample uniquely contained measurable amounts of Radium-226 and its decay products, suggesting contamination.
• The researchers found that the fragments from the crater zone had a chondritic texture and the following mineral composition: pyroxene (1) 40%, olivine 20%, feldspar 10%, pyroxene (2) 10%; kamacite 15%, troilite 5%, and traces of chromite and native copper.
• Chondrules and calcium–aluminium-rich inclusions (CAIs) are spherical particles that make up chondritic meteorites and are believed to be the oldest objects in the Solar System.
• This reveals a dark matrix embedded throughout with mm-sized, lighter-colored chondrules, tiny stony spherules found only in meteorites and not in earth rock (thus it is a chondritic meteorite).
• Most asteroids formed inside the snow line from mostly chondritic planetesimals and protoplanets over 4.
