Definition of Xenocrysts. Meaning of Xenocrysts. Synonyms of Xenocrysts

- on the Earth's surface. A xenocryst is an individual foreign crystal included within an igneous body. Examples of xenocrysts are quartz crystals in a silica-deficient...
- another magma; these crystals are called xenocrysts. Diamonds found in kimberlites are rare but well-known xenocrysts; the kimberlites do not create the diamonds...

- pyroxenes and/or olivine phenocrysts are often found in more basic materials. Xenocrysts or rock fragments incorporated during the violent eruptional and depositional...
- after the hypothesized time of Earth's formation. In many other areas, xenocryst (or relict) Hadean zircons enclosed in older rocks indicate that younger...
- fragments (clasts) up to the size of watermelons. They are a mixture of xenocrysts and xenoliths (minerals and rocks carried up from the lower crust and...
