Definition of xenocryst in English:

xenocryst

nounˈzɛnə(ʊ)krɪstˈzēnə-

Geology

A crystal in an igneous rock which is not derived from the original magma.
〔地质〕异晶，捕获晶
Example sentencesExamples
- The xenocrysts provide evidence that earlier Neoproterozoic rocks were present in the region and that locally rocks date back to 1929 Ma.
- We interpret these grains as xenocrysts from an older source terrain from which the granitic protolith of sample MS 3 may have been derived by anatectic melting.
- Xenoliths, which are pieces of wall rock, or xenocrysts, which are single mineral grains that originate from xenoliths, can commonly be recognized at outcrops of magmatic rocks.
- Again, the lack of zircon xenocrysts in this sample does not allow discrimination between these alternatives.
- This could represent a xenocryst derived from Archaean basement rocks of the region.

Derivatives

xenocrystic

adjectivezɛnə(ʊ)ˈkrɪstɪk

Geology

Many of the intrusions contain veins and irregular patches of xenocrystic hybrid rock and granite.
Example sentencesExamples
- These are interpreted as xenocrystic cores and are of a similar age to zircon analysed elsewhere in the Anatolide belt of western Turkey.
- The remaining analyses can be represented as a single population at 603 + / - 3 Ma, but this would be a population of xenocrystic cores within the magmatic grains.
- There is also a subpopulation of subrounded xenocrystic zircons, which are slightly more brown than euhedral grains.
- Care was taken to sample the middle of the largest intrusion, to avoid contamination by xenocrystic component from the surrounding host rocks.

Origin

Late 19th century: from xeno- 'foreign' + crystal.
