Definition of ejecta in English:

ejecta

plural noun ɪˈdʒɛktəəˈdʒɛktə

Geology Astronomy

often treated as singular Material that is forced or thrown out, especially as a result of volcanic eruption, meteoritic impact, or stellar explosion.
〔主地质，主天文〕（尤指火山喷发、陨星撞击或恒星爆炸时的）喷出物，排出物
Example sentencesExamples
- Fresh impact craters are surrounded by fluidized ejecta patterns, likely produced by impact into subsurface water and ice.
- From the impact ejecta volume, he calculated a crater size of around 150 to 200 meters.
- Melosh et al. proposed that wildfires were ignited by the thermal energy radiated by re-entering ejecta following the asteroid impact.
- Their discovery of shocked quartz grains in a sandy layer in a Georgia kaolin mine documents the scatter of ejecta from the Chesapeake impact site.
- The larger masses of molten glass remained near the effusive center; these were slower to solidify and commonly became strange agglomerations where bombarded by the rain of smaller ejecta.
- The ejecta are still moving rapidly, however, and quickly sweep up surrounding matter to form a shell that slows down as mass gets accumulated, an action similar to that of a snowplow.
- Impact ejecta deposits show a non-linear decrease in thickness with radial distance from the centre of the source crater.
- The stellar ejecta from the explosion initially trail behind the shock wave.
- Behind the nucleus, a broad fan of impact ejecta, backlit by the Sun, spreads out into space.
- This could account for the finer ash layers in the quarry sequence being dominated by T2 ejecta.
- You can also see the ejecta blanket, material that has been tossed out’ of the crater.
- Many craters are characterized by large lava-flow-like features that may represent molten ejecta flowing outward from the crater after the impact.
- The anomalous platinum group element geochemistry of the ejecta horizon suggests that the impactor was an asteroid.

Origin

Late 19th century: from Latin, 'things thrown out', neuter plural of ejectus 'thrown out', from eicere (see eject).
