Definition of eustasy in English: eustasynoun ˈjuːstəsiˈjustəsi mass nounA change of sea level throughout the world, caused typically by movements of parts of the earth's crust or melting of glaciers. Example sentencesExamples - Such changes are not as rapid as those associated with glacio and geoidal eustasy but over a prolonged time period (perhaps longer than the Quaternary) they could have had a major impact on the level of the world's oceans.
- Moreover, glacial eustasy is rejected because of the lack of evidence for widespread glaciation at the appropriate stratigraphic level and because the required kilometre-scale drawdown far exceeds that expected through glaciation.
- Within this rhythm, alternations between PDF and WDF units record the interplay between sediment supply, basin subsidence, climate and eustasy, which caused repeated minor progradational and retrogradational rhythms.
- Such variables, on a shallow marine carbonate platform developed upon a passive margin, are essentially represented by eustasy, climate, subsidence and sedimentation rate.
- Coastal ecosystems have been forced to migrate staggering distances since the waning of Pleistocene glaciers began to drive the postglacial rise in global sea level, termed eustasy by geologists.
Origin 1940s: back-formation from eustatic, coined in German from Greek eu 'well' + statikos 'static'.
