During this period of initial flooding the new sea is sensitive to changes in climate and eustasy. |
Tectonics and eustasy were the two main controls on platform development. |
This study demonstrates efficacy of interregional correlation of sea-level changes for resolution of the problem of the alternative views of the Jurassic eustasy. |
Subtidal, carbonate and carbonate-clastic symmetric cycles are interpreted to form when the long-term, tectonically driven eustasy prevails over glacioeustasy. |
Eustasy is defined as a global sea level change when referenced to a fixed datum, for instance the center of the earth. |
Despite some datation uncertainties and the unknown durations of Lower Jurassic cycles, middle frequency sequences appear to be controlled by eustasy. |
