| Eustasy is defined as a global sea level change when referenced to a fixed datum, for instance the center of the earth. |
| The wedge-shaped geometry, the thickness variation and the stacking pattern of the Guadagnolo succession are the response to eustasy and tectonic subsidence. |
| Despite some datation uncertainties and the unknown durations of Lower Jurassic cycles, middle frequency sequences appear to be controlled by eustasy. |
| 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. |
| However, it must be noted that the global sea level fluctuations represent a combination of factors such as eustasy, subsidence and sediment supply. |
