Global correlation of middle Cretaceous sea-level events

Seven Albian sea-level curves from localities around the globe have been co rrelated on the basis of the number and timing of transgressive-regressive cycles shown. The localities chosen were considered to have been tectonical ly stable. There are 11 time lines placed in the different sections by use of graphic correlation. They are based on the position of European ammonite zonal-subzonal boundaries projected into sections in North America and the Middle East, The examined sea-level sequences (with durations of 0.3-2.7 m .y.) appear to vary regionally, and their global correlation cannot be demo nstrated with the present stratigraphic resolution. Frequency trends show t hat Albian sea level was statistically stable from the late early to the ea rly late Albian, whereas it fluctuated rapidly in earliest and latest Albia n.
