Abstract

Seven Albian sea-level curves from localities around the globe have been correlated on the basis of the number and timing of transgressive-regressive cycles shown. The localities chosen were considered to have been tectonically 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 demonstrated with the present stratigraphic resolution. Frequency trends show that Albian sea level was statistically stable from the late early to the early late Albian, whereas it fluctuated rapidly in earliest and latest Albian.
