TL;DR: In this paper, a hierarchical stacking of depositional sequences of shallow-water, carbonate-dominated sedimentary systems was studied in the Swiss and French Jura, in Spain, and in Normandy, showing that sea-level fluctuations were an important factor in their formation.

TL;DR: In this paper, two regionally significant microbial-foraminiferal episodes (∼150 kyr each) occur within the Early Aptian shallow marine platform in Oman and throughout eastern Arabia and are coeval with oceanic anoxic event 1a (OAE1a; Livello Selli).

TL;DR: In this article, three orders of depositional sequences are defined (third to fifth order) and correlated between sections over the course of three third-order sequences, covering the Barremian to Lower Aptian, a thirdorder depositional pattern is documented that consists of a succession of three distinct faunal assemblages: discoidal orbitolinids and calcareous algae were deposited during early transgression; microbialites and microencrusters dominated the late transgressive to early highstand facies; and a rudist and milioliddominated facies is typical

TL;DR: The origin of third-order depositional sequences remains debatable, and in many cases it is not clear whether they were controlled by tectonic activity and/or by eustatic sea-level changes.
