THE CONTROL OF TERMINAL-SPLAY SEDIMENTATION ON DEPOSITIONAL PATTERNS AND STRATIGRAPHIC EVOLUTION IN AVULSION-DOMINATED, UNCONFINED, DEEP-MARINE BASIN-FLOOR SYSTEMS

摘要

Recent improvements in seismic resolution and more detailed outcrop mapping of basin-floor fans has shown that they are made up of a hierarchy of discrete building blocks. The most fundamental building block, made up of one or several event beds, is termed a stratal element. These elements stack to form lobes, which in turn stack to form lobe complexes and ultimately the fan. The arrangement of the building blocks on the fan is driven by channel avulsion, and the location of the avulsion defines the hierarchy.
