Although lowstands of sea level greatly favor the development of deep-sea fan systems, the timing and type of turbidite events in these systems may depend not only on the sea-level changes but also on the nature of available sediments, tectonic setting, size, and gradients of the basins. Thus, in basins with steep gradients, located on continental or transitional crust or along active margins close to sedimentary sources that could supply coarse-grained sediments, unchannelled turbidite sand lobes detached from updip channels or valleys might have been deposited during lowstands of sea level. Channel-attached sand lobes and channel levee complexes might have been deposited during sea-level rises in these basins. In contrast, large fan systems, such as the Indus Fan, located off passive margins in oceanic basins with flat gradients, distant sedimentary sources, and a predominantly fine-grained sediment supply have channel-attached lobes and channel levee, overbank complexes that were probably deposited during lowstands and to some extent during highstands of sea level.

Sea-Level Changes: An Integrated Approach
Sea-Level Changes: An Integrated Approach - In October 1985, SEPM sponsored a four-day conference entitled ?Sea-Level Changes ? An Integrated Approach.? The purpose of the conference was to provide a forum for an interdisciplinary exchange of ideas on sea-level changes and to provide an opportunity for integrating various types of evidence in approaching unresolved issues. The conference was successful in bringing together scientists from industry, academia, and government, representing all of the major geosciences disciplines. Presentations of many new papers, plus significant releases of data that were previously held proprietary, provided fertile ground for discussion. This much-cited volume represents the best of the material presented at the conference. Includes the early ?Vail? chart.
