Title: Fluctuating Mesozoic and Cenozoic Sea Levels and Implications for Stratigraphy: ABSTRACT

Author(s): Bilal U. Haq

Article Type: Meeting abstract

Abstract:

Previous HitSequenceNext Hit stratigraphy encompasses depositional models of genetically related packages of sediments deposited during various phases of cycle of sea level change, i.e., from a lowstand to highstand to the subsequent lowstand. The application of these models to marine outcrops around the world and to subsurface data led to the construction of Mesozoic-Cenozoic sea level curves with greater event resolution than the earlier curves based on seismic data alone.

Construction of these better resolution curves begins with an outline of the principles of Previous HitsequenceNext Hit-stratigraphic Previous HitanalysisNext Hit and the reconstruction of the history of sea level change from outcrop and subsurface data for the past 250 Ma. Examples of marine sections from North America, Europe, and Asia can be used to illustrate Previous HitsequenceNext Hit Previous HitanalysisNext Hit of outcrop data and the integration of chronostratigraphy with sea level history.

Also important are the implications of Previous HitsequenceNext Hit-stratigraphic methodology and the new cycle charts to various disciplines of stratigraphy, environmental reconstruction, and basin Previous HitanalysisNext Hit. The relationship of unconformities along the continental margins to hiatuses and dissolution surfaces in the deep basins must also be explored, as Previous HitwellNext Hit as the relevance of Previous HitsequenceTop-stratigraphic methodology to biofacies and source rock prediction.
