Understanding the Formation of Strata: Nesting Geophysical Data Sets for Interpretation of Key Stratigraphic Horizons in Shelf and Slope Deposits.

摘要

The ongoing goal for the second year of this project is to provide a model for correlating seismic reflection data of varying resolutions from continental margin regions in the context of understanding the stratigraphic evolution of shelf and slope deposits. Specifically this is applied to on-going work in the Eel River Basin, California. Our goal is to provide correlations between seismic data of various resolutions in order to constrain coring sites on the continental shelf and upper slope. This correlation can provide a tool for interpreting the stratigraphic surfaces and sequences of shelf and slope deposits, and can help to address the goal of mapping the stratal geometries in an active forearc basin. Although the very high-resolution seismic data may not have large regional coverage, correlations with lower resolution datasets could extend the interpretation over larger regions. The very high-resolution data may also provide a link relating sedimentary core samples to lower resolution seismic data. This work will provide an important resource for selecting coring locations, in order to address key scientific questions to improve our understanding of how sedimentary and erosional processes relate to characteristic stratigraphic sequences
