Abstract

Detailed interpretation of seismic attributes along horizon slices or stratal slices reveals changes in depositional pattern and seismic geomorphology within a sediment column that are controlled by eustatic and local changes in sea level. In this study, we analyze seismic geomorphologic features of a shallow sedimentary column within a salt minibasin in the northern Gulf of Mexico, and attempt to predict the relative sea-level curves. We then calibrate these predictions against biostratigraphic markers and compare with existing eustatic cycles and events. Systematic analysis of amplitude and attribute data within a seismic geomorphologic framework reveals high-resolution sequence stratigraphic patterns that might otherwise be overlooked.
