Dip map, Sinu prism central, offshore Colombia Regional Project

VSA Author: Rob Butler, Jamie Vinnels
Scenes: 9
Interpretations: 1
Date Created: 2010-01-28

Dip attribute map of the modern seabed, Sinu accretionary prism (offshore Colombia), created from merged bathymetric data. The associated interpretation gives locations for the various section profiles (scenes).

Date Created: 2010-01-28

Detail of a dip attribute map for the southern Sinu accretionary prism showing folding converging southwards, closing up the mini-basins. Note the incisional channel systems and significant mass wasting from the anticline limbs. A location map for associated "dog-leg" seismic profiles is available here as an interpretation.
