Interpreting a deepwater thrust system: offshore Namibia Scene

VSA Author: Rob Butler
Interpretations: 1
Date Created: 2021-02-18

This image can be used as a simple interpretation exercise in structural geology. There is a debrief pdf in the doc and links that goes through an interpretation workflow - leading to the associated interpretation uploaded here. The aim here is to build an interpretation of stratigraphic horizons through a thrust belt. Three horizon are identified. trace these through the array of thrusts. You’ll need to pick thrusts and match up horizons, considering the patterns of displacements required by your interpretation as you build it. You should be able to trace the horizons through the entire image. You could attempt to restore your interpretation to examine whether it “works” (assume V=H).

An interpretation of a deepwater thrust belt. See associated scene if you'd like to use this to run a simple seismic interpretation exercise. The clean "scene" has, via its docs and links, a pdf that goes through an interpretation workflow and it is discussed in a video on "The Shear Zone" YouTube channel (access via "docs and links").
