Simon Stewart's interpretation of N Sea inversion structure 1. Interpretation

VSA Author: Simon Stewart
Date Created: 2008-02-20

An example of a seismic structure that has been described as being related to inversion, but which may not fit into the classic interpretation of inversion tectonics. This seismic section is from a half graben in the North Sea in which the hanging-wall pre-rift section (partly obscured by multiples) subcrops the post-rift. The post-rift section is uplifted above the regional elevation. In the interpretation, orange shading corresponds to Triassic sediments. Published in: Stewart, S.A.
