Simon Stewart's North Sea Diapirs - 2 interpreted Interpretation

VSA Author: Simon Stewart
Date Created: 2008-02-05

This section from the Central North Sea shows a vertical section through a diapir in the region. Salt interpretation filled in pink. Possible onlapping reflector geometry is identified at the crest of the diapir. This diapir was dominated by a phase of increasing and then decreasing salt flow rate relative to sedimentation rate that results in a classic teardrop shaped diapir. The crest is some 1000 m below sea bed, and appears to have been extinct since burial. From: Stewart, S.A. 2007. Salt tectonics in the North Sea Basin: a structural style template for seismic interpreters. In: Ries, A.C. et al. (eds). Deformation of the continental crust: the legacy of Mike Coward. Geol Soc.
