Short summary
We use seismic reflection data and quantitative fault analyses to examine how a sub-crustal lineament, the Sorgenfrei–Tornquist Zone, is expressed within upper-crustal rift systems off the shore of southern Norway. We document repeated reactivation of upper-crustal faults, displaying both sinistral and dextral oblique activity, which we link to underlying lineament and regional tectonics. We show how sub-crustal lineaments influence rift evolution and offer insights into past tectonic events.
