non-cylindrical deformation. Asymmetry of the postorogenic extension could be correlated with the amount of stretching. Rather symmetric deformation seems to occur in marginal areas of the domain while asymmetric deformation is encountered within highly-extended areas where lower crustal material is exhumed within MCCs.

Extensional tectonics in the Caledonides: Synorogenic or .

Although synorogenic extension is likely to have occurred, large‐scale synorogenic extensional collapse models in the Caledonides are at present difficult to prove, whereas impressive postorogenic multi‐stage extension is beautifully portrayed.

Open Research: Termination of the Permo-Triassic Songrim .

This paper presents new geochemical and SHRIMP U-Pb zircon ages for two alkali granites that postdated the Songrim Orogeny in the Ogcheon belt. Both granites are contemporaneous (219.3 ± 3.3 Ma and 219.6 ± 1.9 Ma) and are geochemically post-orogenic A-type granites intruded in an extensional setting subsequent to a major collision.
