📢A new paper from the @SupraterraUAB group, with collab. of @uni_mainz_eng researchers, explores fold to thrust nappes transition using #numericalmodelling. We show that hinge migration can explain km-scale overturned limbs observed in some fold nappes.

Extensional sandbox model with some interesting normal fault-related folding. A couple of sections contain 3 anticlines due to closely spaced faults in a transfer zone. Model uses a baseplate with irregular edge to create the transfer zone.
A new paper by Marc @Noneoidas (@UABBarcelona) explores the transition from fold to thrust nappes. Numerical models show that the hinge migration mechanism is viable to explain kilometric overturned limb observed in some fold nappes.

Two fold-thrust belt sandbox models reflecting (unbelievably) about the same amount of shortening. Buckle folds and minor, but very numerous, faults can accommodate a lot of displacement! Fault displacements in the lower model are huge but there are only two major structures.

A small snapshot of some of the geological features observed today. I'll share a more comprehensive overview another time. Here's some domino type boudinage and folding in Devonian (Mylor slate?) deformed during the Variscan orogeny. Photo near Mounts Bay, Cornwall #geology
