Deformation, evolution and controls of halokinetic megaflaps driven by vertically-stacked and laterally-shifting depocenters Open
Megaflaps comprise steeply dipping to overturned panels of the oldest suprasalt strata flanking steep diapirs, and represent the roofs of early inflated salt. These large-scale structures result from salt-sediment interaction at minibasin …

Using salt diapirs and minibasins to constrain interpretations of crustal rifting and inversion in the Basque Pyrenees, Spain Open
Published interpretations across the Basque Pyrenees vary significantly in their depictions of rifting and subsequent inversion. Major points of disagreement relate to: (i) the asymmetry of the margin, i.e., whether the major extensional a…

Salt: The Rock That Flows Open
Salt is a substance with many uses, including as a condiment for our food. Salt is also a rock, and it can be found underground in many places around the world. What makes rock salt fascinating is that, over hundreds to millions of years, …

Do diapirs ever lose their heads? Insights from the Romanian Eastern Carpathians Open
<p>Numerous orogenic fold-and-thrust belts contain salt. It serves as an excellent d&#233;collement for folds and thrusts, and in some, diapirs had a profound influence on the structural styles. In salt-detached fold-and-thrust b…

Burial wedges—Evidence for prolonged progressive burial of the Paradox Basin salt walls—With a detailed example from Gypsum Valley, Colorado Open
Many Paradox Basin passive salt diapirs underwent a prolonged history (>65 my) of progressive burial during the Early Triassic to Jurassic. Burial is recorded by a series of geographically limited wedge‐shaped stratal panels of diapiric ro…

Influence of preexisting salt diapirs during thrust wedge evolution and secondary welding: Insights from analog modeling Open
Salt lithologies are mechanically weaker than other sedimentary rocks. Salt horizons usually act as décollements and precursor salt bodies preferentially deform early during contraction, concentrate deformation, and impact the structural s…

Different scales of salt-sediment interaction around passive diapirs Open
<p>Passive diapirism entails ongoing, near-surface syndepositional growth of a salt stock or wall. As such, the diapirs and intervening minibasins influence the development and geometries of associated sedimentary strata. In this sho…

Low-angle shear within the exposed Manzalesti salt diapir, Romania: incipient decapitation in the Eastern Carpathians fold-and-thrust belt Open
In salt-detached fold-and-thrust belts, contractional modification of salt structures may include decapitation by thrusting, but examples are not well known in the subsurface and unreported in outcrop. Here we present a surface exposure of…
