Vitrinite reflectance analysis and the mean diameter of metamorphosed quartz, suggest that the eastern Ouachita region, Arkansas, USA reached the lower greenschist facies, regardless of burial depth. An increase in “crystallinity” may explain tha

Chamberlin (1910) was the first to quantitatively predict the shape and position of a basal detachment from detailed surface observations. His predicted detachment beneath the Appalachian Valley and Ridge fold-thrust belt of central Pennsylvania is s

By examining a vein from its tip to center, we have established the transition from a single filled fracture at the vein tip to typical ‘crack-seal’ textures observed in fibered, laminated veins. The vein is contained in the boudin neck of a sand

The Twin Creek Limestone in the footwall of the Absaroka thrust sheet contains three sets of bed-normal syntectonic calcite veins. Vein formation occurred during Cretaceous motion along the Absaroka thrust fault as indicated by (1) crosscutting relat

We use two suites of lithospheric-scale physical experiments to investigate the manner in which deformation of the continental lithosphere is affected by both (1) variations of lithospheric density (quantified by the net buoyant mass per area in the

Collisional mountain belts are characterized by fold and thrust belts that grow through sequential stacking of thrust sheets from the interior (hinterland) to the exterior (foreland) of the mountain belt1,2,3,4,5. Each of these sheets rides on a faul

Duplexes are a common feature in thrust belts at many scales. Their geometries vary significantly from antiformal stacks with significant forethrusting in the cover (e.g. southern Pyrennes, Spain) to triangle zones (e.g. foreland Canadian Rockies) to

Multi-layered calcite veins in a dilatant jog of a left-stepping, left-slipping shallowly buried fault segment are composed of alternating millimeter- to submillimeter-thick calcite veinlets and host lithons forming a coarse ‘crack–seal’ textur
