Where a shear zone is bounded by undeformed wall rocks and there is no volume change,
the deformation path within the zone on the bulk scale approximates a simple shear. Where …

River avulsion as studied in small-sized and medium-sized rivers is partly explained by the
water surface gradient advantage of a new channel course over the old course, caused by …

Most of the 16 papers in this special issue were presented at a session entitled “The
recognition of trigger mechanisms for soft-sediment deformation” at the 27th IAS Meeting of …

Sandstone injections are created by the forceful emplacement of remobilized sand in
response to increases in overpressure. However, the contribution provided by horizontal …

Incised fluvial systems are typically interpreted as recording geologically recent changes in
either climate or tectonics. However, few diagnostic tools exist to evaluate whether particular …

This paper examines the stratal geometries and facies stacking patterns associated with
forced regressions around fault-propagation folds in extensional and compressional …

This paper describes the geometry and strain characteristics of a complex system of small
extensional faults affecting Lower Tertiary mudrock‐dominated successions throughout the …

We use new analogue modelling experiments to analyse the development of pull-apart
basins in an upper crust characterised by the presence of pre-existing discrete fabrics. As in …

In this paper we show that a quantitative analysis of remote sensing data allows the
localization of active deformation and the quantification of strain intensity and kinematics. As …

Fault-propagation folding is a common folding mechanism in thrust-and-fold belts and
accretionary prisms. Several geometrical models relating the fold shape to the ramp shape …
