Some naturally formed folds in North Cornwall, England, show the following geometrical
features: 1.(a) each fold is noncylindrical; 2.(b) the profile shape varies along the hinge-line …

Plasticine rheology has been investigated in plane strain compression and stress relaxation
tests. Constant strain rate tests indicate Reiner-Rivlin fluid characteristics or alternatively the …

Experimental studies of single-and multilayer folding have generally considered shortening
of layers oriented perpendicular to the maximum extension direction X (ie layers parallel to …

Experiments on superposed folding were performed in a plane strain-pure shear rig using
paraffin wax as an analogue for rocks. A series of pre-formed cylindrical folds were refolded …

Buckle folds in internal multilayer systems will initiate and grow in a bulk plane strain
condition, in which the principal axis of no change, Y (X> Y> Z), is perpendicular to the …

The Leichhardt River Fault Trough of the Mount Isa Inlier comprises fault blocks which
exhibit different local deformational histories and structural orientations. Many structural …

Abstract Model experiments were specifically designed to test the effect of different profile
shapes of early folds on refolding patterns. Comparison of natural examples with …

The geometry of experimentally developed superimposed buckle folds with internal
tangential longitudinal strain in a single competent layer embedded in an incompetent host …

The visualisation of the intricate three-dimensional shapes that arise in non-coaxial refolding
is an ongoing problem in the study of multiply deformed terrains. Such complex forms also …

Physical models of superposed folds demonstrate that rheologic contrast strongly controls
the style of fold interference. Rheologic contrast affects strain partitioning between layer …
