Use of a new artificial cohesive material for physical modelling: Application to sandstone intrusions and associated fracture networks

We focus in this paper on the emplacement of wing-like intrusions. We make use of a P.I.V (Particle Imaging Velocimetry) technique to analyse plastic deformation, showing that wing-like fractures open in mode I. A cone of vertical displacement was also recorded above the reservoir adding a shear component in the opening mode of wing-like fractures. These results have broad application to the emplacement mechanics of sandstone and igneous intrusions.
