In the interpretation of structures from fragmentary subsurface geological data, the modelling attribute most commonly employed is that of model geometry or form. Other model attributes can provide insights to exploration-related problems associated with a structure. The nature of these attributes depends on the modelling approach (i.e. materials, boundary conditions, initial conditions); several are unique to a particular approach. The integration of data from several modelling approaches, each aimed at specific attributes, allows the most complete understanding of a structure. This leads to the development ol conceptual models of the origin, evolution and expression of structures as a function of initial conditions and boundary conditions. Such models provide 'rules of thumb' that guide interpretations in structurally complex areas. Laboratory and mathematical modelling attributes have been used here to improve our understanding of the deformation of the hanging wall above a thrust ramp.
