Abstract: 
Flower structures are amongst interesting phenomena in structural geology, whose three-dimensional understanding and interpretation are a bit difficult. In order to resolve this problem, a three-dimensional model has been represented, in which the type and direction of fault block movements both in plan view and cross section can be observed.
Two horizontal and vertical quadratic prisms of the same size are cut to resemble the flower structure.
The contact faces of the cut blocks are covered by glossy paper so as to reduce friction and facilitate their motion. The two quadratic prisms are then placed in a glass box and are pushed by wooden levers. The design of the model is such that only shearing forces act with no tensile or compressive components.
The result from such set-up is that even in regions with only shearing tectonic regimes transtensional and transpressional structures form.
