Analogue modeling of detachment fault systems and core complexes: comment and reply
Article Abstract:
The model formulated by J.-P. Brun et al on the development of metamorphic core complexes and detachment faults does not discuss the denudation of the lower plate due to the action of large, low-angle normal faults. The existence of large subhorizontal shear zones which contain lateral deformations are also not taken into account. Plutons located at the lower plate could also produce the structure of the primary shear zone without encountering the rheological problems contained in the model.

Pluton emplacement during transpression in brittle crust: new views from analogue experiments: comment and reply
Article Abstract:
The analogue model for pluton emplacement developed by a group of geologic experts was criticized for its lack of relevance in explaining tectonic deformation. The proposed model makes use of sand and silicone putty in representing faults and shear zones that take place during regional contraction. This assumption, however, may not hold true for a number of occasions since anisotropic and temperature-related effects are likely to hinder the formation of silicone putty.

A shortened intraplate rift system in the Proterozoic Mount Isa terrane, NW Queensland, Australia
Article Abstract:
The rifting history of the Leichhardt River Fault Trough is documented through a reconstruction of its stratal architectures and original extensional tilt block geometries. It is shown that there were at least five major periods of extensional faulting between around 1800 and 1600 Ma, leading to the development of complex intracontinental rift system. A close spatial correlation between early extensional and later compressional structures is established.
