| Bent specimens show folds on the compressional but not the extensional side, indicating that walls were originally flexible. |
| The range was formed in the extensional environment associated with the Mesozoic and Cenozoic breakup of Gondwanaland. |
| Development of pillow breccia probably occurred along the scarps of normal faults in this extensional setting. |
| The development of extensional and shear fractures in volcanic areas is usually related to magma emplacement at shallow crustal levels. |
| The metamorphic core complex is thus formed as mid-crustal rocks are exhumed by tectonic unroofing in an extensional setting. |
| He also questions the stratigraphy of the graben and the timing of north-south extensional tectonics. |
