Mountain Belts on Subduction Zones |
|
|
|
The Andes is the best example of a mountain belt associated with a subduction zone. This belt is composed of folded and faulted mesozoic sediment (in blue) of an intracontinental basin deposited on top of a basement. This basement is made of |
|
|
| deformed Palaeozoic rocks on top of a proterozoic crust (pink). This belt started to develop 80 Ma ago. It presents a simple fan symmetry. The belt is intruded by long (up to 1000km) granitic batholiths, and covered by volcanic rocks. |
