Paleotemperatures in the Central Alps, - an attempt at interpretation
- 203 Downloads
Paleotemperature data contain important information about the uplift history of a mountain range. A simple uplift model for the Gotthard region (Central Alps) is presented. This model satisfies the paleotemperature data but leads to unrealistically high temperatures at greater depths (lower crust, uppermost mantle). To improve the model additional crustal heat sources must be introduced which are assumed to be frictional heat sources caused by crustal overthrusting. This thermal problem also appears in other subregions of the Central Alps. Further problems are related to the thermal transition zone between adjacent crustal blocks with different uplift histories.
