| Dynamic aspects of continental breakup: Why do continents break ? : Active vs Passive Rifting ... |
||||||||
| Passive rifting => Plate boundary forces: Tectonic forces applied at plate boundaries trigger lithospheric thinning, mantle decompression and melting. In the passive rifting dynamic mode, melting postpones the onset of extensional tectonics as mantle upwelling is a passive response to tectonic forces. | ||||||||
