Tibete, China
It was not a mega-crisis, but the climb of the cloak that caused the elevation of Tibet. New study revolutionizes tectonic models.
A new study challenges tectonic models that we have so far had as guaranteed: suggests that the elevation of Tibet was caused mainly by Post-collision cloak dynamicsand not for continuous convergence between India and Asia.
O, published this month in Earth-Science Reviewsseal-be not time two Syncholiation processes, in the extent of its spatial effects and structural and compositional differences between the syncholitory and post-collation characteristics.
Q elevation of the Tibetan plateau was after all driven mainly by the dynamics of the cloak that followed the collision, which occurred in the late cenozoic – it is not a uniform structure formed by a single collision process, and did not involve significant submergence From the Indian continent under the interior of the Tibet, explains the.
Seismic tomography and data of helium isotopes restrict the Indian continent’s subduction to depths of 200 to 300 km, mainly below the Yarlung-Zangpo suture, which marks the most southern margin of the Tibetan plateau, explains the study.
As paleomagnetic discrepancies Concerning the width of Great India are resolved by emphasizing coverage and foundation decoupling during smooth collision and shallow subduction, limiting its subduction to short distances of ≤300 km.
This study shows us that generic assumptions do not support themselves in a further analysis. It is necessary to examine the rationality of geodynamic models for the processes, warns the researchers. This scientific revolution shows in this way that the scientific models on which we are based can after all to be wrong – just look in more detail.
