Opis

2Gpa has increased to more than 15.
This indicates that subduction of continental fragments to depths of 100-150 km may have played a significant role in the formation of mountain belts.
This volume brings together the geochemical, geophysical and geodynamical approaches to study the processes active during ultrahigh-pressure (UHP) tectonics.
The collection of papers demarkates the frontier of our understanding of the creation, preservation, and exhumation of ultrahigh-pressure rocks.
Audience: This volume will be of interest to any earth scientist interested in ultrahigh pressure processes and the formation and modification of continental crust.
