Antigorite Serpentine is another important water bearing phase that breaks down at eclogite facies conditions.
2.
Transition into the eclogite facies is proposed to be the source of earthquakes at depths greater than 70 km.
3.
Another important water producing reaction that occurs during the eclogite facies is the dehydration of the hydrous phyllosilicate phlogopite by the reaction below.
4.
High-ultrahigh pressure metamorphic path through the zeolite, prehnite-pumpellyite, blueschist, and eclogite facies stability zones of subducted oceanic crust.
5.
Using U-Pb dating, estimated the timing of eclogite facies metamorphism, a process which require transport to mantle depth, to 1.904 Ga.
6.
The metamorphic transition from mafic granulite facies to the denser eclogite facies in the lower portion of the crust is the main mechanism responsible for creating negative buoyancy of the lower lithosphere.
7.
They consisted originally of a sequence of deep-marine ( flysch ) sediments of Ordovician to Devonian age ( 480-360 million years old ) and early Paleozoic eclogite facies ).
