| 11. | Antigorite Serpentine is another important water bearing phase that breaks down at eclogite facies conditions.
|
| 12. | Plagioclase is not stable in eclogite.
|
| 13. | Xenoliths of eclogite occur in kimberlite pipes of Africa, Russia, Canada, and elsewhere.
|
| 14. | Likewise, partial melting of eclogite has been modeled to produce tonalite-trondhjemite-granodiorite melts.
|
| 15. | Eclogite, a rock similar to basalt in composition, is composed primarily of sodic clinopyroxene and garnet.
|
| 16. | It also occurs in eclogite xenoliths from kimberlite as well as in crustal rocks metamorphosed at high pressures.
|
| 17. | Lower pressure, normally contact metamorphism produces albite-epidote hornfels while higher pressures at great depth produces eclogite.
|
| 18. | Transition into the eclogite facies is proposed to be the source of earthquakes at depths greater than 70 km.
|
| 19. | The eclogite melt may then react with enclosing peridotite to produce pyroxenite, which in turn melts to produce basalt.
|
| 20. | Commonly, only a few eclogite enclaves or UHP minerals reveal that the entire terrain was subducted to mantle depths.
