| 11. | The volcanogenic material was metamorphosed to leptynites and amphibolites.
|
| 12. | The graptolite-bearing shales were later metamorphosed into lower amphibolite facies slates.
|
| 13. | The defomration associated with the orogeny can be seen in amphibolite facies metamorphism.
|
| 14. | At the veins in amphibolites and ultramafic rocks.
|
| 15. | The metasedimentary rocks are quartz-rich and the amphibolites represent mafic igneous intrusions.
|
| 16. | Prehnite-pumpellyite facies to mid-amphibolite facies have been produced by metamorphism.
|
| 17. | Mineral chemistry and thermobarometry of a southern Appalachian amphibolite with epidote + quartz symplectite.
|
| 18. | The land is composed of paragneiss of amphibolite and orthogneiss dated 1 billion years.
|
| 19. | It is the principal mineral of amphibolites.
|
| 20. | Some show granulite facies metamorphism, but most are the slightly lower temperature amphibolite facies.
