| 11. | The Torlesse Greywacke has undergone metamorphism and been transformed into Haast Schist.
|
| 12. | Most likely these metagreywackes only have undergone a higher degree of metamorphism.
|
| 13. | Its typical occurrence is in shales that have undergone low grade metamorphism.
|
| 14. | Dating fractionating zonation thus help putting time constraint on metamorphism.
|
| 15. | Frequently, rock formations that undergo orogeny are severely deformed and undergo metamorphism.
|
| 16. | Conversely, decreasing temperatures and pressure characterize " retrograde metamorphism ".
|
| 17. | The Roxbury Conglomerate has been significantly altered by metamorphism.
|
| 18. | It has not undergone metamorphism and is often yellowish with visible embedded fossils.
|
| 19. | Shock metamorphism in the Azuara impact structure include planar deformation features in quartz.
|
| 20. | The batholith has caused metamorphism on its western edge.
