| 1. | All these minerals were altered during the greenschist facies retromorphism.
|
| 2. | The greenschist, whose colour comes from harbour wall, are now closed.
|
| 3. | The slates are highly cleaved and metamorphosed as high as lower greenschist facies.
|
| 4. | They consist of interlayered sedimentary and volcanic flow rocks metamorphosed to low greenschist facies.
|
| 5. | Incorporated at the base of the greenschist are limestone lenses containing upper Silurian conodonts.
|
| 6. | A shield is that part of the metamorphosed greenschist, amphibolite, and granulite facies.
|
| 7. | Oligoclase is also found in metamorphic rocks formed under transitional greenschist to amphibolite facies conditions.
|
| 8. | In greater detail the greenschist facies is subdivided into subgreenschist, lower and upper greenschist.
|
| 9. | In greater detail the greenschist facies is subdivided into subgreenschist, lower and upper greenschist.
|
| 10. | The greenstone belts of the various archean cratons are commonly altered to the greenschist facies.
