| 21. | The aforementioned fractures were decisive in determining facies distributions during this interval.
|
| 22. | All these minerals were altered during the greenschist facies retromorphism.
|
| 23. | Comparison and classification of metamorphic facies is then determined for the sample.
|
| 24. | There are three different rock facies in the El Toro volcanic field.
|
| 25. | The eastern facies assemblage is thought to extend westward under the thrust plate.
|
| 26. | Mountain building begins in the late Paleogene, producing mostly continental sandstone facies.
|
| 27. | The lateral variation in sediment within a stratum is known as sedimentary facies.
|
| 28. | The slates are highly cleaved and metamorphosed as high as lower greenschist facies.
|
| 29. | The facies are glauconitic with some horizons of silicification.
|
| 30. | Hanging wall rocks at the Nalunaq Mine are Paleoproterozoic amphibolite-facies metavolcanics.
