| Lithological Description: |
Calcareous and non-calcareous semipelite at base passes upwards into well-bedded tremolitic dolomite. At top dolomite passes upward into semipelite and fine-grained psammite before upper boundary with Schiehallion Quartzite is reached. |
| Definition of Lower Boundary: |
Sharp change from quartzite to calc-semipelite and non-calcareous semipelite. |
| Definition of Upper Boundary: |
Change from finely-bedded semipelite to well-bedded quartzite. |
