| Lithological Description: |
Quartzite, cross-bedded, granular, white; large-scale ripple marks prominent. |
| Definition of Lower Boundary: |
Sharp change from thinly-banded psammite and semipelite to thick-bedded quartzite. |
| Definition of Upper Boundary: |
Top of highest quartzite bed; overlain by flaggy thin-bedded psammite and semipelite. |
| Thickness: |
c.7m on coast section; possibly 10 to 20m inland. |
