| Caption: | Sgurr nan Clach Geala, (1093 m.) from the north, Fannich Forest, Ross & Cromarty. Mountains of Moine Supergroup psammite and pelite, well-foliated. Joint planes and crush-lines forming lines of erosion and giving rise to gashes in rock face. |
| Description: | Sgurr nan Clach Geala, (1093 m.) from the north, Fannich Forest, Ross & Cromarty. Mountains of Moine Supergroup psammite and pelite, well-foliated. Joint planes and crush-lines forming lines of erosion and giving rise to gashes in rock face. Steep slopes on left side of mountain largely made of flaggy, micaceous psammite (metamorphosed sandstone) while summit ridge is made of pelite (metamorphosed mudstone). Lithological units on map strike north-south and are steeply inclined, but subhorizontal features on steep slopes look like bedding. Rock is cut by abundant subvertical joints and ?minor faults. |
