| Caption: | Islay Limestone. In angle of main road and Persabus road, 2 mile west-south-west of Port Askaig. Argyll. |
| Description: | Grey compact and crystalline banded limestone which seems to have a poor cleavage at a low angle to the banding. Numerous patches and wisps, often contorted but with a general parallel orientation, of dark, very fine-grained limestone in a recrystallized granular base of calcite, illustrate palimpsest structure. The grain of the base is about 0.03 - 0.1 mm and small crystals of albite, about 0.1 mm across, are scattered through it. Small crystals and grains of pyrite appear in both the dark patches and the base. Limestone, fine-grained foliated, palimpest. SL0132. Britrocks S34580. Magnification x40. Light PPL. |
