| Caption: | Shira Limestone. Turnalt Quarry. Argyll. |
| Description: | Dull grey, compact, but irregularly jointed limestone. Composed of granular calcite (0.05-0.1mm grain-size) and subordinate quartz and water-clear alkali-feldspar (0.1 mm grain). The grains have a tendency to be elongated parallel to a plane not recognizable in hand specimen. All minerals are recrystallized, but not to a high degree. Calcite-filled cracks cut steeply across the direction of elongation. Some thin streaks of turbid amorphous materials are present. Limestone with quartz and feldspar, fine-grained, granoschistose. SL0124. Britrocks S34572. Magnification x40. Light XPL. |
