| Caption: | Loch Tay Limestone. Quarry 1300 yards east by south of Ronachan House, West Loch Tarbert. Argyll. |
| Description: | Sparkling grey medium-grained limestone. Composed of granular calcite of varying grain up to 2mm, with scattered small quartz and albite grains and muscovite flakes. Some less limey bands are composed of granulitic quartz and albite and irregularly prismatic crystals of clinozoisite cemented by granular calcite. The clinozoisite is charged with black powder (possibly carbon) and encloses also grains of pyrite. Pyrite occurs in large irregular grains, particularly in the quartz-feldspar bands of the rock, but is also present in small grains in the pure carbonate. Limestone with quartz, albite, muscovite and clinozoisite, heteroblastic, foliated. SL0147. Britrocks S34649. Magnification x40. Light XPL. |
