| Caption: | Tayvallich Limestone. Fincharn Quarry, at south end of Loch Awe. Argyll. |
| Description: | Dark grey sparkling limestone, of medium grain, containing small aggregates of white calcite. Composed of granular dusty calcite, 0.4 mm grain, partially recrystallized to clear calcite, forming lenticular aggregates in a finer-grained rock, of mixed dusty and clear calcite grains, 0.1 mm, showing foliation which curves round the lenticles. The foliation is shown by elongation of grains and by alternation of coarser and finer laminae with streaks of carbonaceous matter. Quartz occurs as an essential but subordinate constituent, as large grains partly recrystallized along with calcite, sometimes showing regrowth rims, partly as lenticular aggregates of smaller grains, and to a subordinate extent interstitial in the coarser dusty limestone. Limestone with some quartz, grain-foliated and granoschistose. SL0126. Britrocks S34574. Magnification x40. Light XPL. |
