Description: | Large grains of twinned calcite are closely interlocked and tend to be elongated parallel to the foliation. Small quartz grains and muscovite flakes are scattered sparsely through the calcite. In bands there is a considerable concentration of tremolite, patched by crocidolite, and phlogopite which are orientated with their long axes parallel to the plane of foliation. Grains of oxidized iron ore and trains of limonitic material occur; there are many small grains of yellow pyrite, and acute lozenges of sphene are accessory. Limestone with phlogopite and tremolite, coarse-grained, foliated, grano-schistose. SL0107. Britrocks S34586. Magnification x40. Light PPL. |
