| Caption: | Limestone, Portsoy Group. Broadland Quarry, between Drumdelgie and Broadland, 3.25 miles west-north-west of Huntly. Aberdeen. |
| Description: | Dark grey crystalline limestone, composed of calcite of varying grain, ranging from 3.0-0.5 mm across, and elongated in the foliation planes, with rather intricate interlocking between the calcite grains and between calcite and quartz. Quartz is present in subordinate amount (fully 5 per cent by eye estimation), in grains ranging from 0.5 to fully 2.0 mm in length. The large grains are intergrown with calcite. Phlogopite and opaque grains, which include pyrite, are abundant accessories. Limestone with quartz, coarse- to medium-grained, granoschistose and grain-foliated. SL0240. Britrocks S35273. Magnification x40. Light PPL. |
