| Caption: | Kirkby's V Limestone. Shore at Randerston. Fife Region. |
| Description: | Brownish-buff massive rock which in some bands is almost wholly composed of shells. In thin section the shells are seen to be cemented by a matrix of fine granular clear carbonate in which are set numerous granules of oxidized siderite (0.01 - 0.02 mm), angular quartz grains (0.1-0.5 mm) and a few yellow phosphatic fossil fragments. A few small cavities are filled with kaolin. The carbonate replacing the shells is an ankerite the refractive index of which is variable being generally between 1.690 and 1.700 but as high as 1.705, and the fine-grained carbonate of the matrix is similar. Ferriferous dolomite, arenaceous, sideritic, micrograined, zoichnic. SL0030. Britrocks S34452. Magnification x40. Light PPL. |
