Caption: Dolomite vein in Burdiehouse or Grange Limestone. Newbigging Mine. Fife Region.
Description: Brown dolomite with lustrous crystalline surfaces, composed of an aggregate of anhedral ankerite of uniform grain 0.1 - 0.2 mm size, and of a uniform pale brown tint. Sporadic, small oval areas of clear carbonate including calcite represent ostracods. The ankerite in the section and in powder appears to be homogeneous, omega = 1.707 corresponding to about 12 per cent FeO. These figures agree well with the chemical analysis considering that free calcite is present. The rock has a small proportion of empty pore spaces. Small aggregates of pyrite granules are present. Ferriferous dolomite, fine-grained, uneven mosaic. SL0172. Britrocks S34856(f). Magnification x40. Light PPL.
