| Caption: | Burdiehouse Limestone. Harbum Limestone Mine, 1 mile south of Harburnhead. Mid Lothian. |
| Description: | Compact earthy-brown, fine-grained limestone. Composed of minutely granular calcite, grain in general less than 0.002 mm, permeated by films of yellow bituminous matter. Complete and fragmentary ostracod shells, enclosing clear coarsely granular calcite are numerous. Grains of pyrite granules, occasional streaks of bitumen and traces of fossil phosphate are present. Some fine quartz grit occurs in certain laminae along with small aggregates of a radiating mineral which, in view of the chemical analysis, may be celestite. The rock powder on heating in the closed tube emits, a little oily vapour. Limestone, bituminous, pelitomorphic, microfossiliferous, bedded, homoiolithic. SL0054. Britrocks S34449. Magnification x40. Light PPL. |
