| Caption: | Bilston Burn (No. 3) Limestone (?), deep seated, weathered limestone. Quarry, Esperston Limeworks, 660 yards north-east of Esperston. Mid Lothian. |
| Description: | Pale buff, very fine-grained limestone with brown bituminous films. Composed of finely granular calcite (0.01 mm grain) enclosing numerous shell fragments which are often flat or flattened along the bedding. Clay is sometimes recognizable in small aggregates as kaolin. Quartz is rarely distinguishable as small grains, 0.01 mm, but many feebly birefringent aggregates may be more finely divided quartz. Shreds of bituminous and limonitic matter are common and limonite replaces scattered rhombs of siderite. Limestone, argillaceous, micrograined, fossiliferous, clastizoic, bedded. SL0045. Britrocks S34534. Magnification x40. Light XPL. |
