| Caption: | Photomicrograph of a sample of Upper Limestone Formation Sandstone from one of the Drumhead quarries, Falkirk. |
| Description: | The image shows part of a thin section of a sample of Upper Limestone Formation Sandstone from one of the Drumhead quarries, Falkirk. The sample is held within the BGS Collection of Scottish Building Stones; British Geological Survey Petrology Collection sample number MC8569. The image was captured in plane-polarised light. Prior to thin-section preparation, the rock sample was vacuum-impregnated with a blue resin; in the resulting thin section, all of the pore space appears blue. The thin section image was captured using a Zeiss Axio Imager.A2m optical microscope with dedicated digital camera (Zeiss Axiocam 305 color) and ZEN image capture software. Magnification is by x2.5 objective lens: the field of view of images produced with this lens is 3.4 mm x 2.8mm. |
