Caption: Photomicrograph of sandstone from Pawson Quarry, Leeds, West Yorkshire, England
Description: The image is a photomicrograph of part of a thin section of sandstone viewed in order to highlight the different mineral components present in the rock. The specimen is of Carboniferous age. British Geological Survey Petrology Collection sample number MC 5827. The sample is a quartz sandstone with a carbonate matrix cement, and common iron oxides scattered throughout. The quartz grains are generally white in thin section. They show a range of sizes and shapes. The carbonate matrix is visible as yellowish grainy patches which infill much of the primary porosity in the sandstone. In thin section iron oxide appears very dark and opaque. Woodkirk stone is commonly used in Scotland for the repair of stone buildings. It has a distinctive greenish-grey appearance, and has a relatively fine grain size. One advantage of Woodkirk stone is its ability to be relatively easily worked by stone masons.
