Spon's Quarry Guide provides complete and up-to-date information on all of Britain's hard rock quarrying industry with its annual production of over 150 million tonnes of building stone, crushed rock, asphalt etc. For over 700 quarries it gives full address, OS Map Number and grid reference, telephone and contact names. Rock type, colour, grain and products are listed. The Guide also gives, for the first time in any publication, the plant and equipment at each quarry used for drilling, secondary breaking, load and haul and crushing. Details of offices and personnel are listed. Indexes allow the reader to identify key sources of information in the directory listings. Spon's Quarry Guide will be an essential reference for everyone in the quarrying industry, those who specify and purchase its products, those who supply plant equipment and services to the industry, and those who make commercial decisions about the companies involved.
