Spon's Quarry Guide provides complete and up-to-date information on all of Britain's hard rock quarrying industry. 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 used at each quarry used for drilling, secondary breaking, load and haul and crushing.
