5.8 Chalk is produced in relatively small quantities from up to 12 quarries within the Chalk Downlands area and the smaller outcrop of chalk at Portsdown Hill. It is estimated that in recent years around 200,000 tonnes of chalk have been produced annually. About three-quarters of this has been used as constructional fill material, but Hampshire also produces chalk for use as agricultural lime and has produced chalk for industrial processes.
