Geology

5.1 In simple geological terms, Hampshire can be divided into four main areas: the Chalk Downlands; the Hampshire Basin; the London Basin; and the Wealden Edge. These areas are shown in Figure 1.

5.2 Within the County there are economic mineral resources of sand and gravel, solid sand, chalk, clay, and oil and gas. All of these minerals are currently being worked to a greater or lesser extent. The most important, in terms of quantity produced, are sand and gravel and solid sand, which are used as aggregates. Existing mineral working sites in Hampshire are listed in Appendix 6.
