Imperial College Rock Library

Identify Tools

The Rock Library provides identify tools to help develop rock and mineral identification skills. It is not possible to instantly recognise every rock type and mineral, instead proper identification is achieved by systematically querying the properties of the material. The identify tools provides a guide to the type of questions involved in identifying Earth materials and at each step provides a list of possible identities.
