The FSCRocks guidefeatures over 60 igneous, sedimentary and metamorphic rocks.

Rocks are everywhere. Crushed rock is, for example, an ingredient for making road surfaces. Stone and brick, made from clay, are both important in construction. Many houses have roofs of slate. In gardens rocks provide decoration and paving. Rock salt is on many tables. Sometimes polished slabs of beautifully crystalline granite decorate the front of shops and offices. And exposures of rock occur widely, especially in river valleys and at the seaside.

Photographs and text describe how to recognise each rock in the field.
