Minerals of Jersey

Minerals are made from elements like silicon, oxygen, aluminium, iron and other metals.

They are the fundamental building blocks of all rocks. As magma (molten rock) cools, minerals such as quartz and feldspar form crystals. The longer the cooling process takes, the larger the crystals. Minerals can also be carried through rocks by water, forming crystals as the water evaporates. Different minerals bring out different colours in the rock.
