Caption: Volcanic dyke. Tertiary volcanic intrusion in a rock face. This rock formation is commonly known as a dyke. Dykes are sheets of rock, usually igneous, that cut across the bedding or structural planes of the host rock. Igneous (volcanic) dykes form as molten rock (magma) flows between cracks in the host rock and then cools and solidifies. An igneous dyke normally intrudes in a more or less vertical position and some dykes of this nature extend for considerable distances.
