Arthurs Seat Rock, Edinburgh. Midlothian. Scotland. United Kingdom.
Informations supplémentaires:
Like the castle rock on which Edinburgh Castle is built, it was formed by an extinct volcano system of Carboniferous age (approximately 350 million years old), which was eroded by a glacier moving from west to east during the Quaternary (approximately the last two million years), exposing rocky crags to the west and leaving a tail of material swept to the east.[5] This is how the Salisbury Crags formed and became basalt cliffs between Arthur's Seat and the city centre. From some angles, Arthur's Seat resembles a lion couchant. Two of the several extinct vents make up the 'Lion's Head' and the 'Lion's Haunch'. Arthur's Seat and the Salisbury Crags adjoining it helped form the ideas of modern geology as it is currently understood. It was in these areas that James Hutton observed that the deposition of the sedimentary and formation of the igneous rocks must have occurred at different ages and in different ways than the thinking of that time said they did. It is possible to see a particular area known as Hutton’s Section in the Salisbury Crags where the magma forced its way through the sedimentary rocks above it to form the dolerite sills that can be seen in the Section.
