| Caption: | Valley of the River Teign from Hunters Tor, Devon. |
| Description: | Looking east along the valley of the River Teign. The rock crags on the left of the picture are known as Sharp Tor and are composed of hornfelsed sandstones with subordinate mudstones (Culm) in the aureole of the Dartmoor granite. The hornfelses are isoclinally folded and dip to the left (north) at about 40 degrees. The wooded slopes on the right-hand side of the valley are occupied by hornfelsed Culm (Carboniferous) rocks, poorly exposed. The rocky slope on the right of the picture is composed of granite as is also the smooth base slope on the right-hand skyline. The Dartmoor granite is the largest of the five main bosses that occur on the south-west of England during the Armorican orogeny. The granites intruded as hot molten rock known as magma baked the country rocks to four miles from the contact. Close to the contacts the rocks were metamorphosed to hornfelses while on the margins the only evidence may be spotting in the argillaceous rocks. |
