Pebble spotting with The Pebbles on the Beach


1 Ovoid pebble of grey granite
2 Grey granite with one surface cut and polished
3 Pebble of schist with one surface cut and polished. The laminations are more clearly seen on an uncut surface
4 Flattened ovoid pebble of crystalline limestone [unpolished]
5 Fragment of whitish chert. Its angularities show that it has not been smoothed by the action of the tides for long
6 Portion of a rounded flint pebble. Note the thick, white coating that the grey flint has acquired on the beach
7 Well-rounded pebble of fine-grained red sandstone
8 Flattened ovoid pebble of conglomerate

10 Fragment of jet from the Yorkshire coast, near Whitby
11 Ovoid pebble of red serpentine [unpolished]
12 Flattened ovoid pebble of schist [unpolished]. The wearing down of the stone has given the laminations on the upper side a quaint resemblance to two eyes looking through spectacles
13 Cut and polished surfaces of an ovoid pebble of dolerite from the Whin Sill. The glossy black of the polished surface contrasts with the grey, speckled and worn exterior
