The planet in a pebble - a journey into earth's deep history
Every pebble has many stories to tell. Its particular atoms, its crystals, its minerals, its grains, its textures, its strata, its tiny fossils bear evidence to a history that stretches back billions of years. This book takes us on a journey through the past of a pebble of Welsh slate, showing how scientists tease out the clues of its history. Captured within are grand stories that reach back to long dead stars, into the depths of the Earth, to vanished continents, and quiet ocean beds above which strange creatures swam.
