THE PLANET IN A PEBBLE

This is the story of a single pebble It is just a normal pebble as you might pick up on holiday on a beach in Wales say Its history though carries us into abyssal depths of time and across the farthest reaches of space This is a narrative of the Earth s long and dramatic history as gleaned from a single pebble It begins as the pebble particles form amid unimaginable violence in distal realms of the Universe in the Big Bang and in supernova explosions and continues amid the construction of the Solar System Jan Zalasiewicz shows the almost incredible complexity present in such a small and apparently mundane object Many events in the Earth s ancient past can be deciphered from a pebble volcanic eruptions the lives and deaths of extinct animals and plants the alien nature of long vanished oceans and transformations deep underground including the creations of fool s gold and of oil Zalasiewicz demonstrates how geologists reach deep into the Earth s past by forensic analysis of even the tiniest amounts of mineral matter Many stories are crammed into each and every pebble around us It may be small and ordinary this pebble but it is also an eloquent part of our Earth s extraordinary never ending story
