The pages on this path record Pierre Jardin's various experiments in forging relations between rocks and wood, from setting stones on stumps to planting rocks in trees. As he discovered, he wasn't the first to have this idea....
  
  Intimate relations between stone and wood occur through natural processes. Petrified wood is probably the best known example. This spectacular log in the Petrified Forest formed from a fallen tree buried in river sediment rich in silicon. This preserved the tree from decay, and then, as the silicon-rich water percolated through the log, the silicon combined with oxygen to form quartz crystals in the spaces in the tree tissues, forming permineralized fossils with minerals including amethyst, smoky quartz, rose quartz, and rock crystal quartz.
