About Petrified Wood (Fossilized Wood)
Madeira Petrificada é madeira antiga onde a matéria orgânica original foi gradualmente substituída por minerais, principalmente quartzo, mas também calcite, pirite ou ouro, preservando a estrutura original da madeira. Este processo de permineralização pode demorar milhões de anos. A Floresta Petrificada do Arizona, com 225 milhões de anos, é um dos depósitos mais famosos. A madeira petrificada exibe os padrões de veios da madeira original, agora em calcedónia colorida e quartzo. É popular em joalharia decorativa e objectos de colecção pela sua beleza natural e história geológica fascinante.
