Em todo o mundo, o homem está sempre à procura de maneiras de melhorar a sua vida. A maneira mais rápida é usar tudo o que existe na natureza, como a fauna, a flora e os recursos minerais... Estes últimos são considerados uma riqueza e variam de paÃs para paÃs. Em geral, é a raridade dessa riqueza que a valoriza a nÃvel económico. Até hoje, o futuro depende da natureza e da nossa responsabilidade. Graças a isso, o nosso primeiro trabalho é tentar conhecer tudo o que nos rodeia e a sua evolução: ou seja, descrever os materiais que constituem o nosso globo e a sua evolução, o que pode ser resumido numa única palavra: geologia. Na geologia, combinamos vários estudos para recolher informações sobre uma região ou um paÃs, tais como o estudo geomorfológico, a geoquÃmica, a mineralogia e outros. As informações assim obtidas fornecem-nos informações precisas sobre a localização dos recursos naturais existentes. Posteriormente, interessar-nos-emos pelo estudo dos recursos do subsolo, desde pedras preciosas a pedras semipreciosas, por vezes surpreendentes pela sua beleza excecional.
