O QUE SIGNIFICA HORNBLENDE EM INGLÊS
Hornblende
Hornblende é uma série complexa de minerais inosilicados. Não é um mineral reconhecido por direito próprio, mas o nome é usado como um termo geral ou de campo, para se referir a um anfíbio escuro. Hornblende é uma mistura isomorfa de três moléculas; um silicato de cálcio-ferro-magnésio, um silicato de alumínio-ferro-magnésio e um silicato de ferro-magnésio. A fórmula geral pode ser dada como 2-358O222.
