CAD. LAB. XEOL. LAXE 26 (2001) Estruturas Filonianas da Serra do Marão 145 Tabela 1. Análises químicas e fórmulas estruturais das biotites dos filões máficos do Ramalhoso. Geoquímica de rocha total As análises químicas médias de elementos maiores, menores e terras raras de cada um dos filões estudados são dadas na tabela 2. Trata-se de rochas de composição intermédia, pois o teor de SiO 2 é de cerca de 56%, Atendendo à sua mineralogia, escassez de quartzo e feldspato potássico, à sua textura e composição química, a classificação mais adequada destas rochas é de doleritos ou metadiabases. Em termos composicionais estas rochas projectam-se no campo dos andesitos ou no limite deste com os basaltos, no diagrama TAS. Classificam-se como traqui-andesitos (figura 3) no diagrama de WIN- CHESTER E FLOYD (1977). A utilização deste diagrama é recomendada porque utiliza elementos muito pouco móveis durante o metamorfismo, oferecendo uma boa informação sobre a natureza dos materiais originais. Nos diversos diagramas, que combinam elementos estáveis durante o metamorfismo (Ti, P, Zr, V e Nb) propostos por WINCHESTER E FLOYD (1976) para discriminar se o magma original será basalto toleítico ou alcalino estas amostras projectam-se sempre no domínio alcalino (figura 4).
