JORNADA INTERDISCIPLINAR NA MINA DE SÃO DOMINGOS - “Minas, tecnologias e educação: convergências”, 7 de novembro de 2014, Mina de São Domingos – CM Mértola/ CeHFCi, Univ. Évora
Percursos geológicos e mineiros nas minas de São Domingos e Chança.
João Xavier Matos, Zélia Pereira, Maria João Batista, Daniel de Oliveira – Lab. Nac. Energia e Geologia.

As minas de São Domingos e de Chança localizam-se no concelho de Mértola e constituem exemplos de jazigos de sulfuretos maciços polimetálicos da Faixa Piritosa Ibérica (FPI), formados em ambiente marinho, durante o Devónico superior (382 a 359 Ma aproximadamente). As estruturas mineralizadas são formadas por massas de minério maciço e de tipo stockwork (veios entrecruzados), associadas a rochas vulcânicas e sedimentares afetadas por alteração hidrotermal (sílica, clorite e sericite) do Complexo Vulcano-Sedimentar (CVS) da FPI. Em ambos os casos, os jazigos afloram à superfície, estando representados por chapéus de ferro, correspondentes à zona de enriquecimento supergénico e consequente oxidação dos sulfuretos. Distanciadas entre si cerca de 5 km, as duas minas foram exploradas na época romana e no século XIX, tendo sido ambas concessionadas à empresa Mason & Barry.

Localizada no vale do rio Chança, a mina de Chança constitui um pequeno jazigo de sulfuretos maciços (pirite acompanhada de rara calcopirite, esfalerite e galena), com amplos stockwork intersetados em sondagem. A mina foi concessionada em 1877, laborando em pequenos períodos através de escavações de poços e de galerias. O chapéu de ferro é formado por hematite, limonite, goethite, sílica e provável cuprite e está bem exposto em Portugal, no Cerro das Minas e no Cerro do Ouro, e em Espanha junto ao poço de Tremancia. Com uma possança inferior a 40 m, a estrutura mineralizada apresenta uma atitude WNW-ESSE, 45NE. As rochas encaixantes incluem-se no CVS, sendo representadas por lavas riolíticas, brechas vulcanoclásticas e pomíticas e xistos siliciosos. Estas litologias estão bastante deformadas e foram afetadas por alteração hidrotermal, bem expressa no corte geológico ao longo do rio. A mina de Chança situa-se no extremo ocidental de um alinhamento de jazigos de pirite espanhóis que inclui de oeste para leste Vuelta Falsa, El Carmen, San Fernando,Los Silos, Romanera, El Cura e Sierrecilla.
