Inactive Fe-Mn mine.
Dois filões de quartzo e óxidos de ferro e manganês, orientados N50ºE e 50º a 60ºSE e com 3.100 m de comprimento; a nordeste do filão do Rosalgar surgem as impregnações de Fe-Mn em xistos.
Two quartz veins with iron and manganese oxides, oriented N50ºE and dipping 50º to 60ºSE, with a length of 3,100 m; northeast of the Rosalgar vein, Fe-Mn impregnations appear in the schists.
Na Serra do Rosalgar ocorrem ainda conglomerados terciários em que a matriz ferromanganesífera cimenta blocos de xisto, quartzo e quartzito.
In the Serra do Rosalgar, there are also Tertiary conglomerates in which a ferromanganese-rich matrix cements blocks of schist, quartz, and quartzite.
