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.
Na Serra do Rosalgar ocorrem ainda conglomerados terciários em que a matriz ferromanganesífera cimenta blocos de xisto, quartzo e quartzito.
