El campo pegmoaplítico de Doade (Ourense) y sus mineralizaciones de Sn y Ta asociadas

Abstract

[Abstract] This paper deals with the analysis of the geology and structure of the pegmoaplitic field of Doade (Ourense, Spain). Several bodies are distinguished taking into account their mineralogy and spatial distribution. The composition shows the existence of four types of pegmoaplites, all of them corresponding to the same family in different evolutionary stages, in accordance with their spatial distribution (a clear zonality from the granite boundary into the metamorphic rock). Also the study of the greinesization process and the casiterite contain is carried out.
