| Description | The elbaite-subtype granitic pegmatite at Dolní Rožínka shows complex magmatic and metasomatic/hydrothermal history of crystallization from two types of pegmatitic melt followed by hydrothermal overprint, well recorded by tourmaline compositional and textural evolution. Primary magmatic tourmaline shows a gradual enrichment in Al+Li and Mn and decrease of Fe+Mg; transition to hydrothermal stage caused change of habitus to fibrous only. Hydrothermal fluids that metasomatically reacted with early minerals are strongly enriched in Ca and F. |
