| Description | Chemical composition of tourmaline in the elbaite-subtype granitic pegmatite at Dolní Rožínka records evolution of pegmatitic melt during crystallization. Chemistry of six textural-paragenetic types of tourmaline. Evolution of tourmaline in the Li-pegmatite at Dolní Rožínka is in many aspects (such as tourmaline textures and chemical composition) similar to the elbaite-subtype pegmatite at Pikárec (which reached higher amounts of Mn). On the other hand, the elbaite pegmatite at Řečice is texturally and chemically (especially in higher F and Ca contents in tourmaline) rather different. |
