Abstract

In the original language

The Minh Tien pegmatite in northern Vietnam is an elbaite-subtype granitic pegmatite with a mixed LCT+NYF geochemical signature. Tourmaline composition corresponds to fluor-liddicoatite, fluor-elbaite, and rarely also a Pb-analogue of fluor-liddicoatite. The primary lead enrichment in tourmaline is related to alteration of amazonite. Textural relations show that the Pb-rich tourmaline (Tur 1) formed together with lepidolite during metasomatic albitization of K-feldspar, and the further three generations formed during hydrothermal reaction of Li,B,F-rich fluids with Tur 1, K-feldspar and albite.

In Czech

Pegmatit Minh Tien v severním Vietnamu je granitický pegmatit elbaitového subtypu se smíšenou geochemickou signaturou LCT+NYF. Složení turmalínu odpovídá fluor-liddicoatitu, fluor-elbaitu, a vzácně též Pb-analogu fluor-liddicoatitu. Primární nabohacení Pb v turmalínu je vázáno na alteraci amazonitu. Texturní vztahy ukazují, že Pb-bohatý turmalín (Tur 1) vznikl spolu s lepidolitem během metasomatické albitizace K-živce, a další tři generace vznikly hydrotermální reakcí Li,B,F-bohatých fluid s Tur 1, K-živcem a albitem.
