Analyses à la microsonde électronique des oxydes des formations de contact, pegmatite stockscheider et filons stannifères (« quartzglocke ») (Mn et Mg sous le seuil de détection pour la cassitérite). Manganocolumbite et qitianlingite sont en intercroissance (cf. Fig. 7).
Major and minor element composition of mineral oxides from contact units (stockscheider pegmatite and Sn-bearing quartz veins, or quartzglocke) determined by EPMA (Mn and Mg below detection limit for cassiterite). Manganocolumbite and qitianlingite are intergrown (cf. Fig. 7).
