Molybdenite occurs in thin quartz veins where it lies along the vein walls or within the vein as discrete laths, polycrystalline clots or rosette-shaped aggregates. Magnetite associated with minor haematite occurs in quartz veins and is rimmed and cross-cut by pyrite. Hubnerite occurs with pyrite and topaz in quartz veinlets. Pods of molybdenite, magnetite, pyrite, topaz and muscovite are present |
