W-mineralization from greisen at Cetoraz near Pacov, Czech Republic
Popis výsledku v původním jazyce
Studied locality is situated about 750 m NE from the Cetoraz village. The small tungsten deposit is surrounded by mostly moldanubian rocks, especially Pacov orthogneiss and sillimanite-biotite paragneiss. W-minerals occur in quartz veins and lenses withaccompanying greisen. Greisenization is developed in endocontact of the orthogneiss, it has form of silicification and muscovitization. Ore mineralization of this greisen is represented by wolframite, scheelite, gahnite, pyrite, molybdenite, chalcopyriteand native bismuth. Cassiterite, galena and gold are only accessoric. Wolframite in quartz gangue is associated with scheelite and albite. Wolframite forms black tabular aggregates with size up to 10 cm. It is usually accompanied by scheelite crystals and aggregates of yellow-brown color and size from few mm to 1 cm. Microscopic study revealed wolframite, scheelite and uncertain secondary phase of Fe and W, which is by chemistry closely related to some pyrochlore group minerals.
