Scheelite and gold-bearing mineralization in the ptasznik roof pendant, sudetes, poland

摘要

Scheelite and gold-bearing mineralization in quartz veins and stockworks is a result of metasomatic and hydrothermal processes in metamorphic rocks of the Ptasznik roof pendant of the Klodzko-Zloty Stock intrusion. Scheelite-titanite mineralization preceding Au and/or sulphide-bearing quartz mineralization originated in zones of a strong silicification and K-feldspar metasomatism at the temperature of about 460 deg. Chemical analyses determined 0.3 wt.
