Description | The locality Krucemburk is well known by its historical occurrence of secondary Cu-phosphate pseudomalachite. A new revision of supergene minerals confirmed pseudomalachite while other polymorph (reichenbachite, ludjibaite) were not identified. Sporadic grains of descloizite were found. Chemical composition and X-ray diffraction pattern of studied minerals are given. Malachite, the dominant copper mineral of the supergene zone forms thin coatings on phylites. Unspecified Cu-S minerals of the chalcocite-digenite group, minute grains of acanthite, relics of galenite, chalcopyrite and supergene baryte only locally occur. |
