Description | Svornostite (IMA2014-078), K2Mg[(UO2)(SO4)2]2 8H2O, is a new uranyl sulfate mineral from Jáchymov, Western Bohemia, Czech Republic. The new mineral was found in material originating from the Geschieber vein in the Svornost mine. It occurs as crystalline crusts composed of yellow prismatic crystals on a gangue along with geschieberite, adolfpateraite and gypsum. It is a low-temperature, supergene mineral formed by the post-mining weathering of uraninite. Svornostite is orthorhombic; the crystal structure has been refined to R = 0.023 for 2745 unique observed reflections. |
