• Description: Pyromorphite samples from weathering zone of the vein deposit Nová Ves at Rýmařov are identified and studied with respect to their origin. Pyromorphite was found in assemblage with limonite and plumbogumite. Pyromorphite crystals have zonality, lighter zones (in BSE image) with higher Pb alternate darker zones with hogher Ca. Changes in fluids composition and pH during crystallization of pyromorphite are in connection with described zonality.
