A silicified, limonitized wood piece with quartz druse from the Zwenkau opencast lignite mine near Leipzig exemplifies multiple stages of wood transformation in a Tertiary lignite environment. The wood was initially permineralized or replaced by silica-rich solutions, gradually substituting organic matter with microcrystalline quartz. Subsequent limonitization occurred as iron-bearing fluids infiltrated the already silicified wood, depositing limonite (brown ironstone) along cracks or structural features. The overgrowth of quartz druse on the surfaces indicates a later open cavity phase where clear quartz crystals precipitated from silica-saturated waters. Overall, this specimen documents successive diagenetic and mineralization phases in the former lignite mining area.
