Regional Report: Laach lake volcanic complex, Eifel Mts, Rhineland-Palatinate, Germany

Pyroclastic formation of several eruptive centres in the area of Mendig and in the northern part of Laach Lake with tuffs, ash-flows and pumice layers of phonolitic and trachytic composition. Late stage eruption of grey tuffs (“Graue Laacher-See-Tuffe”) with xenoliths of different origin (fragments of the Devonian basement, quartz veins, micaschist, crystalline schist, metasomatites, subvolcanites, sanidinites and tephrites). There are various mineral localities around the lake - pumice quarries, sand pits and road cuts. The most significant ones are: - Pumice quarries south of Thelenberg mountain - Pumice quarries in the area of Wingertsberg mountain - Pumice quarries in the area “In den Dellen” - Pumice quarries east of Krufter Ofen mountain - Fields west of Laach lake, near Glees
