Popis:	The Givetian to Frasnian Elbingerode Complex, situated in the Harz area (Germany), corresponds to an atoll-like reef formed by corals and stromatoporoids on a group of submarine volcanoes. Circularly arranged stratovolcanoes enclosed a central lagoon containing up to 600 m of Givetian backreef limestones. Three of the four volcanoes were surrounded by fringing reefs; one of them remained permanently in a deeper water position.
