Abstract The Hagen-Balve Reef Complex of the northern Rhenish Massif, Germany, is one best examples for globally widespread Givetian to Frasnian reefs. At its eastern end, in Hönne Valley, it reaches up 1000 metres thickness. In general, there limited knowledge concerning faunas and palaeoecology initial reef phases. A unique section at Binolen exposes sharp boundary between underlying, silicic...
